Abstract
The development of composite services leads to various challenges concerning their Quality of Service (QoS) and similar non functional characteristics. On the one hand, a composite Web Service depends on the QoS properties of its own Web Service suppliers in order to provide the user with a satisfactory service. On the other hand, the main issues for the fulfillment of QoS and service-level agreements are concerned with Web Service performance variability. Indeed, the QoS of a Web Service may evolve relatively frequently, either because of internal changes or because of workload fluctuations. The performance of the composite Web Service may be significantly improved by monitoring the execution of the component Web Services and by flexibly reacting to faults and anomalies in a timely fashion.
