Answer:- Make sure to go through this question as it is one of the important interview questions. Implementing CI and CD pipelines ensures quality and reliable code. Azure pipelines are there to ensure a secure, easy, and quick way to automate processes for project development as well as their availability. They are completely free for use in public projects and cost-effective for private ones (free 30 hours per month). Below are a few reasons for using CI/CD and Azure pipelines: • Supports any platform or language • Enables work with open-source project> • Building on Windows, Mac, and Linux machines • Enables simultaneous deployment to various types of a target • Integration with GitHub and Azure deployments
