CI/CD Patterns
Best practices for building reliable, secure, and fast CI/CD pipelines with GitHub Actions.
Pipeline Stages
A well-structured pipeline follows this progression. Each stage gates the next.

Two identical environments. Switch traffic atomically.
Current traffic --> Blue (v1.0)
Green (v1.1) <-- Deploy here, test, then switch
After switch:
Current traffic --> Green (v1.1)
Blue (v1.0) <-- Rollback target
Pros
Cons
Instant rollback
Requires 2x infrastructure
Zero downtime
Database migrations need care
Full environment testing
Higher cost
Canary Deployment
Route a small percentage of traffic to the new version.
Test across multiple versions and platforms efficiently.
