What is CI/CD?
Continuous Integration and Continuous Deployment — automated practices for building, testing, and deploying code changes.
CI (Continuous Integration) automatically builds and tests code whenever developers push changes, catching bugs early. CD (Continuous Deployment/Delivery) automates releasing tested code to production or staging environments.
Popular CI/CD tools include GitHub Actions, GitLab CI, Jenkins, CircleCI, and Travis CI. A typical pipeline includes stages: build, test, security scan, deploy to staging, and deploy to production.
