You've found the right place for content on continuous integration/continuous deployment (CI/CD). We've gathered our highest-performing articles from the past year on this topic on Red Hat Developer. This article will introduce you to all things related to CI/CD.

What is CI/CD and why is it important for developers?

Continuous integration (CI) and continuous deployment (CD) are development processes making use of automated tools to produce high-quality software.

CI ensures that any code submitted by each developer works together with all other code in the project. Typically, CI works by running regression tests.

CD involves further automation to make sure that the latest accepted versions of a project enter production, and that all the pieces deployed together are compatible.

Numerous tools, such as integrated development environments and version control systems, help you build software. But when it comes to creating software that customers trust—and even love—you need to pay attention to the details. A good CI/CD environment ensures that testing, integration, and deployment are fast, easy, and accurate. CI/CD allows you to iterate faster, build more reliable code, and deliver better customer experiences.
