Service oriented computing provides technologies that enable integration of services provided by multiple organizations over the Internet. Typical execution behavior in this type of distributed systems involves a set of autonomous peers interacting with each other through messages. A conversation is the global sequence of messages exchanged among the peers participating to a composite Web service. A choreography specification identifies the set of allowable conversations for a composite Web service. An orchestration, on the other hand, is an executable specification that identifies the steps of execution for the peers. This conversation based modeling framework leads to interesting problems such as realizability, synthesis, conformance, and synchronizability. I will talk about our work on these topics. I will also talk about the Computer Science research at the University of California, Santa Barbara for the students who are interested in applying to our graduate programs.
