Jenkins is primarily used for continuous integration and continuous delivery (CI/CD) in software development. It automates various stages of the software development lifecycle, including building, testing, and deployment processes. Developers rely on Jenkins to automatically compile and test code changes, integrate code from multiple contributors, and streamline the deployment of software to different environments. With its extensive plugin ecosystem, Jenkins can integrate with a wide range of tools and services, making it a versatile and essential tool for teams aiming to improve development efficiency, code quality, and software delivery reliability.

Jenkins is a versatile tool that serves as both a Continuous Integration (CI) and Continuous Delivery (CD) platform. In its CI role, Jenkins automates the integration of code changes from multiple developers into a shared repository, automating build processes and running tests to ensure code quality. In its CD role, Jenkins automates the deployment of code to different environments, enabling teams to define and automate the entire delivery pipeline, from development to production. Its flexibility allows organizations to use it for CI, CD, or both, making it a comprehensive solution for streamlining the software development lifecycle and ensuring the reliable and efficient delivery of software applications.
