Continuous Integration & Continuous Deployment
Imagine you are working on a two weeks sprint, and your agile teams have different assignments that can only be tested through Integration Tests, which may take numerous builds in shorter periods. I still remember that a Build Engineer yelled at me for asking for three builds within an hour. With the power of CI/CD, 60% of this problem is solved with Rapid releases with just a click of the mouse or build hooks.
Problem Statement
