RPCyhteydet

RPCyhteydet refers to remote procedure call connections. This is a fundamental concept in distributed computing that allows a program on one computer to execute a procedure (subroutine or function) on another computer without the programmer explicitly coding the details of the remote interaction. The process typically involves the calling program sending a request message to the remote server, which then executes the requested procedure and sends a response message back.

The core idea behind RPC is to abstract away the complexities of network communication, making distributed programming resemble local programming. When a client makes an RPC call, it appears as if it's calling a local function. The RPC system handles the serialization of arguments, the transmission of the request over the network, the deserialization of arguments on the server, the execution of the procedure, the serialization of the return value, and the transmission of the response back to the client.

There are various RPC frameworks and protocols available, each with its own set of features and design choices. Examples include Remote Method Invocation (RMI) in Java, gRPC, and Apache Thrift. These systems often define how data is represented and transmitted, as well as mechanisms for error handling and concurrency. RPC is widely used in building microservices, web services, and other distributed applications where different components need to communicate and share functionality across a network.
