What is the purpose of release pipelines when the same tasks are available in build pipeline

Question

I am using azure build and release pipelines. I understand that build pipeline produces an artifact that can be used by release pipelines and deployment can be organized into stages with options to deploy/re-deploy stage.

However, I also notice that all tasks available in release pipeline are also available in the build pipeline. Also the documentation for build pipeline states that it can be used to build, test and deploy. So what exactly is the benefit of using release pipelines?

Answer 1

Release pipelines in Azure Pipelines assist your team in consistently delivering software to your clients at a quicker and less risky pace. You may fully automate software testing and delivery in numerous phases all the way to production.
