|
||
|
|
### Infrastructure as Code

- Clear interfaces between systems
|
||
|
|
|
||
|
|

|
||
|
|
- Production-quality error handling and logging
|
||
|
|
- Security hardening and compliance considerations
|
||
|
|
|
||
|
|
### Observability First
|
||
|
|
- Comprehensive logging and monitoring
|
||
|
|
- Automated alerting and incident response
|
||
|
|
- Performance metrics and health checks
|
||
|
|
|
||
|
|
## Technology Stack
|
||

|
||
|
|
- **Visualization:** Grafana
|
||
|
|
- **CI/CD:** Gitea Actions

|
||
|
|
|
||
|
|
