It's quite common when thinking about virtualization technology to
focus on the server side. But moving forward, it's the client side that
will take on a greater role in deploying new operating systems, maintaining
those systems, and ensuring their stable and secure use.
A popular virtualized client environment includes a Virtual Desktop Infrastructure
(VDI) running on a thin client or zero client, with a connection back to a
data center of virtualized clients. Although the VDI approach is a solid one,
it's worth considering alternatives. Why? Because mobile users, for
instance, need an OS that travels with them and isn't completely dependent
on a steady Internet connection to ensure remote desktop functionality.
New desktop and notebook computers now include built-in Type-1 hypervisor
support, making it easier to power virtualization from within the devices
themselves. The problem, however, with native hypervisor support is that a
native hypervisor needs to be able to "talk" to various graphic
cards, network and storage adapters, and so forth. The server world certainly
has a lot less to worry about in terms of diversity than the client world
does, making a native client hypervisor a bit tricky.
Nevertheless, solutions are finally arriving. There are three essential aspects
to planning ahead for the bare-metal, client-side virtualization world that's
First: You have to identify a manufacturer that is designing
both the hypervisor and the backend management solution for the client systems
that will help you create, update, deploy and manage your enterprise VMs easily.
An example is Citrix System's XenClient. Built using XenServer technology,
XenClient allows for multiple desktop systems to run as VMs on the hypervisor.
Second: You have to consider the hardware that may be necessary
to ensure a smooth rollout. Not all systems perform equally well. For example,
with the XenClient solution, systems running the Intel vPro technology are
ideal because that's what XenClient is built upon. Imagine the cleanest
system possible considering both the hardware and software that will be used.

Third: Ensure that the cost of the virtualization solution
you choose is justified for your environment. Needs and wants are two separate
things in this recession-battered world, so you have to look at total cost
of ownership and return on investment.
In considering where the benefits lie for a large-scale deployment of bare-metal
systems (both desktop and notebook systems), there is a greater level of control
achieved when you have a management solution that can provide the following:
The bare-metal client is going to become the norm in modern IT. It's
time to start investigating your options. Pick a platform you can trust, with
a solid reputation for support and product excellence, and go bare.
