Keynote speech: Research Challenges in designing Complex Autonomic Service-oriented Systems By Prof. Schahram Dustdar, Director of Vita Lab, Vienna University of Technology Today, we witness the forces of multi-dimensional globalization in the domains of business, technology, and organizational (team) forms. The interdependence of computing devices, their underlying information systems, as well as processes involving humans and software services become more complex, thus requiring business processes and software services to attain higher degrees of autonomic, context-aware, and self-adaptive behavior. In this talk I will discuss the main research challenges for this class of problems as well as present our current state in building the required novel conceptual abstractions as well as needed technological implementations and validations. Schahram Dustdar is a Full Professor of Computer Science with a focus on Internet Technologies heading the Distributed Systems Group, Institute of Information Systems, Vienna University of Technology (TU Wien) where he is director of the Vita Lab. He is Chair of the IFIP Working Group 6.4 on Internet Applications Engineering and a founding member of the Scientific Academy of Service Technology. Accepted Papers: 1.
