## The runbooks

- [Terraform](https://christwentyfour.com/runbooks/terraform.md): Remote state from day one. Modules as components. A plan a human reads.
- [Containers & ECS](https://christwentyfour.com/runbooks/containers.md): Config comes in at startup, with no SDK calls at boot. It runs on a laptop with no cloud credentials.
- [CI/CD Pipelines](https://christwentyfour.com/runbooks/pipelines.md): The pipeline decides whether a change is safe. Keep logic in scripts, and keep it under fifteen minutes.
- [Observability](https://christwentyfour.com/runbooks/observability.md): Logs, metrics, and traces answer different questions. Structured logs are the prerequisite for letting an agent near an incident.
- [Python Automation](https://christwentyfour.com/runbooks/python.md): Most ops work is glue. Make it idempotent, observable, and safe to run twice.
