Introduction to gRPC

gRPC is a high-performance RPC framework that uses Protocol Buffers for serialization.

Why gRPC

• Strongly typed contracts via .proto files
• Bi-directional streaming
• Built-in authentication and load balancing
• Efficient binary encoding

Hello World

service Greeter {
  rpc SayHello (HelloRequest) returns (HelloReply);
}

message HelloRequest {
  string name = 1;
}

gRPC excels for internal microservice communication where performance matters.
