Desktop Virtualization

Virtual Desktop Initiative at UTC

What is desktop virtualization?A thin client device can be used instead of a full size computer. The thin client remotely connects to a server and displays the Windows 7 operating system on the thin client device connected to a monitor.

Thin Client Device

Why desktop virtualization?

• Less money (48% cheaper than PC)

• Less energy ( more than 89% more energy efficient)

• Easier to manage and maintain

• Most people are just using Microsoft Office products and surfing the web

Virtual Desktop Initiative at UTC

Cost Containment Strategy- Reducing desktop costs allow IT to redirect money to classroom technology and address greater IT needs- Better utilization of limited resources- Less staff can manage more machines- Total cost per device $632.83

(This includes device, license, and servers)

- Savings per device versus a PC $567.17

Where Deployedo Academic Computing Labs o Classroom computers in the podiumo Conference Rooms connected to large television screenso Library Computing labo Residential Living Areas

The Future

(Expansion Plans) • Areas we are looking to implement:

o Virtualize 1/3 of our public labs (500 out of 1500 public computers)o Use virtual desktops in new UTC libraryo More widely install as classroom computer in the podiumo Replace general use computers (general kiosks) with virtual machineso Replace campus operators computerso Replace Bursar's Office walk up computers and possible staff machineso Staff use throughout the university
