Quality-aware Self-Management for Service Processes in Service-Oriented Architectures

One of the salient features of Service-Oriented Architectures is that services can be deployed and removed at runtime. But service replacement and management for service processes is a demanding task in complex IT-Systems, especially under additional constraints like optimizing the Quality of Service of a service process. A self-managing system is desired but missing. We have already achieved self-healing and self-optimization with our service brokering system. We apply ontologies to discover service alternatives and their QoS. In this paper we not only present our work on quality-aware service discovery but also propose a self-manageable infrastructure for service processes. The infrastructure can be dynamically instantiated, configured and bound to management endpoints with semantic service discovery. The approach not only automates the binding of service management systems of multiple vendors but also the SLA monitoring and the ad-hoc integration of services in service processes.
