Introduction to Jenkins:
Brief History and Evolution
Jenkins, originally known as Hudson, was created by Kohsuke Kawaguchi in 2004 as an open-source automation server. Its primary purpose was to automate the building, testing, and deployment of software projects. Over the years, Jenkins has evolved into a versatile and widely adopted tool within the software development community.
Purpose and Importance in the Software Development Lifecycle
Jenkins plays a pivotal role in the Software Development Lifecycle (SDLC) by facilitating Continuous Integration (CI) and Continuous Delivery (CD). CI involves automatically integrating code changes from multiple contributors, ensuring that new code additions do not break the existing codebase. CD extends this concept to automatically deliver code changes to production, streamlining the release process and enhancing the software development workflow.
