✍️ Daily Summary – 14.04.2025
Massive progress day.
I completed three core automation tasks (SNS alerts, ECR cleanup, RDS retention) and laid the foundation for project documentation. These were key for transitioning the project into a maintainable and explainable state.
✍️ Daily Summary – 16.04.2025
Project completed.
All documentation was finalized, infrastructure was reviewed and polished, and the last bits of automation were tested. The entire M300 project is now officially complete and decommissioned. All Terraform modules, Lambda logic, CloudWatch, RDS, ECS, and ECR components are clean, secured, and documented.

✅ Weekly Results
- 📩 SNS Notifications: Confirmed working via test alarms + email alerts.
- 🧹 ECR Lifecycle: Old and untagged images now cleaned up automatically.
- 🗑️ RDS Cleanup: Lambda now deletes old snapshots to prevent cost bloat.
- 📘 Documentation: All key components documented. Clean, complete, and usable as a reference.
- 🏁 M300 Project Completed. All infrastructure has been decommissioned and archived.
⚠️ Problems Faced
- ECR lifecycle policies took time to propagate; results weren’t instant.
- Had to delete old Lambda zip deployments manually during testing.
- Initial snapshot filter was too aggressive—refined it to target only
rayan-tagged snapshots.
❓ Open Questions
- Should lifecycle cleanup be extended to include CloudWatch logs or S3 objects?
- What's the best tool for final infrastructure diagram visuals? (draw.io, Lucidchart, etc.)
- Should I host the documentation as a static site (e.g., MkDocs or GitHub Pages)?
