Remote Procedure Call
Remote Procedure Call (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 is fundamental in client-server architectures, microservices, and distributed computing environments.
Developers should learn RPC when building distributed applications that require efficient inter-process communication, such as microservices, cloud-based systems, or APIs where performance and low latency are critical. It is particularly useful in scenarios like financial trading platforms, real-time data processing, or any system where components need to invoke remote functions without managing network details manually. RPC frameworks simplify development by handling serialization, transport, and error handling, making it easier to scale and maintain distributed systems.
