If you look on the VMware site it will tell you that VDI reduces the total cost of desktop ownership by 50 percent. VMware provides a fairly comprehensive list of cost savings that will enable and justify this TCO investment, including:
- Reducing acquisition costs for PC hardware
- Reducing CapEx costs by extending the useful life of PC hardware
- Reducing OpEx costs with better desktop management and automation
- Reducing costs and risks in Windows 7 migration
- Minimizing potential lost revenue from PC downtime.
If you’re not sure about the impact of VDI in your own environment, you can use a TCO Calculator provided by VMware to figure our your own savings. Cisco and other companies provide similar offers and solutions to measure TCO in VDI deployments.
Microsoft, as you would expect, is a little less aggressive in promoting potential TCO reductions. On the Desktop Virtualization page on its Web site it mentions TCO reduction as one of the benefits of Microsoft Desktop Virtualization, but when it talks specifically about VDI it focuses much less on TCO than on these areas:
- Integrated management
- Enhanced security and compliance
- Anywhere access from connected devices
- Increased business continuity
You’d expect differences in the marketing and positioning of the two companies that will inevitably fight it out for domination in the desktop virtualization software market. VMware has everything to gain by promoting a dramatic paradigm shift in desktop computing: Microsoft has everything (well, not quite everything) to lose in such a scenario.
In a survey by InformationWeek last summer, IT pros said they were looking to VDI as an enabler to cut operating expenses, save staff time and reduce service calls. But when it came to TCO there were still questions about the impact.
TCO, like beauty, is in the eye of the beholder. Search the Web and you will find glowing case studies of companies saving millions of dollars using VDI. You will also find quotes and examples of companies expressing concern about the upfront investment involved in VDI and the complexities in managing a new desktop environment.
With VDI TCO metrics, a lot depends on how you measure some of the harder-to-measure benefits such as reduced downtime or improved productivity or faster recovery from disasters. A lot also depends on how far you are willing to go in your VDI deployment – how many users, how many desktops, how many applications – and what types of devices you are going to be using. Clearly there are potential savings in client devices with less-rich desktops, but how are you measuring those savings versus the increased spending in storage, servers and networks? And how are you measuring TCO based on the users that you have selected for deployment? The impact will differ dramatically among different types of users.
