ABSTRACT:
Service-oriented Computing (SOC) has recently received attention from both academia and industry. It introduces a new paradigm for addressing the complexity of distributed systems, by using loose coupling, platform-independent interface descriptions and well-established standards. However, current service-oriented systems are often not as dynamic and adaptable as intended. In this talk, we address some of the current challenges we see in SOC research and practice, such as service metadata and querying, as well as dynamic binding, invocation and mediation of services. We introduce the Vienna Runtime Environment for Service-oriented Computing (VRESCo) that aims at addressing these challenges to facilitate engineering of SOC applications.

The main focus of the talk is on event processing in service- oriented systems. The goal is to enable clients to subscribe in order to receive notifications if certain events of interest occur. This can range from basic events (e.g., new service is published) to more complex events and event patterns regarding service invocations and Quality of Service (QoS) attributes. We show how event processing principles have been integrated into VRESCo and give some application scenarios, such as notification- based rebinding, service provenance and QoS/SLA monitoring.
BIO:
Anton Michlmayr received his PhD degree in Computer Science from Vienna University of Technology in March 2010, while working as a university assistant at the Distributed Systems Group. His research interests include software architectures and middleware for distributed systems with an emphasis on service-oriented architectures and distributed event-based systems.
