An Autonomic Computing Architecture for Self-* Web Services

Adaptation in Web services has gained a significant attention and becomes a key feature of Web services. Indeed, in a dynamic environment such as the Web, it's imperative to design an effective system which can continuously adapt itself to the changes (service failure, changing of QoS offering, etc.). However, current Web service standards and technologies don’t provide a suitable architecture in which all aspects of self-adaptability can be designed. Moreover, Web Services lack ability to adapt to the changing environment without human intervention. In this paper, we propose an autonomic computing approach for Web services’ self-adaptation. More precisely, Web services are considered as autonomic systems, that is, systems that have self-* properties. An agent-based approach is also proposed to deal with the achievement of Web services self-adaptation.
