What is RPCs?

Remote Procedure Calls (RPCs) are a protocol that allows a computer program to execute a procedure in another address space (commonly on another computer on a shared network) as if it were a normal (local) procedure call. The programmer doesn't need to explicitly code for these remote interactions. RPCs are a form of client-server interaction (via request-response) and are typically used in distributed systems to enable communication and data exchange between different services or applications. Common uses include distributed computing, microservices architectures, and client-server applications.
