Service Patterns
1. API Gateway Pattern
- Single entry point for all client requests
- Authentication and authorization
- Request routing and load balancing
- Rate limiting and throttling
2. Event Sourcing
- All state changes captured as events
- Complete audit trail
- Event replay capability
- CQRS implementation
3. Saga Pattern
- Distributed transaction management
- Compensating transactions
- State machine orchestration
- Failure recovery
Monitoring & Observability
Each service exports metrics, logs, and traces for comprehensive observability
- Metrics: Prometheus + Grafana
- Logging: ELK Stack (Elasticsearch, Logstash, Kibana)
- Tracing: Jaeger with OpenTelemetry
- Alerting: PagerDuty integration
Service SLAs
| Service | Availability | Latency (p99) | Error Rate |
