Client virtualization is a hot topic these days.
Many IT organizations are taking a look at
client virtualization and considering a proof
of concept or pilot project as an option to
move away from the typical rich client. With
that comes a lot of questions regarding
which direction to go in: Do you go with a
true thin, or do you stay with a rich client?
What options do you have with the rich
client? I am going to address some of the
options that we have today, taking you down
the path of pros and cons for both, and then
taking a look at typical usage models.

  2. 2. Client Virtualization: What Are My Options? By Richard Nockels, Intel Client Marketing Manager © 2010 Dell/Intel Richard Nockels is Intel Client Marketing Manager. In his ten years at Intel, Richard has focused primarily on marketing efforts around the BIOS business PC segment. These efforts include the creation of marketing messages for Intel’s vPro technology and streamed computing strategies, supporting end customer sales engagements, and training Intel’s field sales teams on the wide variety of Intel products supporting the business PC marketplace. This IT Briefing is based on a Dell/Intel/TechTarget Webcast, “Client Virtualization: The What Are My Options?” This TechTarget IT Briefing covers the following topics: • Spectrum of Compute Models . . . . . . . . . . . . . . . . . . . . . . . . . . .1 • What Makes Sense to Centralize? . . . . . . . . . . . . . . . . . . . . . . . .1 • Dynamic Virtual Client Advantage . . . . . . . . . . . . . . . . . . . . . . . 3 • Application Virtualization . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4 • OS Streaming . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4 • Virtual Containers . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .5 • Virtual Container Usage Examples . . . . . . . . . . . . . . . . . . . . . . . 6 • Common Questions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8 Copyright © 2010 Dell/VMware.
