Citrix seemed to have been a partner to Amazon: http://aws.amazon.com/solutions/global-solution-providers/ci...

Not sure if Workspaces has any sort of collaboration with Citrix.

It wouldn't be. This is powered by Teradici's PCoIP solution (I worked on that) which is the competition to the Citrix HDX protocol. Teradici used to partner primarily with VMware and compete with Citrix in VDI.
