Desktop virtualization has continued to make headlines in IT, but despite the focus on the topic, there are a number of myths that remain. The root cause is that there are actually many flavors of desktop virtualization and what’s true for one type is not always true for another.
It is costly and requires major investment in infrastructure.
This is only true of server-hosted desktop virtualization, which centralizes both the management and the execution of virtual desktops. Desktop virtualization reduces costs because it only centralizes the management while harnessing the power of PCs for the execution of virtual desktops on a secure local hypervisor.
It is complicated and can take several months to set up.
With server-hosted desktop virtualization, the workload is being moved from the desktop to the data center. This movement of the workload creates complexity — requiring network hardware, WAN-accelerators and other technologies to try to compensate. With desktop virtualization, the execution of the virtual desktops is local, so no complex infrastructure is required to set it up.
It does not work for laptops or users that are often disconnected from the server.
Because the client hypervisor is installed directly onto the laptop without any operating system between the hypervisor and the hardware, the laptop is fully managed through the centralized management system. So organizations have a single solution that works equally regardless of whether they are using desktop PCs or laptops.
Business continuoity with desktop virtualization is costly and complex.
With desktop virtualization, if a single computer goes down only one user is impacted and if the servers or network go down everyone can just keep working. Desktop virtualization also includes transparent automated backup capabilities, so in the event that a PC is lost, broken or stolen, users can get their desktop back the way it was on a brand new machine in about 15 minutes.
