Introduction Guide to RPC in Golang

RPC (Remote Procedure Call) simplifies communication between services by allowing a procedure to be executed on a remote machine as if it was a local function. This guide explains the need for RPC in place of traditional API calls in distributed systems, provides an example of a key-value store implementation, and outlines server and client design in Golang using the rpc package. It also covers the structure of RPC functions and the practical steps to run both the server and client.
