   • Can be generated from docker-compose.yml

3. Monitoring Integration

   • Prometheus operator needs to be installed
   • Grafana dashboards need to be imported
   • AlertManager needs configuration

4. Multi-Region

   • Current setup is single-region
   • Multi-region DR requires additional work

7.2 Future Enhancements
