Summary
CI/CD combines Continuous Integration and Continuous Delivery (or Deployment) into a unified pipeline that automates the path from code commit to production release.
What is CI/CD?
CI/CD is a set of practices and tools that automate the software delivery lifecycle. The CI part ensures that every code change is built and tested automatically, catching integration errors early. The CD part extends this by automatically deploying validated changes to staging or production environments.
A typical CI/CD pipeline includes steps such as source code checkout, dependency installation, compilation, unit and integration testing, artifact creation, and deployment. Tools like Jenkins, GitHub Actions, or GitLab CI orchestrate these steps in a repeatable, auditable way.
CI/CD is a foundational practice of DevOps culture, reducing the time between writing code and delivering value to end users while maintaining software quality through automated checks.
Why is CI/CD relevant?
- Faster delivery: Automated pipelines reduce manual effort and compress release cycles from weeks to hours
- Improved quality: Automated tests catch defects before they reach production
- Reduced risk: Smaller, more frequent releases are easier to test, roll back, and debug
