Server-hosted Virtual Desktops
Project Background
• Five month Burton Group project
• Goal: identify enterprise-class server-hosted
virtual desktop (SHVD) evaluation criteria
• Input sources: analysts, clients, and vendors
• Outcome
- 45 page report detailing SHVD selection criteria
- Notes that differentiate “features” from “marketing
checkboxes”
- Three 25 page product profiles (Citrix, VMware, Quest),
more on the way (Microsoft, Oracle)

Evaluation Criteria
4
Server-hosted Virtual Desktops
• Evaluation Criteria Structure
- Selecting a SHVD solution typically entails a long term
(3-5 years or more) commitment in order to realize a
true return on investment (ROI)
- Features should be assessed by grouping into three
buckets:
• Required: absolute necessities
• Preferred: important features that result in better experience,
operational management, and improved TCO
• Optional: use-case driven features needed in select
deployment scenarios
