A Deployment Pipeline is an important concept in Continuous Delivery. In Deployment Pipeline we break the build process into distinct stages. In each stage we get the feedback to move onto the next stage.
It is a collaborative effort between various groups involved in delivering software development.
Often the first stage in Deployment Pipeline is compiling the code and converting into binaries.
After that we run the automated tests. Depending on the scenario, there are stages like performance testing, security check, usability testing etc in a Deployment Pipeline.
In DevOps, our aim is to automate all the stages of Deployment Pipeline. With a smooth running Deployment Pipeline, we can achieve the goal of Continuous Delivery.
