RPC

gRPC

gRPC is a modern open source high performance RPC framework that can run in any environment.

• Efficiently connect services in and across data centers with pluggable support for load balancing, tracing, health checking, and authentication.
• Applicable in last mile of distributed computing to connect devices, mobile apps, and browsers to backend services.

Companies that use it:

• Boston Dynamics
• Neuralink

Got to work on this in my Neuralink take-home challenge!

Is this like ZeroMQ?

Is this like ROS?

gRPC seems to be built like something that scales for microservices. ROS doesn’t really do that.

gRPC is built on the idea of services.

// The greeting service definition.
service Greeter {
  // Sends a greeting
  rpc SayHello (HelloRequest) returns (HelloReply) {}
}
 
// The request message containing the user's name.
message HelloRequest {
  string name = 1;
}
 
// The response message containing the greetings
message HelloReply {
  string message = 1;
}
