gRPC
gRPC is a high-performance, open-source remote procedure call (RPC) framework developed by Google that uses HTTP/2 for transport and Protocol Buffers as its interface definition language. It enables efficient communication between services in distributed systems by allowing clients to call methods on a server application as if it were a local object. gRPC supports multiple programming languages and is designed for low latency and high throughput in microservices architectures.
Developers should learn and use gRPC when building microservices, cloud-native applications, or any system requiring fast, reliable inter-service communication, such as in IoT devices or real-time streaming services. It is particularly beneficial for scenarios where performance is critical, like in financial trading platforms or gaming backends, due to its efficient binary serialization and multiplexed HTTP/2 connections. gRPC also simplifies API development with strong typing and code generation from Protocol Buffer definitions.
