Software development is inherently a difficult exercise because it involves multiple processes, practices, and people. Some of the prominent reasons to adopt continuous delivery and deployment are mentioned next.
As mentioned before, continuous delivery and deployment conduct frequent deployments to multiple environments. When a developer checks in their code, an automated build pipeline is executed, and after the build pipeline completes, deployment is conducted on a test environment where functional and technical verification and validation is performed. If there is any bug, error, or issue in deploying and configuring the environment and application, immediate feedback is provided to the developer informing about the failure. The developer can find the issue and fix it, thus ensuring that the release process does not fail and, at the same time, meets the functional correctness of the solution.
