• Continuous integration. Jenkins can run automatic builds every time a change is made to the code repository. This helps catch errors early and keep the code in a stable state. It supports multiple version control systems such as Git, SVN, and Mercurial.
• Build distribution. Jenkins can distribute build and test tasks across multiple nodes, which speeds up processing. Builds run on remote machines configured as agents, enabling scalability.
• Pipeline as Code. Lets you define complex workflows using scripts in Groovy format. Pipelines can include stages such as compilation, unit testing, code analysis, and deployment to specific environments.
• Extensible plugins. Jenkins has a wide library of plugins that extend its functionality. These plugins enable integration with tools such as Docker, Kubernetes, SonarQube, and Slack.
• Monitoring and notifications. Provides detailed reports on build status and sends alerts in case of failures. Supports notifications via email, instant messaging, and dashboards.
• Test automation. Jenkins can run automated test suites after every code change. It supports frameworks such as JUnit, TestNG, and Selenium for unit and UI testing.
• Continuous deployment. Facilitates automatic deployment of applications to staging or production environments. Integrates with tools such as Ansible, Chef, and Puppet to manage configurations.
• Environment management. Lets you define and manage multiple development, testing, and production environments. Each environment can have its own configurations and access policies.
• Logging and auditing. Keeps a complete history of all executions, including detailed logs and performance metrics. This makes it easier to identify problems and comply with regulations.
• Cloud integration. Supports deployments on cloud platforms such as AWS, Azure, and Google Cloud. Allows dynamic creation of cloud nodes to handle variable workloads.

Jenkins was created in 2011 by Kohsuke Kawaguchi as a fork of the Hudson project. Originally developed in Java, it emerged due to differences between the community and Oracle over the governance of the Hudson project. Since then, Jenkins has grown thanks to contributions from a broad community of developers. Its modular architecture and focus on automation have made it a standard tool in DevOps.
