By using these two distinct ticket types, you can effectively gather the necessary information for assisting employees with their QA testing needs for both “built” and “bought” applications. This structure allows for a more tailored approach, ensuring a better overall QA process.

Refine built

“Let’s refine ‘built’ a bit. I’m not thinking only end-to-end / integration / HTTP-based tests. I’m even thinking that the form could give junior developers an opportunity to request a consultation from a senior test engineer about designing and implementing a unit test that simply runs as part of the application’s build process. (Although I’m still thinking that integration / end-to-end / HTTPS tests are also important.) Again, feel free to split this into two forms if you’d like, although I feel like one form might be simpler. But I’ll leave it up to you.”

Okay, let’s refine the “built application” QA test request form to accommodate requests ranging from unit tests to integration/end-to-end tests, and even HTTP-based tests. Given the range of test types you’d like to cover, a single form might be simpler for users, so I’ll present a single, more flexible form.

Refine buy (“building upon SaaS: essential development considerations”)

Take 1

What types of “build” might an enterprise still need to do even if they decide to “buy” a SaaS? Here are some examples I can think of so far:

1. A version control repository full of the SaaS configuration settings crucial to the business, and CI/CD pipelines to keep all instances of the SaaS (dev, stg, prd, various ephemeral instances of the SaaS that the vendor allows power users to spin up, etc.) configured accordingly.
2. A secrets management tool so that power users and CI/CD pipelines can all access teamwide secrets required for configuring the SaaS appropriately.
3. A version control repository full of definitions for the synthetic monitoring probes (including schedules and what to do with results) that should be constantly run against the SaaS’s various environments (dev, stg, prd, any ephemeral instances that get spun up, etc. – although of course particularly “prd”).

I feel like there’s so much more I should be warning the enterprise that still needs to be “built” even when you “buy.” But maybe that’s just me doubting myself. Maybe I already thought of everything.

Thoughts?

It appears you’ve already identified several key areas that an enterprise needs to “build” even when adopting a SaaS solution. These include managing configurations, secrets, and monitoring, but you’re right, there’s more to consider. Here’s a breakdown of additional “build” efforts based on the sources, and some thoughts about what you’ve already listed:

• CI/CD Pipelines for SaaS Configurations: As you noted, maintaining a version-controlled repository for SaaS configurations is essential. This includes setting up CI/CD pipelines to ensure consistent deployments across different environments. The sources emphasize that CI/CD is crucial for consistent and automated deployments.
  • This is important because it helps to manage changes to the SaaS configuration in the same way that the enterprise would manage changes to its own applications, ensuring a level of control and repeatability that is vital for stability and reliability.
• Secrets Management: You’ve correctly identified the need for a robust secrets management tool. This is crucial for securely managing API keys, passwords, and other sensitive information needed to configure and access the SaaS.
  • The sources highlight that secure secrets management prevents sensitive information from being hardcoded into applications or stored insecurely.
• Synthetic Monitoring Probes: You’ve also rightly pointed out the need for defining and managing synthetic monitoring probes. These probes are necessary to ensure the SaaS is performing as expected, especially in critical “prd” environments.
  • The sources emphasize the importance of monitoring and observability.

Here are some additional areas that an enterprise will likely need to build even when adopting a SaaS:

• Automated Testing: Even with a SaaS solution, your organization will need to develop and implement automated testing strategies. This includes:
  • Integration testing: Ensuring the SaaS integrates correctly with other internal systems. This is particularly important when data and services flow between a SaaS and other systems in your infrastructure.
  • End-to-end testing: Validating complete workflows that involve the SaaS. This helps to make sure that the SaaS integrates well into the workflows it supports.
  • Performance testing: Checking the SaaS performs acceptably under load. This includes checking response times, throughput, and other important performance metrics to make sure that the SaaS meets user expectations.
  • Security testing: Scanning for vulnerabilities in the SaaS. The sources suggest that security testing should be integrated into the CI/CD pipeline.
    • The sources emphasize the importance of test automation, integrating tests into the CI/CD pipeline, and incorporating security testing into the QA process.
• Compliance Automation: Depending on the industry, your organization will need to implement compliance checks and reporting, and automate these processes. This will likely involve using tools that can check security policies and configurations for compliance with industry standards, and the automation of compliance checks will help to minimize human error.
• Infrastructure as Code (IaC): While the SaaS itself might not need IaC, the systems that interact with it, or the monitoring and alerting infrastructure, might need to be managed as code to ensure consistency and repeatability. The sources note that IaC facilitates consistent and repeatable deployments.
• Monitoring and Observability Infrastructure: You will need to build monitoring and observability tools to track the performance of the SaaS and its integrations. This will likely include APM tools, infrastructure monitoring, and log aggregation.
  • The sources emphasize the importance of monitoring for application performance, infrastructure health, and security threats.
• Security Integrations: You may need to build security integrations between your environment and the SaaS, including identity and access management, and other security tools. This should help ensure that your SaaS environment is as secure as the rest of your infrastructure.
• Knowledge Sharing and Training: The team will likely need knowledge-sharing sessions, documentation, and training materials related to the SaaS configuration, operation and troubleshooting. This will help ensure that all team members can use and maintain the SaaS effectively.
• Incident Response Plans: It is important to have clear incident response plans that cover the SaaS, just like your other systems. This should include procedures for identifying, containing, eradicating and recovering from incidents.

You’re not doubting yourself; there is indeed a significant amount of “building” required even when adopting a SaaS. It’s essential to recognize that adopting a SaaS is not a “set it and forget it” proposition, but instead requires building around that SaaS to support its integration into your existing ecosystem. This includes the build and maintenance of infrastructure, CI/CD pipelines, testing, security, compliance, and observability capabilities.

Take 2

“Thanks. This is great. Although for what it’s worth, I’ve found that other than the plain-English artifacts like training and response plans, most of the technologically ‘developable’ artifacts sort of roll up under QA-related concepts I already thought of when I was thinking synthetic monitoring. I know that you’re replying based on what we’ve already talked about and the sources I’ve already given you, but is there anything else extremely far ‘outside the box’ that you’d like to add?”

It’s good to hear that the previous response was helpful and that you’ve identified the overlap between several areas of “build” and QA. Based on the sources and our conversation history, here are some additional points that are a bit further “outside the box” that you may want to consider, focusing on areas that might not be immediately apparent when thinking about adopting a SaaS:

• Metrics for SaaS Integration: While you’ve considered synthetic monitoring, also consider metrics specifically related to the SaaS integration and its impact on the business. The sources emphasize the importance of aligning DevOps with business objectives. This could involve tracking metrics such as:
  • Business value mapping: How many DevOps initiatives, including those related to SaaS integration, are mapped to specific business outcomes, and the quantifiable impact on business metrics such as revenue growth or customer satisfaction.
  • Lead time of value delivery: How quickly a new feature or change in the SaaS is delivered to users, and how the SaaS is impacting your ability to deliver value to your customers.
  • Stakeholder satisfaction: Whether the SaaS is meeting the needs of the stakeholders and business leaders who use it, and whether the implemented DevOps practices around the SaaS are aligned with stakeholder needs.
  • Cost of the tools: Whether the cost of the SaaS and the tooling used to support it, are aligned with their value.
• Policy as Code for SaaS: You mentioned managing SaaS configurations but consider implementing security and compliance policies as code for those configurations. This helps to automate enforcement and reduce human error. For example, you could use policy-as-code to ensure that all instances of the SaaS conform to security and compliance requirements, and you could track the percentage of your SaaS deployments that are governed by policy-as-code.
• Compliance Automation for SaaS: Beyond basic security measures, think about automating compliance checks and reporting specifically for the SaaS. This could include automating checks against industry standards or regulatory requirements, and automating the generation of compliance reports to help demonstrate your adherence to those standards.
• DevSecOps Training related to SaaS: Ensure your teams are trained in DevSecOps practices specifically related to SaaS. This includes training on secure configuration, secrets management, and security testing. You can track the percentage of teams who have completed the training and test their knowledge retention.
• Vulnerability Management for SaaS: Implement regular vulnerability scanning of the SaaS and its integrations, and establish clear processes for tracking and remediating identified vulnerabilities. The sources note that this includes static application security testing (SAST), dynamic application security testing (DAST), and software composition analysis (SCA). Track how long it takes to remediate vulnerabilities and the number of outstanding vulnerabilities in your SaaS.
• Incident Response for SaaS: Develop incident response plans that specifically address issues related to the SaaS, ensuring that teams know how to respond to security incidents, performance issues, or outages related to the SaaS. This might include specific procedures for contacting the vendor, and how you would manage the process of rolling back a deployment. Measure how quickly your teams can detect security incidents and how long it takes to recover from them.
• Knowledge Sharing specific to SaaS: Encourage the creation and maintenance of documentation specific to the SaaS, including configurations, workflows, and troubleshooting steps. Also promote regular knowledge sharing sessions, and measure how often the documentation is being used.
• Toolchain Integration for SaaS: It’s important that the tools you are using are well integrated and working together effectively. Track the tool integration success rate and how any tool malfunctions are impacting the team, and track the overall efficiency of the toolchain.
• Retroactive Metrics for SaaS: The sources discuss how you can measure metrics retroactively by querying existing systems. Use this capability to establish a baseline and monitor the impact of the SaaS on key technical metrics like deployment frequency, build frequency, build success rate, build time, average response time, error rates, and test automation.

These points are intended to prompt you to consider areas beyond the immediate technical implementation of a SaaS solution, and to consider how the SaaS will impact the business more broadly. While you’ve covered the core technical aspects related to QA and monitoring, these additional points may be helpful as you explore the periphery of what a SaaS deployment might need in your organization.

Take 3: “Congrats – you bought a SaaS!” (“Building a successful SaaS ecosystem”)

“Creative writing exercise: could you write me a helpdesk article titled ‘Congrats – you bought a SaaS!’?”

Okay, here is a draft of a helpdesk article titled “Congrats – you bought a SaaS!”:

Congrats – You Bought a SaaS!

So, you’ve decided to leverage the power of a SaaS (Software as a Service) solution! That’s a great step towards improving efficiency and focusing on your core business. But before you dive in, it’s important to understand that even when you “buy,” there’s still a fair bit of “building” that needs to happen to ensure the SaaS integrates smoothly with your existing environment and meets your specific needs. This article outlines what you need to consider as you embark on your SaaS journey.

It’s Not “Set It and Forget It”

Think of your new SaaS as a powerful engine for your organization, but like any engine, it needs a vehicle to drive it. That vehicle is the supporting infrastructure, processes, and culture that you will need to “build.”

Here are the key areas to consider:

• CI/CD for SaaS Configurations: Just like your own applications, your SaaS configuration needs to be managed carefully.
  • You’ll need a version control repository to track all configuration changes.
  • Implement CI/CD pipelines to ensure consistent configuration across all your SaaS environments (dev, staging, production, etc.). This helps to ensure that your SaaS deployments are consistent, and repeatable.
• Secrets Management: Securely managing sensitive information is crucial.
  • Implement a robust secrets management tool to handle API keys, passwords, and other credentials. This will prevent sensitive information from being hardcoded into applications or stored insecurely.
• Synthetic Monitoring: It is important to continuously monitor your SaaS, especially your production environment.
  • Define and manage synthetic monitoring probes to ensure the SaaS is performing as expected.

Going Further: Building the Infrastructure Around Your SaaS

Beyond these basics, you’ll need to build capabilities around your SaaS to ensure its seamless integration and ongoing success.

• Automated Testing: Testing is key to ensuring your SaaS is working correctly and integrating well with your systems.
  • Develop integration tests to verify the SaaS interacts correctly with your internal systems.
  • Implement end-to-end tests to validate complete workflows that involve the SaaS.

  • Hold knowledge-sharing sessions and create documentation and training materials.
• Incident Response: Be prepared to deal with issues promptly.
  • Have incident response plans that cover the SaaS, just like your other systems.

Important Considerations:

• Metrics Matter: Focus on business value and efficiency.
  • Track how your SaaS contributes to business outcomes. For example, the number of DevOps initiatives mapped to business outcomes can help to show how the SaaS is impacting the business. Also, look at the quantifiable impact of DevOps on business metrics.
  • Monitor metrics like lead time of value delivery, showing how quickly you can deliver features to users.
  • Assess stakeholder satisfaction with your SaaS.
• Policy as Code: Implement security and compliance policies as code for your SaaS configurations to automate enforcement and reduce human error.
• Compliance Automation: Automate checks against industry standards and regulatory requirements.
• DevSecOps Training: Train your teams in DevSecOps practices specifically related to your SaaS. Track the percentage of teams completing security training, and test their knowledge.
• Vulnerability Management: Implement regular vulnerability scanning of the SaaS and its integrations, and establish clear processes for tracking and remediating vulnerabilities. Track the average time to remediate critical vulnerabilities.
• Incident Response: Develop incident response plans that specifically address issues related to the SaaS, and track metrics like time to detect security incidents.
• Knowledge Sharing: Encourage the creation of documentation specific to the SaaS, and track metrics like the usage of shared documentation.
• Toolchain Integration: Track the tool integration success rate, and monitor how any tool malfunctions are impacting the team.
• Retroactive Metrics: Use existing data to establish a baseline and monitor the impact of the SaaS on key technical metrics, including deployment frequency, build frequency, build success rate, build time, average response time, error rates, and test automation.

In Conclusion

Adopting a SaaS solution is a strategic decision that can greatly benefit your organization. However, it’s important to recognize that it is not a “set it and forget it” proposition, but instead requires building around that SaaS to support its integration into your existing ecosystem. By proactively addressing the areas outlined above, you can ensure a successful SaaS implementation that drives efficiency, security, and compliance.

Take 4: the pizzeria (“Building a successful SaaS implementation: a pizzeria case study”)

“Can you please add an ‘examples’ auxiliary article that walks through each of this article’s recommendations, with the example application being a pizzeria’s SaaS? Feel free to get into creative sub-examples, talking about the business’s interests in toppings and busy times, etc. Go wild.

Okay, here’s an auxiliary article that provides examples for each recommendation in the “Congrats – You Bought a SaaS!” helpdesk article, using a pizzeria’s SaaS as the example application:

Examples: Applying SaaS Recommendations to “Pizza Time,” a Pizzeria’s SaaS

Let’s take a look at how a pizzeria, which we’ll call “Pizza Time,” could apply the recommendations in the “Congrats – You Bought a SaaS!” article. Pizza Time recently purchased a SaaS platform to manage online orders, delivery, and customer loyalty. Here’s how they might approach the “build” around their “buy”:

CI/CD for SaaS Configurations

• Recommendation: Manage SaaS configuration with version control and CI/CD.
• Example:
  • Pizza Time stores all its configuration settings for their SaaS platform in a Git repository. This includes settings for:
    • Menu items and prices: They track every change to the menu, such as the addition of a new “Spicy Pineapple” pizza or seasonal price adjustments, with each change as a commit to the repo.
    • Delivery zones: They manage the geographic areas where they deliver, with changes logged in their version control.
    • Loyalty program rules: They track changes to their loyalty program, including points awarded for each purchase, or discounts for repeat customers.
  • Pizza Time sets up CI/CD pipelines using GitLab CI. Whenever a change is pushed to the Git repository:
    • The pipeline automatically updates the development instance of the SaaS with the changes.
    • After testing, the changes are promoted to the staging environment for further testing.
    • Once approved, the changes are automatically deployed to the production environment.

Secrets Management

• Recommendation: Use a robust secrets management tool.
• Example:
  • Pizza Time uses a tool like HashiCorp Vault to securely manage API keys and passwords.
    • The API key for the delivery service integration is stored in the vault and used by the SaaS platform.
    • The database password for the customer database is also securely stored and accessed using the secrets management tool.
    • Employee passwords to various business tools are stored securely and accessed using the vault as an identity provider.
  • They configure the SaaS platform and CI/CD pipelines to fetch these secrets from Vault, avoiding any hardcoding of sensitive information.

Synthetic Monitoring

• Recommendation: Define and manage synthetic monitoring probes.
• Example:
  • Pizza Time sets up synthetic monitoring probes using a tool like Prometheus and Grafana to constantly check the availability of their SaaS platform:
    • A probe is set up to check if the ordering page is available every 5 minutes from various locations such as New York, London and Tokyo, simulating customer access from different parts of the world.
    • A probe is set up to monitor the API endpoint used by the mobile app to place orders. This ensures the mobile app is functioning correctly and that the API is responding as expected.
    • They also set up probes to check that customer loyalty points are being awarded correctly every 15 minutes.
    • Alerts are configured so that if any of the probes fail, the operations team is immediately notified.

Automated Testing

• Recommendation: Implement integration, end-to-end, performance, and security testing.
• Example:
  • Integration testing:
    • Pizza Time creates automated tests that verify that the SaaS platform correctly integrates with their payment gateway. For example, the test checks if orders are processed correctly and payments are authorized.
    • They test that customer data, including delivery addresses, are correctly passed from the SaaS platform to their in-house delivery management system.
  • End-to-end testing:
    • They use a tool like Selenium to create automated tests that simulate a customer placing an order from start to finish. This includes browsing the menu, adding items to the cart, entering payment information, and confirming the order.
  • Performance testing:
    • Using a load testing tool, they simulate high traffic during peak hours (lunch and dinner rushes) to ensure the SaaS can handle the load, measuring response times for key customer actions such as searching for pizza toppings and updating an order.
  • Security testing:
    • They integrate security testing tools like SAST and DAST into their CI/CD pipeline. These tools automatically scan for vulnerabilities in their SaaS configurations and integrations, checking for potential vulnerabilities in the menu items and customer data handling processes.

Compliance Automation

• Recommendation: Automate compliance checks and reporting.
• Example:
  • Pizza Time, which is subject to PCI DSS standards for handling payment information, uses an automated system to verify that:
    • Payment data is encrypted both in transit and at rest. This helps to verify that card data is being processed and stored securely.
    • Access to the customer database is strictly controlled with multi-factor authentication. This helps ensure that customer data is accessed only by authorized personnel.
  • The system also automatically generates reports that demonstrate compliance, and alerts Pizza Time’s security team when compliance drifts from established standards.

Infrastructure as Code (IaC)

• Recommendation: Manage supporting infrastructure with IaC.
• Example:
  • Pizza Time manages the infrastructure for its monitoring systems and the databases that store customer loyalty data using Terraform:
    • Terraform code is used to provision and manage the servers and databases used by the monitoring tools. This code ensures that infrastructure components are configured consistently and can be easily rebuilt if needed.
    • Changes to the infrastructure are tracked in version control, and the infrastructure is automatically updated when changes are pushed to the Git repository.

Monitoring and Observability Infrastructure

• Recommendation: Set up monitoring and observability tools.
• Example:
  • Pizza Time sets up:
    • APM tools to track the performance of the SaaS, identifying bottlenecks and improving response times. They monitor response times for the ordering system, the delivery service API, and any integration points that the SaaS might have.
    • Infrastructure monitoring tools to track the health of their servers and databases, monitoring CPU usage, memory, and disk space. This allows them to see if the systems supporting their SaaS are working correctly.
    • Log aggregation tools to collect and analyze logs, identifying issues and security threats. They are collecting logs from their web servers, application servers and databases, which are being analyzed to monitor both application performance, and to identify any security threats or patterns.

Security Integrations

• Recommendation: Build security integrations between your environment and the SaaS.
• Example:
  • Pizza Time implements:
    • Single sign-on (SSO) so employees can securely access the SaaS using their existing corporate credentials. This makes it easier for employees to access their SaaS and reduces the likelihood of using weak or compromised passwords.
    • Regular security audits to ensure that the SaaS is compliant with industry security standards.
    • Data loss prevention (DLP) tools to prevent sensitive customer information from being accidentally or maliciously exposed.

Knowledge Sharing and Training

• Recommendation: Hold knowledge-sharing sessions, create documentation, and training materials.
• Example:
  • Pizza Time creates:
    • Documentation on how to configure and use the SaaS, including instructions on managing menu items and setting up delivery zones.
    • Training materials for employees who manage the online orders. They hold regular training sessions to make sure all employees can use the new SaaS effectively.
    • Troubleshooting guides for common issues. This is available to all employees who use the SaaS, and it is regularly updated when new issues are identified.
    • A knowledge base where employees can share tips and tricks for using the SaaS effectively.

Incident Response

• Recommendation: Have incident response plans that cover the SaaS.
• Example:
  • Pizza Time develops:
    • A clear incident response plan for any SaaS related issues, including:
      • A process for contacting the vendor, and escalating issues if necessary.
      • A plan for quickly rolling back changes in case a problem is identified after a change.
      • Instructions for quickly isolating systems in case of a security breach.
    • Regular drills to simulate potential incidents, including a server outage, a data breach or an interruption to their delivery service. This helps them to be prepared for any issues that might occur.

Metrics

• Recommendation: Focus on business value and efficiency.
• Example:
  • Pizza Time tracks:
    • The number of DevOps initiatives mapped to business outcomes, such as increases in online sales and improved customer satisfaction.
    • The quantifiable impact of DevOps on business metrics, such as increases in revenue and reductions in costs associated with delivery.
    • The lead time of value delivery, measuring how quickly they can add a new topping to the menu on the SaaS platform.
    • Stakeholder satisfaction, collecting feedback from the business team on the SaaS’s ease of use, and whether it is helping them to meet their objectives.
    • The cost of the SaaS, comparing its subscription costs with the business value it is delivering.
    • The percentage of compliance checks that are automated, demonstrating improved efficiency in compliance processes, and reducing the time it takes to provide compliance reporting.
    • The percentage of teams completing security training, showing how much the team is engaging with security best practices.
    • The average time to remediate critical vulnerabilities, measuring the time it takes to resolve a security incident in the SaaS.
    • The usage of shared documentation, monitoring how often employees are accessing guides on troubleshooting the SaaS and using it effectively.
    • The tool integration success rate, measuring the percentage of successful integrations between the SaaS and other tools in their tech stack.
    • Retroactive Metrics such as deployment frequency, build frequency, build success rate, build time, average response time, error rates, and test automation to monitor the impact of the SaaS over time.

By following these examples, Pizza Time can ensure that their SaaS implementation is secure, efficient, and aligned with their business objectives. They’re not just buying a service; they’re building a complete solution that empowers them to deliver the best possible experience to their customers. The key takeaway is that while a SaaS can provide a lot of functionality “out of the box,” it is still very important to build the right environment around the SaaS in order to make it successful.

Podcast

“Can I get Pizza Time as a podcast recording over in the right-hand panel? That was so fun. I already read it – I just want to hear it as your style of podcast, too, for my own delight. It can be short and sweet – this is just going to be my moment of zen. :)”

Okay, here is a short podcast-style recording of the Pizza Time example, drawing on information from the sources.

(Intro Music: Upbeat, jazzy tune with a hint of Italian flair)

Host: Welcome back to “Tech Talk Bites,” the podcast that breaks down complex tech concepts into easy-to-digest pieces. Today, we’re serving up a special episode – a case study, if you will – of how to build a thriving tech ecosystem around a SaaS, using a pizzeria called “Pizza Time” as our example.

(Short musical interlude)

Host: So, Pizza Time has just bought a SaaS platform to manage their online orders, delivery, and customer loyalty. That’s great, but as we’ve discussed before, buying a SaaS isn’t a “set it and forget it” situation. They still have to do a lot of “building” to make sure the SaaS works well for them. Let’s dig in.

(Sound of someone taking a bite of pizza)

Host: First, Pizza Time is treating their SaaS configuration like code. They’ve got a Git repository where they store all those important settings – the menu, prices, delivery zones, loyalty program rules. And with CI/CD pipelines using GitLab CI, any change is automatically pushed to their development environment, then staging, and finally production. This approach means that they always have consistent configurations everywhere.

(Sound of a cash register “cha-ching”)

Host: Next up, security. Pizza Time knows that passwords and API keys should never be hardcoded. They’re using HashiCorp Vault to manage all their secrets. Things like the delivery service API key and customer database passwords are stored and accessed securely from the vault. Their SaaS platform and CI/CD pipelines are configured to fetch those secrets when needed, keeping everything safe.

(Sound of a gentle “beep” like a timer)

Host: Now, how do they know everything’s working? Well, Pizza Time has set up synthetic monitoring probes. They’re using tools like Prometheus and Grafana to check the availability of their ordering page, API endpoints, and loyalty point system from different locations around the world. So, if there’s a problem, the operations team is notified right away.

(Sound of a keyboard)

Host: Testing is also a key part of Pizza Time’s tech strategy. They’ve got automated tests for a number of different things:

• Integration tests to make sure the payment gateway is working and that customer data is flowing to their delivery system.
• End-to-end tests that simulate a customer placing an entire order.
• Performance tests that put the system under heavy load to see how well it performs.
• And of course, security testing is integrated into their CI/CD pipeline, scanning for vulnerabilities in all configurations.

(Sound of a gentle “click” like a stamp)

Host: Pizza Time knows how important compliance is. As a business that handles payment information, they need to comply with the PCI DSS standards. They’ve set up an automated system to make sure all payment data is encrypted, access to customer data is secure, and reports can be generated automatically.

(Sound of a whoosh)

Host: You might be thinking, “All this work around a SaaS?” Well, Pizza Time is treating their infrastructure supporting the SaaS with the same level of care they would treat their own apps. They’re managing their monitoring systems and databases using Terraform. This ensures their infrastructure is configured consistently and can be easily rebuilt. They’re also using APM tools, infrastructure monitoring, and log aggregation to keep a close eye on their systems.

(Sound of someone picking up a phone)

Host: They’ve also integrated single sign-on (SSO) for employees and implemented data loss prevention (DLP) tools to keep everything secure. They’ve created documentation and training materials for their staff. And of course, they’ve also got a clear incident response plan that addresses potential issues.

(Sound of someone writing with a pen)

Host: And finally, Pizza Time is measuring their progress to ensure that the changes are having the desired impact. They’re tracking important metrics such as how their initiatives are mapped to business outcomes, the quantifiable impact of their changes on business metrics, their delivery times and stakeholder satisfaction. They’re also tracking the costs of the tools, and the security of their operations. All this work helps Pizza Time demonstrate that their SaaS implementation is secure, efficient, and aligned with their business goals.

(Outro Music: Upbeat, jazzy tune with a hint of Italian flair)

Host: So there you have it – Pizza Time. A great example of how even when you “buy,” you still need to “build” to create a successful SaaS ecosystem. They’re not just buying a service, they’re building a complete solution that empowers them to deliver the best possible experience to their customers. Thanks for tuning in to “Tech Talk Bites.” Until next time, happy tech-ing!

Pizza APM

“Tell me more about what might go into an APM at ‘Pizza Time.’”

Okay, let’s delve into what might go into Application Performance Monitoring (APM) at “Pizza Time,” drawing on the sources and our conversation history.

At Pizza Time, APM would be crucial for ensuring that their SaaS platform, which manages online orders, delivery, and customer loyalty, is performing optimally. The APM implementation would involve a combination of tools and practices aimed at tracking application performance, identifying bottlenecks, and improving end-user experience. Here’s a breakdown of what that might look like, based on the sources:

• APM Tools: Pizza Time would need to implement specific tools to monitor their application performance. These tools, like Prometheus and Grafana, would be used to track various metrics and create visualizations to help the operations team understand what is happening in the system.

• Key Metrics: The APM would focus on tracking specific metrics relevant to their operations:
  • Average Response Time: This metric would measure the time it takes for critical applications or services to respond to a request. For Pizza Time, this includes the response time of their ordering system, their delivery service API, and any other integration points that the SaaS might have.
  • Error Rates: This metric would track the number of errors occurring in the applications and services. For example, they would track the error rate for failed orders or failed API calls.
  • Throughput: This metric would monitor the number of requests or transactions processed by the application. Pizza Time would likely track the number of orders placed per minute, as well as the speed at which the delivery service is processing deliveries.
  • Database Performance: The APM would also need to monitor database performance, since a slow database could impact the overall performance of the application. This would include response time for database queries, as well as errors that might occur in the database layer.
• Monitoring Critical User Workflows: The APM would monitor critical user workflows to understand how end users are experiencing the system. For example:
  • Ordering Process: The APM would track how long it takes a customer to place an order, from browsing the menu to completing the purchase. This helps to ensure that the system is responsive and the user experience is smooth.
  • Delivery Tracking: The system would monitor how long it takes for delivery information to be updated and reflected in the system. This is essential for ensuring that the customers receive timely information about their delivery.
  • Loyalty Points System: The APM would monitor how quickly customer loyalty points are calculated, and how long it takes to award them to a customer. This is essential to ensure that the loyalty program is functioning as expected.
• Integration with other Tools: The APM tools would be integrated with other systems to provide a complete overview of the system:
  • CI/CD Pipeline: APM data would be integrated into the CI/CD pipeline so that the team can use the metrics to identify potential performance issues before deployment to production. This is useful to ensure that the team can roll back any changes that negatively impact performance.
  • Log Aggregation Tools: APM would be integrated with log aggregation tools to correlate performance issues with specific logs, which would assist the team in identifying the root causes of issues.
• Alerting and Notifications: APM would also include alerting systems to notify teams of critical issues. For example:
  • Response Time Thresholds: Alerts would be triggered if the average response time exceeds a certain threshold. This ensures that the team is notified when the performance of the system is degraded.
  • Error Rate Thresholds: If the error rate exceeds a specific limit, an alert is triggered. This helps to ensure that the team is notified of major issues as soon as they occur.
• Retroactive Metrics: In addition to real-time monitoring, Pizza Time would also use APM to collect retroactive metrics, querying their systems to establish a baseline, and tracking the impact of changes on their system over time:
  • Historical Performance Data: The team would be able to query their APM tools to track historical performance data such as the average response time and error rates for their applications over time.
  • Trend Analysis: This historical data would allow the team to see trends, such as changes in response times, errors, and throughput, so that they could identify potential issues or bottlenecks.
  • Impact of Changes: Pizza Time would be able to use retroactive metrics to measure the impact of changes they make to their systems. For example, the team could use the retroactive data to monitor the impact of changes in infrastructure on application performance.

By using APM, Pizza Time can proactively identify issues, optimize performance, and ensure a smooth and efficient experience for their customers, and also improve their delivery times and the efficiency of their operations. This is essential for maintaining customer satisfaction and for growing their business. The APM implementation would involve selecting the right tools, configuring them to track the correct metrics, and integrating them with other tools and systems to provide a complete overview of the performance of the system.

“Ooooooh, thank you. I thought you meant ‘Application Portfolio Management.’”

It sounds like there was a misunderstanding; you were thinking of “Application Portfolio Management” rather than “Application Performance Monitoring” (APM) [history]. It is understandable that you might have been thinking of Application Portfolio Management (APM), as both terms share the same acronym [history].

Here’s a breakdown of Application Performance Monitoring (APM) as it relates to DevOps and your sources:

• Purpose of APM: APM is crucial for tracking the performance of applications, identifying bottlenecks, and improving the end-user experience. It involves monitoring various metrics to ensure that applications are running smoothly and efficiently.
• Key APM Metrics: According to the sources, APM focuses on metrics including:
  • Average response time: This measures how long it takes for critical applications to respond to a request.
  • Error rates: This tracks the number of errors occurring in applications.
  • Throughput: This monitors the number of requests or transactions processed by the application.
• APM in a DevOps Context: APM is a key part of a DevOps strategy, as it helps teams to identify and resolve issues quickly, and also helps to optimize application performance.
• APM Tools: The sources mention tools like Prometheus and Grafana as examples of tools that are often used for APM.
• APM Implementation: Implementing APM involves selecting the right tools, configuring them to track the correct metrics, and integrating them with other systems.
• APM at “Pizza Time”: As discussed in our previous response, APM at “Pizza Time” would involve monitoring metrics such as the response time of the ordering system, the delivery service API, and the customer loyalty program [history]. It would also include monitoring critical user workflows such as ordering, delivery tracking and loyalty point calculations [history].
• Retroactive Metrics: APM tools also allow you to collect retroactive metrics by querying the historical data. This allows teams to see trends in application performance, and track the impact of any changes they make.
• Integration with CI/CD: APM data should be integrated with CI/CD pipelines, which helps teams to find issues before they are deployed to production, as well as enabling teams to roll back changes that negatively impact performance [history].

While both APM and Application Portfolio Management (which was not explicitly covered in your sources) relate to applications, APM is specifically focused on the real-time and historical monitoring of application performance and user experience, while Application Portfolio Management is concerned with the overall management and planning of an organization’s application assets. APM is a key part of a DevOps strategy that focuses on continuous improvement, and it helps to ensure that applications are meeting user expectations and business needs.

“Can you tell me more about what application portfolio management might look like at “Pizza Time”? I know it’s just a small restaurant and they wouldn’t realistically engage in such an endeavor, but please humor me – it’s a case study metaphor, I’m not actually opening up a pizzeria. ;)”

Okay, let’s explore what Application Portfolio Management (APM) might look like at “Pizza Time,” even though it’s a small restaurant and wouldn’t realistically engage in such an endeavor. This is a hypothetical case study to illustrate the concepts. It’s important to note that the sources provided do not directly discuss Application Portfolio Management (APM), and therefore, the following information is not explicitly drawn from the sources, but instead will be based on what is generally understood about APM. You may want to verify this information independently.

Here’s a breakdown of what APM might entail for Pizza Time:

• Purpose of Application Portfolio Management (APM): Unlike Application Performance Monitoring (APM), which focuses on the performance of individual applications, Application Portfolio Management is concerned with the strategic management of an organization’s entire suite of applications. It’s about making informed decisions regarding which applications to invest in, maintain, retire, or replace, based on their business value and alignment with strategic goals. For Pizza Time, this would involve understanding their technology landscape from a business perspective [history].

• Application Inventory: The first step would be to create a comprehensive inventory of all applications used at Pizza Time. This would include both the SaaS platform for online ordering and delivery, and any other applications they use, such as their point-of-sale (POS) system, accounting software, customer relationship management (CRM) tools, employee scheduling software, and inventory management systems. This provides a basis for the rest of the APM process.

• Business Value Assessment: Each application in the inventory would be assessed based on its business value. This would involve understanding how each application contributes to Pizza Time’s objectives, including:
  • Revenue generation: Does the application help to increase sales or improve the customer experience? For example, the online ordering platform directly contributes to revenue by facilitating online orders [history].
  • Cost reduction: Does the application help to reduce costs or improve efficiency? For example, employee scheduling software might help to reduce overstaffing.
  • Risk mitigation: Does the application help to reduce business risks, such as compliance with regulations? For example, the payment processing system would need to comply with PCI DSS standards.
  • Competitive advantage: Does the application give Pizza Time a competitive edge, such as improved customer experience or faster delivery? The customer loyalty program might help to retain customers and increase customer lifetime value.
• Technical Assessment: In addition to business value, each application would be assessed based on its technical characteristics:
  • Technical fit: Is the technology still current, and does it align with Pizza Time’s technology strategy?
  • Reliability: Is the application stable, reliable, and performing as expected? This could be evaluated based on historical data and error rates from APM [history].
  • Maintainability: Is the application easy to maintain and update? This can help to understand how easy it will be to fix any issues that occur in the application.
  • Scalability: Can the application scale to meet the needs of a growing business? It is important to consider how easily the application can scale with a larger number of customers, or in new geographical locations.
  • Security: Are there any security risks or vulnerabilities in the application? This helps to ensure that security is a priority when selecting applications.
  • Cost: What is the cost of running the application, including the cost of the SaaS platform itself, licenses, and support services?
• Application Rationalization: Based on the business value and technical assessments, Pizza Time would make decisions about which applications to:
  • Invest: Applications that are crucial to the business and have high value would be prioritized for continued investment. For Pizza Time, the online ordering platform and the delivery system would likely be in this category.
  • Maintain: Applications that are needed but not a high priority might be maintained at current levels of investment.
  • Retire: Applications that are no longer needed or have low business value might be retired.
  • Replace: Applications that are technically outdated or have better alternatives might be replaced with new solutions.

• Roadmaps: The APM process would also inform the creation of roadmaps that prioritize technology investments and improvements for Pizza Time, focusing on the areas where technology can drive the most value, such as the online ordering system, delivery service, and loyalty program. This helps to ensure that the team is focusing on the right areas. The roadmaps would include selecting and implementing new tools, and creating a plan for implementing CI/CD.

• Ongoing Review: APM is an ongoing process, so Pizza Time would regularly review and update their application portfolio to ensure it is aligned with business needs and technological advancements. This also helps to ensure that the team is using the right tools for the job, and helps to make sure that the technology portfolio is up-to-date.

• Metrics for APM: Pizza Time would measure the effectiveness of its APM strategy, including:
  • The number of applications mapped to business outcomes: This would show the alignment of the application portfolio with the business goals.
  • The quantifiable impact of the applications on business metrics: This would show how much value is being derived from the applications used in the organization.
  • Stakeholder satisfaction with the applications: This would show whether the applications are meeting stakeholder needs.
  • The overall cost of the application portfolio: This would show the cost of maintaining and supporting the overall technology portfolio, and help to determine if it is aligned with the business value.

In the context of a small pizzeria like “Pizza Time,” this level of strategic application portfolio management is not typical but serves as a useful metaphor for understanding the importance of aligning technology decisions with business objectives. While a small business might not need a fully formalized APM process, the underlying principles of understanding application value, technical fit, and strategic alignment are relevant to any business using technology to improve their operations. For a larger organization, a formal APM process would be essential to managing the application portfolio strategically.

“Would an Application Portfolio Management tracking system also include any details about how to integrate all of Pizza Time’s various applications into each other? Like notes about which ones can/do talk to which others, and which ones can’t/don’t?”

While the sources don’t explicitly detail how an Application Portfolio Management (APM) system would track application integrations, it’s logical to infer that such a system would include details about how the various applications interact with each other [history]. This is a crucial aspect of understanding the overall technology landscape of an organization, and is an important consideration when making decisions about which applications to invest in, maintain, or retire [history].

Here’s how an APM system might include integration details, drawing from our conversation history and general understanding of APM:

• Application Inventory: An APM system would start with a comprehensive inventory of all applications used by “Pizza Time” [history]. This inventory would not only list the applications, but would also include details about each application’s purpose, function, and how it interacts with other applications.
• Integration Mapping: The APM system would likely include a visual representation or map of how the different applications connect with each other [history]. This could take the form of a diagram or a database with structured information. This mapping would detail:
  • Data flows: Which applications exchange data with each other? For example, the online ordering platform sends customer order information to the delivery management system [history].
  • API integrations: Which applications use APIs to connect with each other? For example, the online ordering platform may use the payment gateway API to process payments [history].
  • Direct integrations: Which applications have direct integrations with each other, and what data or services are exchanged? For example, the customer loyalty program might have a direct integration with the POS system to track customer purchases.
  • Indirect integrations: Which applications have indirect connections with each other? For example, the scheduling application may provide the employee information to the POS and delivery tracking systems.
• Integration Documentation: The system would likely contain documentation of the different integrations, including notes about:
  • Integration type: Details about the specific type of integration, such as API, database connection, or message queue.
  • Data formats: Information about the data formats used for integration, such as JSON, XML, or CSV.
  • Security considerations: Notes about any security protocols or considerations relevant to the integration such as authentication and authorization mechanisms.
  • Limitations: Any limitations or constraints of the integration.
• Integration Status: The APM system could also include information on the status of each integration, such as whether it is:
  • Active: An integration that is currently working as expected.
  • Under development: An integration that is currently being developed.
  • Problematic: An integration that is experiencing issues.
  • Deprecated: An integration that is no longer in use.
• Dependencies: The APM system could also track application dependencies, to show how applications depend on each other to function. For example, the delivery service application may depend on the customer data from the online ordering application.
• Technical Assessments: As part of a technical assessment, the APM would assess the health, reliability, and maintainability of the application integrations.
• Rationalization Insights: The integration information would help with application rationalization decisions [history]. For example:
  • If several applications have overlapping functionality, and are difficult to integrate, then some applications may be candidates for retirement.
  • If a crucial business application depends on an old and unreliable application, it might be a candidate for replacement.
  • If applications are easy to integrate and interact well with each other, they are likely to remain in the portfolio.
• Roadmap Planning: The integration information would inform strategic decisions about technology investments and improvements [history]. For example, an organization might choose to:
  • Prioritize investments that enhance integrations between key applications
  • Upgrade or replace outdated applications that create integration problems
  • Standardize integration protocols to reduce complexity and improve interoperability

In essence, an APM system would strive to provide a holistic view of the application landscape, not just a list of applications. It would highlight the connections and dependencies, enabling more informed decision-making about technology investments, upgrades, and retirements [history]. This would help to ensure that the applications are aligned with business goals, and to manage risks and costs effectively. For “Pizza Time,” this would mean a better understanding of how their online ordering system, delivery tracking, and customer loyalty programs connect, and how to make these integrations more efficient and effective.

“What if a lot of your examples #1-12 were protected behind employee/customer SSO? How do we spec out appropriate ways to test those endpoints (if applicable – don’t bother putting things behind authentication & authorization that would likely be unauthenticated in the real world).”

When many of the API endpoints are protected behind employee or customer SSO (Single Sign-On), synthetic monitoring probes need to be configured to handle the authentication and authorization requirements. Here’s how to specify appropriate testing methods for those endpoints, drawing from the sources and our conversation history:

Authentication and Authorization Considerations

• Simulating User Logins: For endpoints protected by SSO, the synthetic monitoring probes must simulate the login process. This often involves more than a simple HTTP request.
• Token Management: Once authenticated, the probe will need to manage authentication tokens (e.g., JWT, OAuth tokens) and include them in subsequent requests. This requires a system to store and update those tokens.
• Test Users and Credentials: You’ll need to create test user accounts for both employees and customers that are specifically for monitoring purposes. It is important to keep these test credentials secure, and to ensure they are not used for purposes other than testing.
• Varying Roles and Permissions: If the endpoints have different behavior based on user roles or permissions, you may need multiple probes to test different user contexts. For example, you might need a test user with “admin” privileges, and another with “customer” privileges, to be sure all cases are being covered.

Modifying Probe Specifications

Here are modifications to the example probes to accommodate SSO:

• Probe 6: Menu API Availability

  • Scenario: If the menu API requires authentication for employee access:
    • URL to Monitor: https://api.pizzatime.com/menu
    • Authentication:
      • Login Step: Include a login step where the probe sends a request to the authentication endpoint with the test user’s credentials (username and password). The probe will need to store the resulting token.
      • Token Inclusion: The probe will then include the token in the Authorization header (e.g. Authorization: Bearer <token>) in the request to the menu API.
    • Expected HTTP Response Code: 200
    • Request Headers: Content-Type: application/json, Authorization: Bearer <token>
    • Request Body: None
    • Monitoring Frequency: Every 15 minutes
    • Alerting Thresholds: Response time above 750ms, or 3 consecutive failures, or if the response code is not 200.
    • Team(s) to Notify: Operations Team, Backend Development Team.
    • Notes: This probe ensures that the menu data is available for employee access and that the SSO integration is working correctly. The probes should handle the token refresh process as part of their authentication flow to prevent expiry.

• Probe 7: Delivery Zone Lookup API

  • Scenario: If this endpoint requires customer authentication:
    • URL to Monitor: https://api.pizzatime.com/delivery/zones?zip_code=12345

Key Considerations for SSO

• Token Refresh: The probes will need to handle token expiration and implement a token refresh process. The probes should be able to get a new token before the existing token expires.
• Security: It’s crucial that test user credentials and authentication tokens are stored and managed securely, and not hardcoded into the probes.
• Complexity: Handling SSO adds complexity to the monitoring setup. The monitoring system should support these flows, and the probes need to be configured appropriately.
• Tooling: The tools used for synthetic monitoring must be capable of handling the authentication and authorization flows required by your system, including OAuth, SAML, or other SSO methods.
• Error Handling: The probes need to handle authentication failures gracefully and report them as issues.

By implementing these changes, you can ensure that your synthetic monitoring probes provide an accurate reflection of your system’s performance and availability, even when many endpoints are protected by SSO. This ensures that your monitoring is closely aligned with the real user experience and that any issues are detected promptly.

Splunk workload identities in Entra

https://www.google.com/search?client=firefox-b-1-d&q=entra+workload+id+for+splunk

A “Microsoft Entra Workload ID for Splunk” refers to the integration of Microsoft Entra ID (formerly Azure Active Directory) with Splunk, allowing Splunk to utilize “Workload Identities” - essentially identities for applications and services - to securely access cloud resources within Microsoft Azure, enabling authentication and authorization for non-human entities within your Splunk environment. 

Key points about Entra Workload ID in Splunk:

• Secure Access: By using Workload Identities, Splunk applications can access Azure services without requiring traditional user credentials, enhancing security. 

• Application Authentication: You can configure Splunk applications to use their own Workload Identities to authenticate with Azure services like storage, databases, and APIs. 

• Management in Azure Portal: You manage and control these Workload Identities within the Microsoft Entra admin center, defining access policies and permissions. 

• Integration Method: To set up this integration, you typically need to create a “SAML application” within Microsoft Entra ID and configure Splunk to use it for authentication.

CI/CD telemetry and friends

“Let’s dive into Pizza Time’s CI/CD system. Looking at https://opentelemetry.io/docs/specs/semconv/cicd/cicd-metrics/, it seems that it’s important to collect each CI/CD pipeline run’s name, state, result, duration, and error type (if it errored out). Into which type of system should I dump this data? What other logging/monitoring/observability data would you, as the business owner, also hope is available in that system into which we’re dumping such data?”

Based on the provided sources, here’s a breakdown of where to store CI/CD pipeline data and what other related information would be valuable for monitoring and observability, especially for a business like Pizza Time:

Where to Dump CI/CD Pipeline Data

• Monitoring and Observability Tools: The sources suggest using tools like Prometheus, Grafana, ELK stack, or Splunk for monitoring and observability. These tools are well-suited for handling time-series data, like the metrics you want to collect about your CI/CD pipelines.
  • Specifically, the OpenTelemetry semantic conventions for CICD metrics define several key metrics that are recommended for collection. These include cicd.pipeline.run.duration, cicd.pipeline.run.active, cicd.worker.count, cicd.pipeline.run.errors, and cicd.system.errors.
  • These metrics can be used to track the health and performance of the CI/CD system, and can be tied to alerts and notifications.
  • The cicd.pipeline.run.duration metric tracks the duration of a pipeline run, grouped by pipeline name, state, and result. This includes the error type, if the pipeline run failed. The cicd.pipeline.run.active metric tracks the number of pipeline runs currently active in the system by state. The cicd.worker.count metric tracks the number of workers on the CICD system by state. The cicd.pipeline.run.errors metric tracks the number of errors encountered in pipeline runs. The cicd.system.errors tracks the number of errors in a component of the CICD system.
  • It is important to note that the error.type attribute should be predictable, and should have low cardinality. It can be set to a canonical class name when an exception occurs. A set of well-known values are described in the source.
• Centralized Logging System: A centralized logging system (like the ELK stack) is essential for collecting and analyzing log data from various sources. This system should collect not only the structured metric data mentioned above, but also the raw log output from the CI/CD system. This will allow for more detailed analysis, and for the creation of alerts.

Additional Logging/Monitoring/Observability Data

As a business owner, in addition to the core CI/CD pipeline data, you would want to have the following types of data available in your observability system:

• Application Performance Metrics (APM):
  • Average response time: Monitor average response times for critical applications. This is critical for ensuring a good user experience, and might include things like how long it takes to load Pizza Time’s ordering page.
  • Error rates: Track error rates for applications. This will help to identify application issues.
  • Throughput: Monitor the number of requests or transactions processed by the application. A high throughput means better efficiency.

“If you owned Pizza Time, what are the top 5 queries you would ask an engineer to run for you against the data in whichever time-series-data-handling observability tool Pizza Time chose?”

If I owned Pizza Time, here are the top 5 queries I would ask an engineer to run against the data in our time-series observability tool, drawing from the sources and our conversation history, to give me the most actionable insights about our business:

1. “What is our deployment frequency and lead time for changes, and how are these trending over time?”
   • This combines two key metrics that provide a high-level understanding of our software delivery process. Deployment frequency tells us how often we’re releasing changes. Lead time for changes measures the time it takes to deliver a change to production.
   • By tracking these metrics over time, we can assess whether our DevOps practices are improving our agility and ability to deliver value to customers.
   • A decrease in lead time and an increase in deployment frequency would indicate that we are becoming more efficient in our software delivery.
   • According to the sources, these are key high-level metrics that are easily measured retroactively and provide a broad understanding of the effectiveness of our DevOps practices.
   • The data can be gathered from deployment logs, release management tools, version control systems, or work management systems.
2. “What is the average duration of our CI/CD pipeline runs, and what are the most common error types?”
   • This query focuses on the efficiency and reliability of our CI/CD pipelines.
   • The cicd.pipeline.run.duration metric, as described in the OpenTelemetry semantic conventions, tracks the duration of a pipeline run, grouped by pipeline name, state, and result.
   • Knowing the average duration can help us to identify bottlenecks in our pipelines, and to focus our efforts to reduce the overall time taken to deliver changes.
   • By examining the error.type attribute, we can also see the most common causes of pipeline failures.
   • This information is readily available in CI/CD tools such as Jenkins, GitLab CI or GitHub Actions.
   • The source also notes that the error.type should have a low cardinality and be predictable, to assist in creating useful queries.
   • The cicd.pipeline.run.errors and cicd.system.errors metrics can also provide additional insights into how errors are impacting the CI/CD system.
3. “What are the average response times and error rates for our key applications, and how are these trending over the last week, especially during peak hours?”
   • This query is focused on the customer experience.
   • Average response time for critical applications directly impacts the user experience. Slow response times mean customers will be more likely to abandon their orders.
   • Error rates for applications are also critical, as they indicate the reliability of our systems.
   • By tracking these metrics over time, and especially during peak hours (e.g. lunch and dinner rushes), we can identify and address any issues that are impacting our customers at our busiest times.
   • This data can be obtained from Application Performance Monitoring (APM) tools such as Prometheus or Grafana.
   • The sources emphasize the importance of monitoring for application performance, and of optimizing response times to improve user experience.
4. “What is our test pass rate, test cycle time, and percentage of tests automated, and how do these trend over time?”
   • This query focuses on the quality of our software, and our ability to deliver changes quickly.
   • Test pass rate tells us how reliable our builds are, and how confident we should be in the quality of our code. A higher pass rate means more confidence in the quality of the build.
   • Test cycle time measures how quickly we can run our automated tests, so a shorter cycle time means faster feedback.
   • Percentage of tests automated tells us how much of our testing is automated, and where we might want to automate more of our testing. Increased automation means faster feedback, and greater confidence in builds.
   • By monitoring these metrics over time, we can ensure that we are continuously improving the reliability and speed of our testing process.
   • This information is available from our CI/CD system, as the sources note that these are key metrics that should be tracked.
5. “What is the number of open pull requests, and how long have they been open?”
   • This query is intended to provide insights into our development workflow and identify potential bottlenecks in our code review process.
   • By looking at the number of open pull requests, we can understand how much work is awaiting review. A large number of open pull requests may indicate that our developers are not able to get their code merged quickly enough.
   • By tracking how long pull requests have been open, we can determine if code reviews are causing a bottleneck, or if we have any pull requests that have been open for an unexpectedly long amount of time.
   • The vcs.change.count metric tracks the number of changes (pull requests/merge requests/changelists) by their state (e.g. open), and the vcs.change.duration metric tracks how long these changes have been in a given state.
   • The vcs.change.time_to_approval and vcs.change.time_to_merge metrics provide additional insights into how long pull requests take to be approved and merged.
   • This data is available in our version control system.

These five queries provide a good balance between high-level business metrics, CI/CD pipeline performance, application reliability and customer experience, as well as insights into our development workflow. By regularly monitoring these metrics, I would be able to make informed decisions about how to improve our processes, enhance the customer experience, and drive the success of Pizza Time.

“Those were great, thanks. Feel free to add more, please, if you think 5 wasn’t quite enough to hit what an owner REALLY cares about. (Or just tell me you’re done, if 5 was perfect.)”

Okay, here are some additional queries that a business owner might care about, expanding on the previous five and drawing from the sources and our conversation history, and using bold to highlight the most important parts:

• “What is the percentage of our infrastructure that is managed as code, and how does this trend over time?”
  • This metric focuses on the consistency and repeatability of infrastructure management, which is important for stability and scalability.

More helpdesk articles

This is awesome! That said, it’s kind of aimed more at a CTO than the pizzeria’s owner, but I know that you know I’m a technical person, so thanks for being an imaginary “tech-savvy owner” for the previous exercises – it definitely helped me.

However, now I need help taking what I’ve learned today and breaking it up into helpdesk articles aimed at different audiences.

The pizzeria’s owner (who only knows how to run a restaurant) is analogous to an enterprise department’s director, in my case. And the pizzeria’s CTO/”tech-savvy owner” is analogous to that same enterprise department’s embedded IT team.

I need to write at least 2 helpdesk articles.

The first one is basically, “Congrats – you bought a SaaS!” as we did before, but really, really, really aimed at owning a pizzeria (a true owner who just knows how to run a restaurant).

And then it should have a lot of “talk to your tech team about __, and when you do, be sure to have them see __(TECHNICAL ARTICLE TITLE OR TECHNICAL ARTICLE’S SECTION TITLE HERE) for context” types of cross-references.

The second+ one(s): the “see here” content that can help everyone across a variety of technical skill levels and types within the pizzeria’s (or, analogously, enterprise department’s) embedded IT team (from business analysts to product owners to CTOs to junior developers to senior developers to QAs – while detailed plain-English specifications and templates are okay, the tone should be kept so that no one gets confused or overwhelmed) can have productive conversations about the requests they get from the pizzeria’s actual owner (or, analogously, the enterprise department’s director).

Okay, here are two helpdesk articles tailored for different audiences within a pizzeria (and analogously, an enterprise department), drawing from the sources and our conversation history. The first is aimed at the pizzeria owner, and the second provides technical context for the IT team.

Version control for SaaS configurations

“Are we sure that we want to use version control to track changes to menu items, prices, and descriptions? Doesn’t that essentially involve having to rebuild a data store in version control that was the whole point of buying a SaaS to data-enter into?”

While it might seem counterintuitive to use version control for tracking changes to menu items, prices, and descriptions in a SaaS, there are several reasons why this approach can be beneficial, despite the fact that the SaaS itself also manages that data:

• Configuration Management: The sources emphasize the importance of managing SaaS configurations with version control and CI/CD pipelines. Using version control for menu items, prices, and descriptions allows the organization to treat these as configurations, enabling consistent and repeatable deployments across different SaaS environments. This provides a level of control and repeatability that is vital for stability and reliability.
• Auditability and History: By storing changes to menu items, prices, and descriptions in a version control system like Git, an organization can easily track who made what changes and when. This creates an auditable history, making it easy to revert to a previous state if necessary, or to review changes for compliance reasons.
• Collaboration: Storing SaaS configurations in version control facilitates collaboration amongst team members. Multiple individuals can work on different aspects of the menu, prices or descriptions concurrently, and changes can be reviewed and merged, with a clear history of who made which changes.
• Automated Deployments: With configurations in version control, changes can be deployed automatically using CI/CD pipelines. This ensures that updates to the menu, pricing or descriptions are deployed consistently across all environments, reducing the risk of manual errors. For example, the sources describe a pizzeria using CI/CD pipelines to automatically update a development instance of their SaaS when changes are pushed to a Git repository, followed by updates to the staging and production environments.
• Disaster Recovery: In case of an issue with the SaaS vendor, having a copy of the configurations in version control provides a backup. Although, this is not a complete backup of all data in the SaaS, as the SaaS data store itself would have its own backup procedure, a backup of configurations would allow an organization to recreate or reconfigure the SaaS based on a known, working configuration if needed.
• Testability: Having menu items and prices in version control allows for automated testing as part of the CI/CD pipeline. For example, tests can be written to ensure that changes to the menu, pricing or descriptions are properly reflected in the application, and are not breaking other functionality.

While using version control for configurations may seem like rebuilding a data store, the primary goal is not to duplicate the SaaS database, but rather to manage the SaaS’s configuration in a controlled and repeatable manner. Using version control in this way provides benefits such as audibility, collaboration, consistent deployments, and disaster recovery.

It is also worth noting that you can use retroactive metrics to track changes over time, and these metrics can include deployment frequency, build frequency, and build success rate. You may want to consider metrics specific to SaaS integrations such as business value mapping and lead time of value delivery. You may also want to track the cost of the tools and stakeholder satisfaction. These types of metrics can help measure the impact of your decision to track SaaS configurations in version control over time.

Data versioning discernment (“categorizing Pizza Time’s SaaS data”)

Can you write me a helpdesk article that walks me, a member of Pizza Time’s technical team, through categorizing various types of data that would likely be in a pizzeria’s SaaS into the following 3 types of category (if applicable):

1. “just consider it content-data that’s merely part of the production database; don’t even bother to track it with Git”
2. “consider it content-data that’s merely part of the production database, but still track changes to it in Git”
3. “consider it configuration-data for which the primary source of truth should be Git; never touch it using the SaaS’s administrative UI; always only set it via CI/CD”

Okay, here’s a helpdesk article to guide you, a member of Pizza Time’s technical team, in categorizing data within your pizzeria’s SaaS, based on our previous conversations and the provided sources:

Categorizing Data in Pizza Time’s SaaS: A Guide for Technical Teams

As we integrate our new SaaS platform, it’s essential to understand how to manage the different types of data it involves. This article will help you categorize data into three distinct categories, each with its own management approach. These categories will help us determine which data to track using version control and which data to manage directly within the SaaS.

Understanding the Categories

Before we dive in, here’s an overview of the three data categories:

1. Content-Data (Do Not Track in Git): Data that is primarily part of the production database and doesn’t require version control. It’s managed directly through the SaaS interface and is generally user-generated content.
2. Content-Data (Track Changes in Git): Data that is also part of the production database, but changes to it should be tracked in version control for auditability, collaboration, and automated deployment.
3. Configuration-Data (Git as Source of Truth): Data that configures the SaaS and should be managed primarily via Git and CI/CD pipelines, with the SaaS interface being used rarely, if ever, to make changes to it.

Categorizing Pizza Time’s SaaS Data

Let’s look at how we might categorize different types of data within Pizza Time’s SaaS:

1. “Just consider it content-data that’s merely part of the production database; don’t even bother to track it with Git”

   • Customer Orders: The details of individual customer orders, including items ordered, delivery address, time, and payment information. This is transaction data that is generated by customers and not used to configure the system itself. This type of data should be managed directly within the SaaS.

   • Customer Reviews and Ratings: Feedback left by customers on orders and overall experience. This is user-generated content, and therefore, should not be tracked in Git.

   • Real-time Delivery Driver Locations: Locations of drivers should not be tracked in git as this is volatile data that changes frequently, and is managed by a separate driver application that is integrated with the SaaS.

2. “Consider it content-data that’s merely part of the production database, but still track changes to it in Git”

   • Menu Items: This includes the names, descriptions, ingredients, and prices of menu items. While it might seem like regular content, changes to menu items and prices are business critical, and need to be tracked for consistency and auditability. The sources suggest that all changes to the menu, including the addition of a new “Spicy Pineapple” pizza or seasonal price adjustments, can be tracked in version control.

   • Delivery Zones: The geographic areas that Pizza Time delivers to, including the associated zip codes or postal codes, need to be stored in version control, as changes to this information must be carefully tracked and auditable.

   • Loyalty Program Rules: The details of the loyalty program, including points awarded per purchase or special offers for repeat customers. These are also configurations, that should be tracked in version control.

   • Store Hours: The times when the store is open for delivery and pickup. While this is displayed to customers, these are considered core configurations that need to be managed carefully.

3. “Consider it configuration-data for which the primary source of truth should be Git; never touch it using the SaaS’s administrative UI; always only set it via CI/CD”

   • API Keys and Secrets: API keys for integrated services (e.g., payment gateways, delivery services) should be stored in a secrets management tool, and only accessed via the CI/CD pipeline, never through the SaaS’s administrative UI. The sources note the need for a robust secrets management tool to prevent sensitive information from being hardcoded into applications.

   • SaaS Configuration Settings: Specific configurations related to SaaS behaviors, such as the settings that control the UI appearance, order processing workflows, and customer notifications. These should be stored in Git and managed via CI/CD to ensure consistency. The sources note that CI/CD is crucial for consistent and automated deployments.

   • Synthetic Monitoring Probes: Definitions for monitoring probes, including target URLs, request headers, and expected response codes, should be managed as code, using version control. The sources emphasize the importance of monitoring and observability.

   • CI/CD pipeline configurations: Configuration of our CI/CD pipeline itself should be tracked in version control. The pipeline’s configuration, such as the steps that execute for builds and deploys, should be tracked like other infrastructure as code.

Why Categorize Data?

Categorizing data helps to manage it more effectively:

• Consistency: Configuration data that is managed via Git ensures that all instances of the SaaS are configured in a consistent and repeatable way.
• Auditability: Tracking changes to content and configurations in Git provides an audit trail, allowing us to see who made changes and when.
• Automation: Managing configuration and content via CI/CD allows for automated deployments, reducing manual effort and potential for errors.
• Security: Storing secrets outside of the SaaS in a secure location prevents sensitive information from being exposed.

Implementation

• Version Control: Use Git to store all content and configuration data that we want to track. All changes must be committed to version control.
• CI/CD: Use CI/CD pipelines to deploy changes to configurations and content to various environments (dev, staging, production).
• Secrets Management: Use tools like HashiCorp Vault to securely store and manage secrets. Access secrets through CI/CD pipelines, not directly through the SaaS administrative UI.
• Training: Ensure that all team members are trained on how to work with these data categories and tools.

By adhering to this categorization and management approach, we can ensure that our SaaS implementation is secure, efficient, and aligned with our business objectives. This approach will also improve our ability to track changes to data over time, and provide a better history of the changes made to the system, as well as improve the consistency of our deployments.

Key Takeaway

Remember, the key is to treat the SaaS as a component of our overall system, with different data types requiring different management strategies. By being intentional about how we manage data, we can ensure a stable and successful SaaS implementation.

Let me know if you have any other questions.

Absolutely stunning. You nailed it. Also, it’s interesting – the breakdown of data reminds me a lot of the way I’ve been taught to break apart data into concepts like “put it into the application’s transaction database,” “put it into the application’s configuration parameter and feature flagging system,” and “put it into the application’s config files within source code.” Very rate-of-change driven.

“Data management strategies for SaaS applications”

The data categorization presented in the helpdesk article does indeed align with concepts often used in application development, such as separating transaction data, configuration parameters, and source code configurations [history]. This alignment is rooted in the principle of managing data based on its rate of change and purpose [history].

Here’s how the categories relate to those concepts, and how the sources support this idea:

• Content-Data (Do Not Track in Git): This category corresponds to the transactional data that is typically stored in an application’s production database [history].

  • This data is highly volatile, changing frequently based on user actions [history].
  • Examples such as customer orders, reviews, and driver locations reflect real-time interactions and user-generated content.
  • The sources do not recommend tracking this type of data in version control due to its high rate of change and its nature as user-generated information [history].

• Content-Data (Track Changes in Git): This category represents data that while residing in the production database, is less volatile and more akin to application content that needs careful management and tracking [history].

  • This data is often used to define the core features and offerings of the application such as menu items, delivery zones, and loyalty program rules, and has a slower rate of change compared to transaction data, but changes to it still must be tracked [history].
  • The sources emphasize that while this data may be part of the application’s data, tracking changes in version control provides auditability, collaboration, and automated deployment capabilities [history].
  • The sources also note that this data needs to be tracked because changes are often business critical [history].

• Configuration-Data (Git as Source of Truth): This category aligns with the concept of configuration parameters and source code configurations that are critical to the application’s functionality [history].

  • This type of data changes relatively infrequently, but it directly impacts the behavior of the application and the SaaS [history].
  • Examples such as API keys, SaaS settings, and monitoring probes require strict version control and management via CI/CD pipelines to ensure consistency and security.
  • The sources state that managing configuration data through Git and CI/CD ensures consistent deployments across all environments and prevents sensitive data from being exposed [history].
  • These configurations should be managed via infrastructure as code as much as possible, so that the configuration of the system can be automatically reproduced [history].

Rate-of-Change Driven Approach:

• The categorization is indeed driven by the rate of change of the data [history].
  • High rate of change data, such as transactional data, is managed directly within the SaaS without version control.
  • Moderate rate of change data, such as menu items, delivery zones, and loyalty program rules, is tracked in Git for version control, auditability, and controlled updates.
  • Low rate of change data, like API keys and SaaS settings, is managed strictly via Git and CI/CD.
• This rate-of-change driven approach helps ensure the correct level of control, audibility, and automation for each type of data.

Analogy to Traditional Application Development

• The data categorization mirrors the way data is managed in traditional application development:
  • Transactional data goes into the database.
  • Application parameters and feature flags become configurations that are tracked in Git.
  • Source code configuration files are always managed in Git.

Key Takeaways

• The sources emphasize the need to manage different types of data differently based on their characteristics, including rate of change.
• This approach ensures consistency, audibility, security, and efficiency in managing the SaaS platform, and aligns with best practices for both SaaS and traditional application development.
• This intentional and rate-of-change driven approach will help Pizza Time to ensure a stable and successful SaaS implementation.

By recognizing the parallels between how data is managed in a SaaS environment and traditional application development, Pizza Time’s technical team can apply their existing knowledge and experience to manage the new SaaS platform effectively.

DevOps Metrics and Best Practices

1. How does aligning DevOps practices with business objectives benefit an organization?

Aligning DevOps with business objectives ensures that technical efforts directly contribute to key business outcomes, such as increased revenue, reduced costs, and improved customer satisfaction. By mapping DevOps initiatives to specific business goals, organizations can prioritize their efforts more effectively, improve stakeholder alignment, integrate feedback into the DevOps process, and optimize the overall value stream. For example, if faster delivery of new menu items is a business objective for “Pizza Time,” DevOps can focus on optimizing the CI/CD pipeline and automate testing, and track lead time for changes as a direct metric of success. This ensures the technical team is working on what is most valuable to the company.

2. What is a phased plan for DevOps implementation, and why is it important?

A phased plan involves implementing DevOps practices gradually across an organization. It typically includes pilot projects, incremental implementation, training, and iterative refinement, accompanied by a thorough communication plan. This approach is important because it allows organizations to test and refine practices in a controlled environment, minimize disruption, and ensure a smooth transition to DevOps. For example, a phased approach to CI/CD at “Pizza Time” might involve starting with the ordering API before moving to other components, and measuring success rate of pilot projects to ensure the team is ready for the next phase. This reduces risk, and allows for continuous improvements.

3. What are some key metrics for measuring the success of a DevOps culture?

Key metrics for measuring a DevOps culture include team satisfaction scores, to measure the level of collaboration, frequency of cross-functional team meetings, to measure communication, adoption rate of shared tools, to measure collaboration, and frequency of feedback cycles, to measure continuous improvement. Tracking how many conflicts are resolved constructively is also important to measure psychological safety. These metrics help assess how effectively teams are collaborating, communicating, and driving a culture of continuous improvement. For example, if “Pizza Time” is struggling with inter-team communication, tracking frequency of cross-functional team meetings can help to address this issue. A good DevOps culture also promotes a blameless culture, where mistakes are seen as learning opportunities.

4. How do continuous integration and continuous delivery (CI/CD) practices contribute to overall DevOps efficiency?

CI/CD practices automate the process of building, testing, and deploying software changes, resulting in faster, more reliable releases. CI/CD pipelines consist of automated build processes, version control management, automated deployment pipelines, infrastructure as code, and test automation. Metrics include build frequency, build success rate, deployment frequency, and lead time for changes. These metrics enable organizations to release software more rapidly, reduce errors, and improve overall agility. For example, if “Pizza Time” can deploy changes faster thanks to CI/CD, then lead time for changes should reduce, and this metric can measure the efficiency gains.

5. What role does monitoring and observability play in DevOps?

Monitoring and observability are crucial for identifying performance issues, optimizing applications, and ensuring a good end-user experience. This involves implementing Application Performance Monitoring (APM) tools, infrastructure monitoring, log aggregation and analysis, and alerting systems. Metrics like average response time, error rates, CPU and memory utilization, and network latency are essential for understanding system performance and identifying potential bottlenecks. “Pizza Time” uses average response time to make sure their online ordering system is always performing at peak efficiency. The goal is to quickly identify issues before they impact customers.

6. Why is security tooling a necessary component of a DevOps roadmap?

Security tooling integrates security into the DevOps pipeline, ensuring that applications and infrastructure are secure. This includes Static Application Security Testing (SAST), Dynamic Application Security Testing (DAST), Software Composition Analysis (SCA), secrets management, and vulnerability scanning. Metrics include the percentage of builds with automated security testing, the number of vulnerabilities identified, and the time to remediate vulnerabilities. These practices prevent security issues from being deployed into production, thereby reducing risk. “Pizza Time” uses percentage of builds with automated security testing to ensure that every software release has been security tested.

7. How do version control system (VCS) metrics provide insight into software development?

VCS metrics like vcs.change.count, vcs.change.duration, vcs.change.time_to_approval, and vcs.change.time_to_merge offer insights into developer activity and workflow efficiency. These metrics help track code changes, identify bottlenecks in the development process, and measure collaboration and code review effectiveness. A high vcs.change.count might indicate high developer activity, but a long vcs.change.time_to_merge might signal a bottleneck in the review process.

8. What technical metrics can be measured retroactively to understand system performance and identify areas for improvement?

Technical metrics that can be measured retroactively by querying existing data include deployment frequency, build frequency, build success rate, build time, percentage of infrastructure managed as code, average response time, error rates, CPU and memory utilization, disk usage and IO, and network latency. These metrics provide a baseline understanding of current system performance, highlight potential issues, and help assess the effectiveness of implemented improvements. For instance, “Pizza Time” could measure build time to identify performance improvements.
