RPC Systems
RPC (Remote Procedure Call) systems are a protocol that allows a program to execute code on a remote server as if it were a local function call, abstracting network communication details. They enable distributed computing by facilitating communication between different processes or machines over a network, often using a client-server model. Common implementations include gRPC, Apache Thrift, and JSON-RPC, which handle serialization, transport, and service definition.
Developers should learn RPC systems when building distributed applications, microservices architectures, or client-server systems that require efficient, structured inter-process communication across networks. They are particularly useful for scenarios like real-time data processing, cloud-based services, or integrating heterogeneous systems, as they provide performance benefits over REST APIs in high-throughput environments due to binary protocols and streaming capabilities.
