RPC (Remote Procedure Call)

A technology platform used to enable components on different physical servers to communicate with each other. RPC technology relies on the use of a proxy that represents a remote component by providing a local copy of that component's technical interface for the component initiating the invocation of the remote component.

From an SOA perspective, RPC-based application designs tend to focus on the exchange of granular parameter data. This type of interaction is often known as RPC-centric data exchange and is in contrast to the coarser-grained data exchange that is sometimes considered more preferable for services. Coarse-grained data granularity is often referred to as document-centric message exchanges because it is typically implemented using Web services (or another messaging-based platform) to exchange larger portions of data at once. Often these bodies of data represent entire business documents, such as invoices and customer records.
