CI/CD pipelines are automated systems that enable software development teams to build, test, and deploy code changes with minimal manual intervention. CI/CD stands for Continuous Integration and Continuous Deployment (or Continuous Delivery). These pipelines are fundamental to modern software development practices, allowing teams to release updates more frequently and reliably.

Continuous Integration

Continuous Integration involves automatically testing and integrating code changes into a shared repository multiple times per day. When a developer commits code, the pipeline triggers automated builds and test suites to verify that the new code does not break existing functionality. This approach catches integration problems early and maintains code quality throughout the development process.

Continuous Deployment and Delivery

Continuous Delivery automates the release process so that tested code can be deployed to production at any time, though deployment may still require manual approval. Continuous Deployment takes this further by automatically deploying every validated change to production without human intervention. The choice between these approaches depends on organizational risk tolerance and business requirements.

Common Tools and Implementation

CI/CD pipelines are implemented using specialized platforms such as Jenkins, GitLab CI/CD, GitHub Actions, and CircleCI. These tools orchestrate workflows that include code compilation, automated testing, security scanning, and deployment steps. Configuration is typically managed through code files stored alongside the application, enabling teams to version control and review pipeline changes as part of the development process.
