Service Statelessness Principle

A design principle that is applied within the service-orientation design paradigm, in order to design scalable services by separating them from their state data whenever possible. This results in reduction of the resources consumed by a service, as the actual state data management is delegated to an external component or to an architectural extension. By reducing resource consumption, the service can handle more requests in a reliable manner. The correct application of service statelessness requires an understanding of the various types of state information that need to be managed, like context, business, or session data. ← Wikipedia
