Which Desktop Virtualization Model is Best - VDI, Type 2, Type 1?
1 comment, 1575 views
I’ve read a number of articles and blogs lately that tout one form of desktop virtualization infrastructure over another. Some say thin terminals running against desktops hosted on virtual server farms (VDI/HVD/CVD) is the most obvious solution. Why would you want the complexity of a desktop on the edge when you can centralize everything?
Others claim that the best solution is to run a desktop within a desktop – to use a “Type 2” hypervisor to host a secure corporate desktop within a less secure personal desktop. This lets me use my home computer at work (the “BYOC”, or Buy Your Own Computer model) even though my personal computer is untrusted.
Yet others say that the best solution is a “Type 1” hypervisor (also called a bare metal hypervisor), giving you the benefits of managing only one desktop operating system and gaining the benefits of a common and manageable infrastructure.
IMHO, they are all correct. There are valid use cases for each of these models, and they really depend on a wide range of factors that are specific to each and every enterprise. For example, how long has it been since your last desktop hardware refresh? If it has been awhile, then likely your PCs/notebooks aren't going to be able to run a Type 2 very well (too much CPU and memory required). Maybe then a Type 1 or VDI is best? Does your company have a green culture? Then maybe you want to go with VDI and thin terminals to reduce your energy footprint. But what about your road warriors? Maybe best is the corporate desktop on a USB stick (using a Type 2 hypervisor), or more likely run a Type 1 on a laptop to reduce the footprint but keep all the manageability.
The real problem to me isn’t which type of hypervisor infrastructure to use. It is instead how to manage the operating system and applications across your entire virtual infrastructure, while retaining all of your employees personalization and productivity. I should be able to have my personal desktop available no matter what desktop virtualization model IT implements. Maybe I need to travel and would like to take my desktop on a USB stick? Or maybe I need to log into a thin terminal at one of my companies “hotel cubes” for a few hours. Maybe I want to work from home inside a secure desktop that runs on top of my personal (unsecured) machine. Or maybe I just want my notebook to be a fully functional, fully personal desktop even when traveling at 35,000 feet and disconnected from the network.
I want it all. And why not? With Unidesk, I will be able to have it all. A desktop that is free from the confines of the physical box, free from the infrastructure that contains it. Let me work when I need to work, and in the most cost effective/green/portable/secure/connected/personal way that meets my individual consumer and business productivity needs.

They all forgetting the end user !!! Virtualization as security solution and not osersized crossconnected thinclients with master degree demands to manage and admin and not to mention license pays ! If zou are enterprise oriented then say so laud and clear ! But for end user is not of interest to have oversized virtualization tech to virtualize whole os in os and that multiple times ! its costs and is hardware demanding solution absolutely no go for end user ! I personaly use iCore Virtual Accounts and i have found not similar tech solution even comercial one to operate in similar way ! That is virtual security solution if you like so is disposable easy to manage bu have some downtimes also ! That is solution that MS is missed in Windows OS ! Not App Virtualization not Hyper-V and so on ... ! Just simple isolated virtual environment secure userspace environmet in which you can use os in ordinary way like before ! And what is more important no aditionaly cost for license pay ! One OS and on top secure isolated environments type 2 hpervisor with level os virtualization environment ! Why is important to have such security implemented in os ! MS is most unrelaiblae OS on the planet but most widely spreaded and used ! Why ? Its esy to use and is comercial making interesant for software debvelopers ! If native installed os crashes then godbye data settings and sometimes completely data loss due to all threads that exists in MS Windows ! And MS thinks tha his OS is most secure and stable not to mention BSOD and so on ... ! So if something go wrong in virtual environment then you can easy clean viruses malware and so on, but if crashes then only in virtual environment preserving native OS and no real downtime ! That is virtual security that is desired for end user ! Sandboxie, BufferZone and some other are to be used but that is only tiny solution and not good enough ! So you my think for end user solution to for all win and not hardware dependable like XEN and some others !!!
