How does Continuous Integration/Continuous Delivery work?

[mstakh.i.mom.i]

In today's software development, it is important to quickly and securely integrate and deploy changes to code bases into productive systems. A CI/CD pipeline (Continuous Integration/Continuous Delivery) is a process for automating the build, test and deployment of applications. The idea behind CI/CD is to quickly and securely integrate and deploy changes to code bases into productive systems.


Continuous integration/continuous delivery consists of various steps that are usually canadian hospitals email list controlled by a tool (e.g. Jenkins, GitLab CI). The first step is continuous integration (CI), where changes to the code are integrated into a central repository. As soon as a change is made to the code, a build process is automatically started that compiles the code and checks it for errors.

Once the build has completed successfully, automated tests are run to ensure that the code is error-free and meets all requirements. Once all tests have completed successfully, the code is deployed to a test environment where further testing can be performed.

Once these tests have been completed successfully, the code is finally deployed to the production environment, making the changes visible to end users.
