CI/CD Patterns & Best Practices Guide Everything you need to know to build reliable, maintainable CI/CD pipelines.

Fail fast Put the cheapest, fastest checks first. A linting error that takes 2 seconds to detect shouldn't wait behind a 10-minute integration test suite. Lint (10s) → Unit Tests (1m) → Build (2m) → Integration Tests (5m) → Deploy 2. Keep pipelines idempotent Running the same pipeline twice on the same commit should produce the same result. No side effects, no partial states. 3. Make deployments boring If your deployment process gives you anxiety, it's too complex. Automate until deploying feels like pushing a button (because it should be pushing a button). 4. Parallelize where possible ┌── Lint ──┐ push → ├── Test ──├── B
