Abstract :
Web service failures or degradations directly cause operational inefficiencies and financial losses in Web service-based business processes (WSBP). In today\´s competitive Web service market a considerable number of functionally-similar Web services offered by different providers are differentiated by competitive QoS levels and pricing structures. Consequently, dynamic and optimal Web service selection is a significant challenge to business organizations which run such WSBPs. Having a cost-effective and efficient Web service selection approach is becoming an important necessity for such organizations. Current Web service selection approaches offer "one-size-fits-all"; solution, i.e., one optimal service selection for all running BP instances. However, such solutions are neither efficient nor cost-effective given that the service levels of WSBPs are associated with customers classes/profiles, e.g., Gold, Silver or Bronze. Therefore, we propose a group-based Web service selection approach, "one-size-does-not-fit-all", that optimizes multiple QoS criteria and differentiate the service selection based on the BP customers classes/profiles. Our approach shows a very good improvement over existing "one-size-fits-all" approaches; 65% average cost reduction and 30% utility value improvement.
