Abstract:
In the last years, the need for integrating QoS to service oriented architecture (SOA) has become a significant factor for managing service-based systems. In addition, combining self-* and policy-based management has major advantages since it reduces complexity management and effectively drives self-adaptation of Web services. Current service oriented architecture does not support policy-based self-management. In this paper, we present a SOA model based on autonomic registries which are endowed with self-* capabilities. Autonomic registries are in charge of managing their content and collaborating in a federated manner with other autonomic actors in order to maintain service quality, and consequently to participate in the self-adaptation process of executing Web services. The proposed model is combined with a technology that has found popularity and acceptance namely WS-Policy. We extend WS-Policy to represent a rich Web service information model based on QoS data and additional information such as service specific adaptation actions. UDDI is also extended to support policy-based self-management.
