A CI/CD pipeline automates software or infrastructure-as-code delivery from source code to production. It consists of build, test, delivery, and deployment stages. Continuous Integration (CI) covers the build and test stages, while Continuous Delivery / Deployment (CD) refers to the automatic release to a repository after the CI stage and the automatic deployment of the artifact that has been delivered. A good pipeline should be reliable, accurate, and fast. Key benefits of using CI/CD pipelines include reduced costs, reduced time to deployment, enabling continuous feedback, improving team collaboration, and audit trails.
