CI/CD is a set of best practices of DevOps that ensures to deliver code changes very frequently in a reliable way. Let's discuss CI/CD and CD.

  • Continuous Integration (CI) - Continuous Integration is a process where developers work on code changes and commit the code very frequently to repository. CI triggers the build every time whenever new code changes detected in repository. Unit testing is performed against these code changes every time. CI enables to detect the errors at early stage or when code is being integrated. CI is a set of principles that helps developers to manage code integrations and detect early stage bugs and rectify them.
  • Continuous Delivery (CD) - Continuous Delivery is a process where integrated code is pushed to specific environments. It ensures code delivery to specified infrastructure environment. It starts after continuous integration. CD ensures the automation of delivering new code with minimum efforts. Some extra checks are also performed during CD process such as performance test for production environment.
  • Continuous Deployment (CD) - Continuous deployment is most critical stage in pipeline. In this process code changes are automatically deployed to production environment where end customers or users are using the application. It is achieved by taking the benefit of continuous delivery by automating new stage (Production) in the pipeline. There is very less human interaction at this stage and it helps to reduce delay in making code changes live.
