RPCløsninger

RPCløsninger are software architectures and tools that enable a program (the client) to execute code on a remote system (the server) by invoking procedures as if they were local functions. They rely on a defined interface, a transport mechanism, and a serialization format to transmit requests and responses across process or network boundaries.

Core concepts include an interface definition language to specify services, generated client stubs and server skeletons, and a chosen transport and serialization method. Common protocols and frameworks in this space include gRPC (HTTP/2 with Protocol Buffers), Apache Thrift, JSON-RPC, XML-RPC, SOAP, and, in older systems, CORBA. RPC support various communication patterns, including synchronous request/response, asynchronous calls, and streaming.

Benefits of RPCløsninger typically include efficient binary communication, strong typing, language-agnostic code generation, and straightforward method-based APIs that resemble local calls. Trade-offs involve tighter coupling to service contracts, versioning and schema evolution challenges, debugging complexity, and potential networking or firewall constraints. Security and reliability considerations are important, with emphasis on transport security (TLS), authentication and authorization, and operational practices such as retries, timeouts, idempotence, deadlines, load balancing, and circuit breakers.

Common use cases encompass microservices and service-oriented architectures, cross-language integrations, mobile or browser backends calling centralized services, and scenarios needing high-performance or streaming communication. When selecting an RPCløsning, teams evaluate language and platform support, performance and streaming needs, ecosystem maturity, tooling, and deployment constraints. While RPC can offer efficiency and clarity, it may require more careful versioning strategies and infrastructure planning compared with some RESTful approaches.
