Jenkins and CI/CD

Jenkins and CI/CD represent a core practice and toolset within DevOps for automating the software delivery lifecycle. Continuous Integration (CI) is the practice of frequently merging developer code changes into a central repository, followed by automated builds and tests, while Continuous Delivery/Deployment (CD) extends this by automatically releasing validated changes to a testing or production environment. Jenkins, a leading open-source automation server, orchestrates these workflows, known as pipelines, allowing teams to build, test, and deploy software more frequently and reliably, thereby accelerating development cycles and improving software quality.
