RPCbased

RPC-based refers to software architectures that rely on remote procedure calls, allowing a client to invoke a procedure on a remote server as if it were a local function. The call is packaged with the procedure name and arguments, transmitted over a network, executed by the server, and the result is returned to the client. This abstraction hides many details of network communication, data serialization, and error handling behind a simple API, enabling straightforward integration of distributed components.

In RPC-based systems, service interfaces are defined in a contract, and code stubs or generated clients handle marshalling, transport, and deserialization. Common RPC models include traditional synchronous RPC and modern frameworks such as gRPC, JSON-RPC, XML-RPC, and Apache Thrift. RPC frameworks typically provide language bindings, multiple transport options, and features like deadlines, streaming, and authentication, which help coordinate calls across service boundaries.

Advantages of RPC-based design include a straightforward programming model, strong interface contracts, language interoperability, and robust tooling for multi-language ecosystems. Drawbacks include sensitivity to network latency and partial failure modes, the need for careful versioning and compatibility management, serialization overhead, and security considerations such as authentication and encryption. RPC-based systems can introduce tighter coupling to specific frameworks or protocols, which may affect evolution and interoperability.

RPC-based architectures are commonly used in microservices and distributed systems where services require efficient, well-defined method calls across process or machine boundaries. They contrast with request/response styles like REST by emphasizing direct remote invocation of procedures rather than resource-oriented interactions.
