Web services management and selection: applied performance mechanisms

Abstract

Research to date on composite Web services (CWS) has focused on selection of servers and precedence between requests as opposed to the requirements of the clients. This paper proposes that CWSs should have greater emphasis on both the individual customer requirements and the resultant impact on the performance of the overall system. The system described here employs the use of Web service level agreements and hard-and-soft criteria to develop an efficient Web service manager.
