Visual Studio Magazine has a nice article that gives a good intro and 360-degree view of MS’s “cloud” data services offerings. These are now available for use via the VS 2008 / .NET 3.5 SP1 release.
There are a lot of individual, but related offerings coming from MS under the “… Data Services” umbrella. In general, they are MS’s cloud computing and REST based technologies. These technologies are common for public services on the web since they are simple to use and based on widely accepted standards. I’m not yet clear on how these will be used inside the enterprise.
I’d love to hear what others think about this stuff!
