• Automated testing
• Fast feedback

Continuous Deployment (CD)

Continuous Delivery Automated release to staging. Manual deployment to production.

Continuous Deployment Fully automated to production. Every change goes live.

CI/CD Pipeline Stages

1. Source

   • Code commit
   • Trigger pipeline

2. Build

   • Compile code
   • Create artifacts

3. Test

   • Unit tests
   • Integration tests
   • Security scans

4. Deploy

   • Staging environment
   • Production release

Security in CI/CD (DevSecOps)

• SAST (static analysis)
• DAST (dynamic analysis)
• Dependency scanning
• Secret detection
• Container scanning

Popular CI/CD Tools

• GitHub Actions
• GitLab CI
• Jenkins
• CircleCI
• ArgoCD

Best Practices
