Service Composition and Coordination
(KM-SC)


. Service Wiring is a composition type in which a set of interacting services is assembled into a deployment package. Such package, called service assembly, can be deployed in a run-time environment, ready to be invoked as a service itself. Services specify provided and requested interfaces in form of operations with inputs and outputs. In order to create executable service assemblies, the requested interfaces of one service are wired to provided interfaces of other services. The services assembled in this way can again be recursively exposed as a service which can be wired and invoked. A service assembly is a deployable artifact, which is deployed to an Enterprise Service Bus (ESB). Service Component Architecture (SCA) is a service wiring technology.

Service Infrastructure
(KM-SI)

Service Component Architecture (SCA) is a service wiring technology.

In several SCA platform as Tuscany [Tuscany] or Frascati [FraSCAti], Service-Based System can be adapted through a modification of the SCA wire. These modification are performed using depency injection mechanism.

Service Component Architecture (SCA) is a service wiring technology.

SCA Policy specification provides a framework to support specification of constraints, capabilities and QoS expectations from component design through to concrete deployment. The capture and expression of non-functional requirements is an important aspect of service definition and has an impact on SCA throughout the lifecycle of components and compositions. This specification describes the SCA policy association framework that allows policies and policy subjects specified using WS-Policy [WS-Policy] and WS-PolicyAttachment [WS-PolicyAttachment] , as well as with other policy languages, to be associated with SCA components.[SCAPolicyFramework]
