Cloud terminology is already complex enough with its IaaS, SaaS, PaaS, BPaaS; so now we have one more term contributing to the overall confusion with cloud-related services. It is desktop as a service (DaaS). You might say “Well, it is just another buzz word to help marketing guys in selling virtualization” and probably you are right.
Together, IBM Global Services and Citrix have completed 15 XenDesktop rollouts in the last year that were over 1,000 seats. Several exceeded 20,000 seats with customers spread across the world. As desktop virtualization adoption expands across the enterprise, we are working together with customers to deliver virtual desktops to the entire user base of many of these organizations. IBM helps Citrix customers before and after their desktop virtualization rollout through their service offerings featuring Citrix technology.
A usual adoption pattern for cloud computing is desktops. It's really straightforward because, in general, each company has standardized desktops: only some specific version of the operating system is supported; only specific desktop flavors (styles) are available; only some applications are allowed; and typically everything is managed by the IT team.
