Cloud-Native Patterns

Twelve-Factor App

1. Codebase: One codebase, many deploys
2. Dependencies: Explicitly declare and isolate
3. Config: Store in environment
4. Backing Services: Treat as attached resources
5. Build, Release, Run: Strictly separate stages
6. Processes: Execute as stateless processes
7. Port Binding: Export services via port
8. Concurrency: Scale out via process model
9. Disposability: Fast startup and graceful shutdown
10. Dev/Prod Parity: Keep environments similar
11. Logs: Treat as event streams
12. Admin Processes: Run as one-off processes
