In the DevOps method, CI and CD, i.e., continuous integration and continuous delivery, are of extreme importance. Many people use these terms interchangeably, which is incorrect since these concepts are entirely unlike each other. Continuous integration appears first in DevOps. It is used to merge code changes with the existent program as frequently as possible. The newly formed version is then verified and put through automation testing before another fresh build. Continuous delivery comes next. It is used to deploy this newly merged code to a particular environment. This happens just after validating and integrating the code changes and is essentially an addition to the continuous integration phase.
