A Stateless Service is a service whose
response does not require access or use of information nor is contained
in the input message. [CD-JRA-1.1.2] {GEN: Service} _ALT_ Service Statelessness is a design principle that is applied within the service-orientation design paradigm, in order to design scalable services by freeing up the services from managing their state data whenever possible [Cellary&Strykowski, 2009]. 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 the resource consumption, the service can handle more requests in a reliable manner.[IBM, 2008] |
