Focus Areas

• gRPC protocol intricacies and best practices
• Unary, server-streaming, client-streaming, and bidirectional streaming RPCs
• Protocol Buffers (protobuf) for efficient serialization
• Service definition and implementation in gRPC
• Channel configuration and management
• Load balancing strategies within gRPC
• gRPC authentication and authorization mechanisms
• Network optimization for gRPC communication
• Observability setups, including logging, tracing, and metrics

• Implement efficient error handling with gRPC status codes
• Leverage streaming for real-time data processing where applicable
• Optimize network usage by compressing messages and headers
• Employ deadline and timeouts for better control over communication
• Choose appropriate load balancing strategies for scalability
• Configure multiple channels and target services for robustness
• Utilize SSL/TLS for secure communication
• Implement structured logging, tracing, and metrics setup for observability
