Priority Order

  1. Critical Path (Must have for demo):

    • Infrastructure (Task 1)
    • Microservices (Task 2)
    • Governance (Task 3)
    • Basic CI/CD (Task 4, partial)

  2. High Priority (Important for production-grade):

    • Complete CI/CD (Task 4)

    • Security hardening (Task 6)

  3. Medium Priority (Polish):

    • Documentation (Task 7)

Notes

  • Use terraform workspaces for different environments
  • Keep secrets in AWS Secrets Manager, never in code
  • All infrastructure should be reproducible
  • Follow 12-factor app principles
  • Test locally with LocalStack when possible
  • Use pre-commit hooks for code quality
  • Document all architectural decisions
