Desktop virtualization is coming to enterprise, as many companies are beginning to serve their employees' applications and data from a cloud, rather than having said applications and data on employees' computers. Virtualization providers Citrix Systems (NASDAQ:CTXS) and VMware (NYSE:VMW) maintain that desktop virtualization brings about a reduction of resource need, simplified IT administration, improved security, and increased productivity, as users can access workstations from different locations and devices.
But, while basic productivity applications work well when served up this way, graphics-intensive applications, which would normally be accelerated with a GPU such as those provided by NVIDIA (NASDAQ:NVDA), do not. Instead, they either overwhelm the server's CPU or need to be throttled back, providing a poor user experience. In other words, although it's been possible to virtualize the workstation of a project manager who uses Word and Excel, it was effectively impossible to virtualize the workstation of a designer who uses Photoshop or an engineer who uses AutoCAD.
NVIDIA to the rescue
The first step toward improving this situation came in 2012 with the introduction of GPU pass-through technology, which allowed a dedicated GPU to be assigned to a virtual desktop. This provides good performance for the user, but it is often impractically expensive, as each virtual desktop requires its own GPU, whether the user is making full use of this or not.
The real breakthrough came with the introduction of NVIDIA's Grid product in early 2013. Basically, NVIDIA Grid uses NVIDIA's Kepler architecture and provides an environment in which the GPU can be used in a virtualized setting and shared by multiple users. The immediate use case for this was cloud-based gaming, but it wasn't long before Grid was applied to desktop virtualization as well.
Who provides what?
Even though the desktop virtualization opportunity has been heating up, one company, Citrix Systems, has made application and desktop virtualization its core business for quite a while now. It's, therefore, not surprising that Citrix was the first to provide full support for NVIDIA's graphics virtualization. Since the 7.1 release of its XenDesktop product in October 2013, Citrix supports both GPU pass-through and multi-user GPU virtualization.
Citrix's main competitor in desktop virtualization is VMware, a much larger company, and one with deep pockets thanks to its lucrative server-side virtualization business. VMware is playing catch-up to Citrix in desktop virtualization, but CEO Patrick Gelsinger recently stated, "We are the aggressor and we are winning share."
Currently, VMware's Horizon View supports GPU pass-through, as well as a slower version of multi-user graphics virtualization called virtual shared graphics acceleration (take a look at the video below for a comparison between current graphics performance with Citrix and VMware). But, VMware is catching up. In March, it announced full support for NVIDIA's virtual GPU, and will probably make this available to customers by the first half of 2015.
The giants on the side
Two other big players have stirred up the virtual desktop market in the last year. Last November, Amazon.com (NASDAQ:AMZN) launched a virtual desktop service called WorkSpaces on its Amazon Web Services platform. While WorkSpaces doesn't currently support NVIDIA's virtual GPU, AWS does, and Amazon.com has said it will add the support to WorkSpaces if customers request it.
This May, after months of rumors, Microsoft (NASDAQ:MSFT) announced Azure RemoteApp, a service that delivers Windows applications from Microsoft's Azure cloud. RemoteApp is still in beta and Azure (and therefore RemoteApp) doesn't currently offer any kind of GPU. But, with Microsoft's "mobile first, cloud first" strategy, Azure will certainly be developed further, and GPU support might not be far off.
What this means for investors
Desktop virtualization is clearly an exploding market. Patrick Moorhead at Forbes estimates that workstations will increase from the current 100 million to a staggering 600 million workstations that can be virtualized, thanks to NVIDIA's Grid technology.
Who will benefit from this? Citrix, VMware, and others will continue to fight for share of this market, requiring costly investments and probably causing a decrease in prices down the line. The opportunity is definitely there, but so is the competition.
The inevitable conclusion is that the real winner will be NVIDIA. Once desktop virtualization becomes mainstream, competition in the virtual GPU space will also increase. For the foreseeable future, however, NVIDIA is the only provider of virtual GPU technology, and it's set to benefit the most from the predicted six-fold increase in the desktop virtualization market.
