Hey there... man,
In a nut shell, Cloud Files is the Rackspace equivalent to AmazonS3 online storage webservice or "file hosting service", except Cloud Files also includes CDN (content distribution services) via limelight. Cloud Servers is the Rackspace Xen offering, and Cloud Sites is the web and DB hosting services. All wrapped up with the Rackspace Cloud control panel and back end auth-API. Here's some sales-less info on them: http://en.wikipedia.org/wiki/Rackspace_Cloud Scanning over it though I see that wikipedia article is a bit out of date. Our Cloud Servers offering DOES actually support Windows VMs now (in beta). Though I'm more a Linux guys myself..
Part of the coolness is that between the Cloud Servers and Cloud Files systems, we have a publicnet and servicenet interface. The latter allows direct "intra-cloud" transfers, while public (external) clients can hit the same content via CDN (limelight), allowing you to distribute your content and load via embedded URL around the world without hitting any one data center.
