Scalability
• 100 virtual servers may be
mid-large deployment
• 5K desktops, images, clients,
users ~ 2x order of magnitude
IT Manager users• Deal with virtual server end-
users – more sophisticated
• Deal with end-users - less
sophisticated
System Integration • Integrates with server
management systems
• Microsoft® Active Directory™,
enterprise build process etc.
