Stefan has been involved in the design of large-scale, distributed systems for more than 15 years, using a variety of technologies and tools ranging from C/C++ and CORBA over J2EE/Java EE and Web Services to REST and Ruby on Rails. In his current work, he is actively participating in SOA projects using both RESTful HTTP as well as the WS-* universe. Stefan is the author of "REST und HTTP" and co-edited the German SOA book "SOA Expertenwissen", has written numerous articles on SOA, Web services and REST and is a frequent speaker at conferences around the world. He is a member of the SOA Manifesto Working Group, the JAX-RS (JSR 311) expert group, and headed InfoQ's SOA queue for several years.

RESTful HTTP: Using the Web for SOA Speaker: Stefan Tilkov, innoQ Day 2: REST and Service-Orientation in Practice REST is the architecture of the World Wide Web, and it has recently become noticed as a new contender for the hype of the day. In essence, RESTful HTTP means nothing more than applying the Web's technologies the way they were meant to be used, which is a strong contrast to the way Web Services based on SOAP, WSDL and the WS-* ecosystem abuse it. The benefits of using HTTP correctly include a vast variety of infrastructure components, proven interoperability, unlimited scalability and a strong architectural model governed my meaningful constraints. But while many SOA practicioners have started to accept RESTful HTTP as a viable strategy for simple use cases, there is still a wide-spread belief that more advanced cases require more complicated approaches. In this talk, we will take a look at the core ideas and principles behind REST and RESTful HTTP, address some common doubts, and show how to exploit the benefits of REST to achieve SOA goals for both basic and advanced usage scenarios. Topics covered include documentation, description and discovery, reliable communication, eventing, transactions and hypermedia. Finally, we will conclude with a list of recommendations on how to introduce a RESTful approach in step-by-step fashion into a large enterprise's overall architecture.

Rest Services vs. Web Services - A Live Debate Day 2: Expert Panel A head-on debate about the two most common service implementation mediums: SOAP-based Web Services and REST Services. Discussions will tackle issues such as suitability for service-orientation, practical applications, industry standardization, security, transactions, etc. October 6, 2010 - 17:00 Room: 001 Panelists (in alphabetical order): Toufic Boubez, Nicolai Josuttis, Mark Little, Cesare Pautasso (Moderator), Stefan Tilkov, David Chou
