Network Abstractions: Remote Procedure Calls

RPCs abstract network communication, letting developers call functions on a remote server as if they were local method calls. This abstraction hides details such as argument serialization, network transmission, and retry logic.

What is an RPC?

Remote Procedure Call (RPC) is a widely used interprocess communication protocol in distributed systems. In the OSI model, it spans the transport and application layers. RPCs enable a program to execute a subroutine in a separate address space, typically on a different machine.

Note: Programmers write the code as a standard local procedure call, ignoring the underlying details of remote interaction.
