Search my older post and you'll find that I had already suggested VMware and other vendors to go for several versions of hypervisors. VMware has taken the stride towards mobile devices, which is definitely a good thing but that market is a flooded market.
Desktop PCs are in need for some rationalization. I have, some times, hard time convincing customers why they should move towards VDI- while many are lately wondering if Cloud Apps, hosted via their internal, on-premise Cloud Infrastructure or Off Premise Clouds - a typical hosted scenario. Either ways they just don't care anymore, so is the case of the Clouds. Clouds don't care either. That makes it a perfect match, especially the new beast we all want to comprehend, the beast which only the likes of Microsoft has understood rather well, the SMB market.
SMB's are typically the "I don't care, you fix it and fix it now" kind of folks. Taming that market segment is a real pain. They are sometimes hard to understand, they almost always want it immediately fixed and have more demands than your enterprise customers. Also, not to forget, they invest carefully and want value for every penny that is invested.
So a real tough nut to crack, when you have an Amazon like Cloud, that lets these customers do it all "self and auto", then you can really free yourself from all those enervating contacts and let them buy capacity and space themselves. Just like those airports, buy your own ticket, print it yourself, go whenever you like, check in and all we want to do is make sure that you are frisked before you embark that plane.
Similar kind of "checkpointing", will not only accelerate the pace of the commoditization in these contractionary times, but alos ensure that the "do-it-yourself-dude!" model will also save you all the trouble of understanding them. No point!
While this article goes talking about what VDI is not good at, I think it is more important to organize your "Consumer Space" with all versions: VDI, Thin Clients, Web Apps, Clustered Apps etc. That helps the "Clouds Don't Care" model.
Cheaper alternatives to desktop virtualization
For independent consultant Anil Desai, VDI presents a dilemma. It promises to address security problems such as lost laptops and give IT better control over remote workforces. But he doesn't see virtual desktop technology as the best way to solve these and other business problems.
He said there are more cost-effective ways to reduce security risks and gain control over user devices with existing technologies. There is the ability in Windows to restrict access to the USB drive or to improve manageability with remote management tools that lets IT cut physical visits to desktops and use the Remote Desktop Protocol, just as VDI uses.
Another example is the alternative of Windows Server 2008 Terminal Services for resource, hardware and management consolidation versus using VDI. Terminal Services in Windows Server 2008 lets IT run a single application in a virtual environment, in turn centralizing application management, he said.
Then there's the overall cost for a virtual desktop infrastructure versus buying desktops. "When you see how much infrastructure, power and server resources go into a VDI solution versus getting desktops that have come down so much in price, I just don't see the justification for that kind of investment," Desai said.
Desai said he is backing the concept of a client hypervisor and is waiting to see what the big three -- VMware, Microsoft and Citrix -- will do in this area. "It can reduce potential application conflicts and speed up deployments on many operating system platforms," he said.
Clouds don't care, they really shouldn't. It ain't worth the trouble!
