CI/CD in Jenkins refers to the practice of Continuous Integration and Continuous Delivery or Deployment using Jenkins, which is a popular open-source automation server used for building, testing, and deploying software applications.

Continuous Integration (CI) is the practice of frequently merging code changes from multiple developers into a shared code repository and testing the changes automatically. Jenkins provides a wide range of plugins and integrations with various tools, enabling developers to automate the build and test processes of their software projects.

Continuous Delivery (CD) is the practice of automatically deploying the tested and validated code changes into the production environment, providing a faster feedback loop and reducing the time to market. Jenkins provides a range of plugins for continuous delivery, including tools for infrastructure as code, containerization, and deployment automation.

By combining CI and CD practices in Jenkins, software development teams can accelerate the development process, improve the quality of their software, and reduce the risks associated with manual deployments.

What is difference between delivery and deployment?

Delivery and deployment are related terms in software development, but they refer to different stages in the release process.

Delivery refers to the process of delivering a software application or service to a target environment, such as a staging or production environment, where it can be tested or used by end users. Delivery typically involves packaging and transferring the code, configuration, and other artifacts required to run the application, but it does not necessarily involve the actual deployment of the code.

Deployment, on the other hand, refers to the process of actually deploying the code and other artifacts to the target environment, where it can be run and used by end-users. Deployment involves setting up the infrastructure, configuring the application, and making sure that it runs correctly in the target environment. Deployment is typically the final step in the release process, and it follows delivery.

In summary, delivery is the act of delivering the software to a target environment, while deployment is the act of actually installing and configuring the software in that environment.
