Distributed event processing for fault management of Web Services

Within service orientation (SO) web services (WS) are the defacto standard for implementing service-oriented systems. While consumers of WS want to get uninterrupted and reliable service from the service providers WS providers can not always provide services in the expected level due to faults and failures in the system. As a result the fault management of these systems is becoming crucial. This work presents a distributed event-driven architecture for fault management of Web Services. According to the architecture managed WS report different events to the event databases. From event databases these events are sent to event processors. The event processors are distributed over the network. They process the events, detect fault scenarios in the event stream and manage faults in the WS.
