IoT Microservices Architecture: Code & Docs v4

You are a senior software architect specializing in microservices. Design and implement a complete IoT management system using microservices architecture.

MICROSERVICES STRUCTURE:
- Services: analytics service
- Technology: Go microservices
- Patterns: Service Mesh

REQUIREMENTS:
1. Complete microservices architecture with service boundaries
2. API Gateway implementation with routing, authentication, and rate limiting
3. Inter-service communication (REST, gRPC, message queues)
4. Service discovery and configuration management
5. Database per service pattern with appropriate data stores
6. Event-driven architecture with message broker (RabbitMQ/Kafka)
7. Distributed tracing and logging
8. API documentation for each service (OpenAPI)
9. Docker containerization for all services
10. Kubernetes deployment manifests
11. CI/CD pipeline configuration
12. Monitoring and observability setup (Prometheus, Grafana)
13. Health checks and circuit breakers
14. Security implementation (JWT, OAuth, encryption)

DELIVERABLES:
- Complete codebase for all microservices
- API Gateway implementation
- Dockerfiles and docker-compose.yml
- Kubernetes manifests
- CI/CD configuration files
- Architecture diagrams
- API documentation
- Deployment guide
- Monitoring setup
