gRPC Architecture & Communication Patterns

Communication Models

1. Unary RPC - Simple request-response (like HTTP REST)
2. Server Streaming - One request, multiple responses
3. Client Streaming - Multiple requests, one response
4. Bidirectional Streaming - Both sides send multiple messages independently

Architecture Patterns

• Microservices - Service-to-service communication
• API Gateway - HTTP/REST to gRPC transcoding
• Load Balancing - Client-side and server-side strategies
• Service Discovery - Consul, etcd, Kubernetes DNS integration
• Resilience - Circuit breakers, retries, fault tolerance
