Design Microservices Architecture with Patterns and Principles - How gRPC Works

The video tutorial explains RPC as a client-server communication method using function calls instead of HTTP. GRPC allows a client application to call a server method on a different machine as if it were local, simplifying the creation of distributed applications. GRPC services define methods that can be called remotely, with servers implementing interfaces and clients using stubs. GRPC supports various environments and languages, enabling cross-language communication through protocol files.
