ABSTRACT
Event-based systems and the publish/subscribe style are widely used to notify subscribers when certain events of interest occur. In the context of Service-oriented Architecture (SOA) and Web services, event notifications can be used to address one issue inherent to the SOA paradigm: Services and Quality of Service attributes are changing regularly but service consumers cannot react automatically. In current service registry standards, notifications are mainly used to inform about changes in the registry data, which does not include service runtime information. In this paper, we present a SOA runtime environment that leverages event processing for Web services to support the full service lifecycle, including runtime information concerning service discovery and invocation, as well as Quality of Service attributes.
