Desktop virtualisation isn't a panacea that will slay infections and slash costs - it's a problem-filled journey that may not even solve the problems you started out wanting to fix. That's one lesson attendees at IDC's Desktop Virtualisation Conference 2010 in London learnt. The easy desktop virtualisation pitch is that you …
VDI = expensive and bloated 'evolved' thin client?
If only Digital hadn't imploded :(
Yep, desktop hardware is so ridiculously cheap that you end up putting 80s supercomputers on the receptionist's desk and now somebody comes up with a 'solution' that offloads this onto expensive mainframes - sorry 'application servers'.
So what is the choice...
Next year when I have to buy the receptionist a new PC as part of the refresh and the minmum spec will be quad core, 1TB hard drive and 4GB ram, to run what, email and facebook and I will get 0.002 cpu utilisation, well that makes a hell of a lot of sense moving forward!!
VDI is not the magic bullet but it sure as hell will help as part of a mixed environment and that includes Server based computing, app virtualisation and thin clients........
Can't wait until all the task based users want hex core, maybe two years away, VDI is coming as all the alternatives are even more scary?
So how is this any different to what Citrix have been doing for a decade?
All....because we didn't pick a good muli-user OS
ALL of this crap...VDI, Citrix, VMWare is because we didn't pick a good multi-user OS.
VMWare because we picked a Server OS(Windows) that can't do more than one thing at a time apparently.
Citrix/VDI, because we picked a Desktop OS(Windows) that can't handle having more then one user live and work on it.
With UNIX/Linux I don't need VMWare to drive up my 'utilization'. I can easily and safely run a Webserver, Database Server, Web Server, and 20 different applicatons all on the same single running install of the OS.
Ditto for desktops...With Linux/Unix I can simple and easily have as many users running their desktop sessions on the systems that the processors and memory will support. No need for TRICKS or funny stuff or problems with 'trying to write to the registry' at the same place etc.
FACE IT... the whole reason we got into this mess is because we listened to clueless PEE CEE user/admins who could not see past the mouse in the their hand when it came to designing architecture.
