"Service-Oriented Business Integration: Will we be Dynamic?"

Abstract

In the modern economy, tight collaboration between business organizations is becoming increasingly important to deal with complex customer requirements, complex technology, and diverse, global markets. This collaboration requires fine-grained integration of business functions, business processes and their supporting information systems. However, quickly changing market circumstances demand high levels of flexibility in collaboration. Agile business networks are based on on-the-fly partner reselection, dynamic service level adaptation, or run-time process modification. Service-orientation is commonly seen as the approach of choice to reach this flexible business integration. Research into automated support for dynamic, service-oriented business networks goes back for more than a decade - so one may expect quite some experience and impact here. This presentation discusses what 'dynamism' in networks entails in its traditional and more extreme forms. It illustrates what we have (and haven't) developed to support dynamic business networks and how this has been picked up by business practice. In doing so, the presentation tries to give an outlook into the nearby future: 'will we be dynamic'?

Paul Grefen is a full professor in the Department of Industrial Engineering & Innovation Sciences at Eindhoven University of Technology since 2003. He chairs the Information Systems subdepartment since 2006. He received his Ph.D. in 1992 from the University of Twente. From 1992 until early 2003, he held assistant and associate professor positions in the Computer Science Department at the University of Twente. He was a visiting researcher at Stanford University in 1994. He was involved in the WIDE ESPRIT project, which focused on advanced database support for workflow management systems, the CrossFlow IST project, which aimed at cross-organizational workflow support for dynamic virtual enterprises, the CrossWork IST project focusing on advanced process support in the automotive industry, as well as various research projects within the Netherlands. He is a member of the editorial boards of the International Journal of Cooperative Information Systems and the International Journal of Service Oriented Computing and Applications. He has been a member of the program committees of a large number of international conferences and a regular reviewer for several international journals. He is the main editor of the book on the WIDE project, co-editor of the book on the CrossWork project, and has published books on workflow management and on e-business. He is a member of the Executive Board of the European Supply Chain Forum. His current research interests include architectural design of complex information systems, interorganizational business process management, high-level transaction management and contract support in electronic business.

"How to Fail with Web Services"

Abstract
Enterprise computing has finally woken up to the value of Web services. This technology has become a basic foundation of Service Oriented Architecture (SOA), which despite recent controversy is still very much the architectural approach favored by sectors as diverse as corporate IT, healthcare, and the military. But despite strong vision, excellent technology, and very good intensions, commercial success with SOA remains rare. Successful SOA starts with success in an actual implementation; for most organizations, this means a small proof-of-concept or a modest suite of Web services applications. This is an important first step, but it is here where most groups stumble. When SOA initiatives fail on their first real implementation, it disillusions participants, erodes the confidence of stakeholders, and even the best-designed architecture will be perceived as just another failed IT initiative. For over six years, Layer 7 has been building real web Services-based architectures for government clients and some of the world's largest corporations. In this time, we have seen repeated patterns of bad practice, pitfalls, misinterpretations, and gaps in technology. This talk is about what happens when web Services moves out of the lab and into general use. By understanding this, we are better able to meet tomorrow's challenges, when Web services move into the cloud.

K. Scott Morrison is the Chief Technology Officer and Chief Architect at Layer 7 Technologies, where he is leading a team developing the next generation of security infrastructure for cloud computing and SOA. An architect and developer of highly scalable, enterprise systems for over 20 years, Scott has extensive experience across industry sectors as diverse as health, travel and transportation, and financial services. He has been a Director of Architecture and Technology at Infowave Software, a leading maker of wireless security and acceleration software for mobile devices, and was a senior architect at IBM. Before shifting to the private sector, Scott was with the world-renowned medical research program of the University of British Columbia, studying neurodegenerative disorders using medical imaging technology.

Scott is a dynamic, entertaining and highly sought-after speaker. He has published over 50 book chapters, magazine articles, and papers in medical, physics, and engineering journals. He is the co-author of the graduate-level text Cloud Computing, Principles, Systems and Applications published by Springer, as well as Java Web Services Unleashed and Professional JMS. Scott is an editor of the WS-I Basic Security Profile, and is co-author of the original WS-Federation specification. He is a recent co-author of the Cloud Security Alliance's Security Guidance for Critical Areas of Focus in Cloud Computing, and an author of that organization's Top Threats to Cloud Computing research. Scott was recently a featured speaker for the Privacy Commission of Canada's public consultation into the privacy implications of cloud computing. Scott has lent his expertise to the film and television industry, consulting on a number of features including the X-Files. Scott's current interests are in cloud computing, Web services security, enterprise architecture and secure mobile computing-and of course, his two great kids.
