gRPC in .NET

RPC vs gRPC

RPC: A technique to construct distributed client-server-based applications. It is like you make a local call, but it invokes something at that distributed machine and sends you a response
gRPC: A modern open source high performance Remote Procedure Call (RPC) framework, g stands for Google.

gRPC vs REST

Let’s see some differences b/w these two protocols.

Protocol: gRPC uses HTTP/2, and REST uses HTTP/1.1
Data Format: gRPC uses protocol buffers, and REST uses JSON/XML
Streaming: gRPC is bi-directional while REST works on request/response model
Performance: gRPC performance is better than REST

Benefits of gRPC

It is faster because it uses protocol buffers
It supports multiple languages making it a tool of choice for polyglot languages (Polyglot: using multiple programming languages to serve different tasks)
It supports four types of communication (Unary, server streaming, client streaming, and bi-directional streaming.

When to use gRPC in .Net?

Microservices Architecture: gRPC, with its small, fast, and efficient binary size, is ideal for microservices.
Real-Time Applications: It’s a perfect fit for real-time and streaming applications due to its support for bidirectional streaming.
Polyglot Environments: If your application needs to communicate with services written in multiple languages.
