Last month I mentioned briefly that the Connected Systems Division was working on some interesting "cloud" services, starting with Relay and STS services. The picture is now starting to unveil, and now they have been publicly announced as "BizTalk Services", with a new home at http://labs.biztalk.net/!
The Relay Service is now the "BizTalk Connectivity Services", and the STS is now the "BIzTalk Identity Services", with two more services (ServiceBus and Workflow Services) coming soon! This is a very interesting set of services that I think are well worth taking a look at and playing with.
To get started, read first John Shewchuck post on the "Why" of BizTalk Services and then head over to Dennis Pilarinos post on how to get started with them.
