Adaptation in Web Service Composition and Execution

Overview Web services simplify enterprise application integration by facilitating reuse of existing components for creating new services. In a dynamic environment, it is imperative to design a Web Service Composition and Execution (WSCE) system that adapts to failure of component services or changes in their QoS offerings. This paper motivates a staged approach for Adaptive WSCE (A-WSCE) that cleanly separates the functional and non-functional requirements of a new service, and enables different environmental changes to be absorbed at different stages of composition and execution. They use Synthy, a prototype service creation environment, to implement their solution and demonstrate its effectiveness.
