Remote Procedure Calls
Remote Procedure Calls (RPC) is a protocol that allows a program to execute code on a remote server or another address space as if it were a local procedure call. It abstracts the complexities of network communication, enabling distributed systems to interact seamlessly by invoking functions across different processes or machines. RPC frameworks handle serialization, transport, and error handling to make remote calls appear local to developers.
Developers should learn RPC when building distributed systems, microservices architectures, or client-server applications that require efficient inter-process communication. It is particularly useful for scenarios like cloud-based services, where components run on separate servers and need to coordinate tasks, such as in financial transactions, real-time data processing, or IoT device management. Using RPC simplifies development by hiding network details, improving performance through optimized protocols, and enabling language-agnostic communication in heterogeneous environments.
