A Release Pipeline is a set of processes that automate the deployment of applications to different environments. It involves stages such as building, testing, and deploying code changes in a controlled and automated manner. Release pipelines ensure that software moves from development to production smoothly, consistently, and reliably. They often integrate with version control systems, CI/CD tools, and testing frameworks to automate the entire software delivery lifecycle. Tools like Jenkins, Azure DevOps, GitLab CI/CD, and CircleCI are commonly used to create and manage release pipelines. By automating deployments, release pipelines help reduce manual errors, speed up release cycles, and ensure high-quality software delivery.
