The debate about REST (REpresentational State Transfer) as an alternative to SOAP has been going on for several years now - with more and more respect for the REST point of view in the recent past. While many will agree that a RESTful approach is a better match for Web 2.0-style, public-facing Internet services, it's still often questioned how REST could be applied to 'Enterprise' scenarios. This talk will briefly summarize the REST principles behind the Web's architecture, and then show how an enterprise scenario can benefit from the properties that have made the Web a success.
