Dynamic Composite Web Service Execution by Providing Fault-Tolerance and QoS Monitoring

Résumé

One of the major goals of the Service Oriented Architecture is to support automatic Web Service (WS) composition and execution, allowing a user query to be satisfied by a Composite WS (CWS). User queries express functional and non-functional (QoS) requirements. QoS requirements indicate, for example, the maximum execution time or price allowed for a CWS execution. In this work, we propose a model to support CWS executions while maintaining the QoS requirements, even in presence of failures. QoS monitoring is performed during the entire execution of a CWS in order to satisfy QoS requirements, influencing the choice of the fault-tolerance strategy selection in case of failures.
