RPC
RPC (Remote Procedure Call) 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, abstracting the complexities of network communication. It enables distributed computing by facilitating inter-process communication between different systems, often across a network, using a client-server model. RPC frameworks handle serialization, transport, and invocation, making it easier to build scalable and modular applications.
Developers should learn and use RPC when building distributed systems, microservices architectures, or client-server applications that require efficient and transparent communication between components running on different machines or processes. It is particularly useful in scenarios like cloud computing, where services need to interact seamlessly, or in large-scale applications where performance and reliability are critical, such as in financial systems or real-time data processing.
