“What is CI/CD?” Easy-to-understand continuous integration and continuous delivery

Continuous integration (CI) and continuous delivery (CD), or CI/CD for short, consists of the culture, operational principles, and set of operations that application development teams use to deliver more frequent and reliable code changes. do.

CI/CD is a recommendation for DevOps teams and also a recommendation for agile methodologies. CI/CD automates integration and delivery, freeing software development teams to focus on meeting business requirements while ensuring code quality and software security.

Meaning of CI/CD

Continuous integration is a coding principle and set of practices that encourages development teams to implement small code changes from time to time and check them into version control repositories. Because most modern applications require code development using a variety of platforms and tools, teams need a consistent mechanism to incorporate and validate changes. Continuous integration establishes an automated way to build, package, and test applications. Having a consistent integration process naturally leads developers to commit code changes more often, which leads to better collaboration and code quality.

Continuous delivery begins at the end of continuous integration and automates the delivery of applications to the environment of choice, including production, development, and test environments. Continuous delivery is an automated way to push code changes into these environments.

CI/CD pipeline automation

The CI/CD tool helps store environment-specific parameters that need to be packaged at each delivery stage. CI/CD automation makes the necessary service calls to web servers, databases and other services that need to be restarted. You can also run other procedures after deployment.

CI/CD also requires continuous testing, as the goal is to provide quality code and applications. In continuous testing, an automated series of regression, performance, and other tests are run in a CI/CD pipeline.
