​
Deployment Strategy

  • Platform: Kubernetes 1.28
  • Container Runtime: containerd
  • Service Mesh: Istio
  • Registry: AWS ECR
pipeline:
  - lint: ESLint, golangci-lint
  - test: Unit & integration tests
  - build: Multi-stage Docker builds
  - scan: Security vulnerability scanning
  - deploy: Blue-green deployment
  • Development: Feature branches auto-deploy
  • Staging: Mirrors production configuration
  • Production: Multi-region deployment
  • DR Site: Hot standby in secondary region

​
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
