Jenkins is a self-contained, open-source automation server that provides a continuous integration and continuous delivery (CI/CD) pipeline. It's written in Java and runs on various platforms, including Windows, Linux, and macOS. Jenkins allows developers to automate the non-creative parts of the software development process, freeing them up to focus on writing code.

Jenkins is used in various stages of the software development lifecycle. Here are some of its key use cases:

Continuous Integration (CI)

Jenkins is primarily used for CI, which involves automatically building and testing code changes as soon as they're committed to the repository. This helps catch issues early in the development process.

Continuous Delivery (CD)

Jenkins also supports CD, which involves automatically deploying code changes to production-like environments. This ensures that the code that's being tested is the same as the code that's being deployed.

Infrastructure as Code (IaC)

Jenkins can be used to automate the provisioning and management of infrastructure. This is known as IaC, and it involves using tools like Terraform or CloudFormation to define and manage infrastructure in a declarative way.
