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.

What is the primary difference between RPC and traditional HTTP calls?

• RPC uses function calls instead of HTTP calls.

• RPC is slower than HTTP calls.

• RPC requires more bandwidth than HTTP calls.

• RPC is only used for local communication.

In GRPC, what is the role of the client application?

• To implement the server interface.

• To handle server calls.

• To directly call methods on a server application.

• To define the service methods.

What does the server side of GRPC do?

• It provides a stub for client methods.

• It defines the service methods.

• It implements the interface and runs a GRPC server.

• It calls methods on the client application.

How do GRPC clients and servers communicate across different environments?

• Using a centralized server for all communications.

• By converting all code to a single language.

• Through protocol files that define proto requests.

• By using HTTP requests.

Which of the following is true about GRPC's language support?

• GRPC supports multiple languages for both clients and servers.

• GRPC requires all applications to be written in the same language.

• GRPC only supports Java and C#.

• GRPC can only be used in server environments.
