The VDI Party is Over
When looking through some of the documents I have collected over the last years, I found an interesting statement made by Yankee Group. Their prediction was that VDI will get mainstream in 2009. Well, this prediction is a couple of years old and we all know that it didn’t happen. I don’t want to put Yankee Group on the spot; three years ago there were many other market analysts saying exactly the same. But what happened to the VDI hype? Attending Citrix Synergy in San Francisco and BriForum in London this month allowed me dig a little deeper into this.
For many years Citrix was the undisputed market leader in virtual desktop solutions. But about a year ago they started investing seriously into technologies that allow them to move away from VDI. The latest version of their strategy included things like the cloud management platform CloudStack, the unified storefront Cloud Gateway and project Avalon for delivering Windows apps and desktops as a cloud service. In essence, Citrix is moving towards aggregating and orchestrating. VDI is still an important building block, but obviously not the core foundation of future Citrix product offerings anymore. Citrix officially declared the post-PC era, just like VMware did. When I understand Mark Templeton’s keynote right, Citrix are concentrating on getting established as a major player in the cloud market. It looks like they want to be the ones who provide the platform and the infrastructure for delivering cloud services in a massively scalable way. Fair enough, but in such a world VDI is only a niche.
All this became even more obvious at BriForum. Brian Madden, Jack Madden and Gabe Knuth just released their new book called the VDI Delusion. Wait a second; is this the same Brian Madden who said only a couple of years ago that VDI will be ruling the world? In all fairness, when Brian made this statement he referred to VDI versus Terminal Services. Today it is clear that neither of these two technologies is the magic silver bullet. In fact, we are facing a growing diversity in application deployment methods – locally installed apps, streamed apps and desktops, remote apps and desktops, hypervisors on clients and servers, layering technologies and many more. Not to forget the also growing diversity of devices. It turns out that virtual desktops are not the ideal solution when using mobile devices without mouse, without keyboard and with small screens.
But even if the form factor of the endpoint is suitable for full Windows desktops, many users and some IT professionals are confronted with a “surprising” fact – VDI relies on graphics and multimedia remoting technologies. I personally don’t know what some people thought how graphical desktop and application elements were supposed to be delivered to the endpoint when using VDI, but I suspect they were hoping for some kind of magic after reading market analysis reports a couple of years ago. Now, after trying things out, they find out that even IT cannot beat the laws of nature, such as the speed of light resulting in network latencies. It turned out that the promised Champaign was only water. Bummer!
I still believe that remoting technologies have a great future, in particular after seeing very promising results of a number of RemoteFX tests I’ve done with the beta builds of Windows 8 and Windwos Server 2012. Not to forget Citrix HDX, Teradici/VMware PCoIP, Quest EOP or Ericom Blaze. But it’s remote Windows apps that people want to use when needed, but not full Windows desktops. The full desktop is not so important anymore, it’s the context-oriented delivery of apps that really matters – and most of them are running on Windows. Nope, the PC era is not over yet, but the VDI party definitely is.
