Nearly every federal CIO is looking at some form of virtual desktop infrastructure or VDI. It’s becoming as ubiquitous as cloud computing, mobility and big data in discussions.
VDI in many respects is one step to move toward the cloud and in other respects it’s its own approach that may or may not include cloud computing. Many agencies see VDI has better and more secure approach to mobile computing and telework.
Others see it as a way to move away from the thick client set up that has permeated most organizations over the last 20 years and back toward a thin or zero client set up for desktop computing. Several studies over the last year showed agencies see VDI as the gateway to mobility and as a way to improve cost effectiveness and efficiency in their network.
At the same time, the challenges to implementing VDI are pretty typical–business applications may not integrate easily with VDI, and, of course, security.
Some say VDI isn’t more secure than traditional desktops because it’s the end point device that causes most of the headaches for the security folks. But there are plenty of benefits from VDI, according to Gunnar Berger’s August 2012 blog post for Gartner.
He says VDI is easier to manage because thousands of desktops can run off a single central image. This also means security is improved because you have to only worry about securing that one image.
Berger also says VDI improves performance because of the time it takes to get data and how you can access data since any device is an access point. So we know there are risks and benefits, and like any technology, agencies need to figure out how best to calculate whether the benefits outweigh the risks. Part of the decision comes in how agencies can figure out their return on investment. Will it take one year, three years or longer?
Most would agree the cost to implement VDI is about equal to implementing thick clients. But it’s the longer-term savings where VDI tends to come out ahead. The question is just how much ahead. You have to understand things such as configuration planning, storage costs and licensing.
