gRPC

gRPC is a modern open-source high-performance Remote Procedure Call (RPC) framework that can run in any environment. It uses Protocol Buffers (Protobuf) as its Interface Definition Language (IDL).

When to Use

• Microservices Communication: Low latency, high throughput internal traffic.
• Polyglot Environments: Service A (Go) talking to Service B (Java).
• Streaming: Bidirectional streaming of data (e.g., Real-time voice/video metadata).
• Strict Contracts: When you need strict type safety across services.
