Metrics for measuring CI/CD and automated deployments include: Build time: the time it takes for an application to be built and deployed Deployment frequency: the number of times an application is deployed in a specific time period Deployment failure rate: the number of failed deployments versus the total number of deployments Proportion of change failure rate: The ratio of the number of deployments that resulted in failures or errors to the total number of deployments Code coverage: The percentage of code that was executed with automated tests Mean time to failure: The average time between failure occurrence and resolution Lead time: Code submission to deployment to Average time required for production environment

Metrics for PHP CI/CD and automated deployment

Continuous Integration (CI) and Continuous delivery (CD) is an indispensable practice in modern software development. They enable teams to deliver software faster and more reliably. It is important to measure the efficiency and effectiveness of your CI/CD and automated deployment processes, here are some key metrics:

Build Time: Build time measures building the application and deploying it to testing or Time required for production environment. Shorter build times indicate a more efficient process.

Deployment Frequency: Deployment Frequency measures the number of times a team deploys an application during a specific time period. Higher deployment frequency indicates more frequent updates and reduces time to market for new features and fixes.

Deployment failure rate: The deployment failure rate measures the number of deployments that failed during a deployment compared to the total number of deployments. Lower deployment failure rates indicate a more stable process and improved deployment success rates.

Change Failure Rate: The change failure rate measures the number of deployments that resulted in application failures or errors compared to the total number of deployments. A lower change failure rate indicates the quality of the change process and the effectiveness of automated testing.

Code Coverage: Code coverage measures the percentage of code in the code base that was executed through automated tests. Higher code coverage means that a greater extent of the code base has been tested, thus increasing code quality and trustworthiness.

Mean time to failure (MTTR): Mean time to failure measures the average time from the occurrence of a failure to the time it is resolved. A lower MTTR indicates the ability to resolve issues faster, minimizing downtime and impact to customers.

Lead Time (LTT): Lead time measures the average time it takes from code submission to deployment to production. Shorter LTT indicates faster development and deployment cycles, resulting in faster time-to-market for new features and fixes.

Practical case:

Consider a software company that has implemented a CI/CD pipeline for its Java application. They are tracking the following metrics:

  • Build time: 10 minutes
  • Deployment frequency: 3 times per week
  • Deployment failure rate: 5%
  • Change failure rate: 10%
  • Code coverage: 90%
  • Mean time to failure: 2 hours
  • Lead time: 3 days

By regularly monitoring and analyzing these metrics, the company Bottlenecks in processes can be identified and improved. For example, a higher change failure rate may indicate that automated testing needs improvement, while a longer LTT may indicate that the build or deployment process could be optimized.

By tracking these metrics, teams can continuously monitor their CI/CD and automated deployment processes and make informed decisions to improve efficiency, quality, and reliability.
