Two contradictory stories
It all started about 2 weeks ago when Citrix and VMware shared the status of VDI business. There were two contradictory stories – Citrix announced some large purchases and implementations for Citrix XenDesktop and VMware announced that larger projects are being pushed out to 2010.
VDI is doomed for failure
Then came some reports on how VDI projects have recently failed. I like calling these not so successful VDI projects as ‘first generation’ architectures that are destined for failure. As the author notes that these projects start ‘innocently’ – with the goal of putting a desktop on top of the existing server virtualization platofrm. In other words ‘We have done server virtualization – we can now do the same for the desktop’. Unfortunately, that is where the problem starts. Recently, Brian Madden published a story highlighting the problem. Two weeks ago, I heard customers sharing their frustrations and concerns about why desktop virtualization is different from server virtualization.
I spoke with our CTO, Harry Labana, and Harry walked me through the top 5 reasons why in his experience VDI projects will fail if they are done with a presumption that desktop virtualization is similar to server virtualization.
The fact is that implementing Desktop virtualization or VDI is mre like implementing any other server based computing technology, such as Terminal Services. The VDI infrastructure that may be resident in the data center; however, it goes beyond the data center to the network, the end points and the user. So, unless the implementations are planned with network, device and end users in mind they are destined to fail. Good design, on the other hand, will lead to successful implementations. But that means doing the right due-diligence of products up front – including network, end points and end users. Or else you will fall into the similar trap as others are falling into.
