Fundamental of Backend Communications and Protocol

Design Patterns

Request - Response

Client sends a request, then server parses and then processes the request, finally send a response to the client, which parses it and consumes.

Where it is used?

• Web, HTTP, DNS. SSH
• RPC (Remote Procedure Call)
