Top 5 Desktop Virtualization Models

While server virtualization has, in many ways, been a fairly straightforward and streamlined process for most organizations, the prospect of desktop virtualization is much more daunting. Server virtualization is relatively transparent to its end users, but desktop virtualization opens up a whole new can of worms that has little or nothing to do with the technology itself.

Picking the right desktop virtualization model is about more than picking the right technology to match your technology needs. It also has a lot to do with your organizational culture, your existing and planned infrastructure and your method or methods of delivery.

Accordingly, you need to take the time to make sure you’re using the model that’s right for you. Here’s a look at the five most popular desktop virtualization models being implemented today:

1.    Remotely hosted desktops. This is the traditional “terminal services” model of virtualization. Somewhere out there is a server running an OS or an application, and clients log into it using a client piece that is the only software on the client machine. Everything is transmitted across the network, including things like keyboard and mouse clicks. This kind of virtualization is low-cost, but limited in terms of the quality of the connection.

2.    Remote virtual applications. Using a web browser, you create a secure connection and transmit both data and graphics. This model doesn’t require IT to maintain control of the hardware or software of the end-user, which is in itself a double-edged sword. Also, these apps are unavailable when you’re not connected.

3.    Dedicated virtual desktops. This model hosts a virtual machine on a server that is then transmitted over to the end user. It might be streamed, or it might be fully hosted. These solutions use tremendous amount of bandwitdth, but allow you to operate in applications that won’t operate in shared mode.

4.    Localized virtual applications. Java applications are a good example of this. The application is downloaded to the client and runs there using local resources. This model uses less bandwidth and is available offline, but provides little in the way of control for IT.

5.    Localized virtual OS. This model places a hypervisor to create a VM on the client, that then functions as a standalone unit. Alternatively, that hypervisor can run on the client’s BIOS. This solution allows you multiple OSes, but it also provides all sorts of opportunity for resource conflicts.
