Patchworking and VDI. 2


I actually started writing this post a couple weeks ago but got sidetracked with other things and it just sat here on this blog with a title. So after reading Brian’s posts on why use and not use VDI, I decided to finalize this post. So here we go.

 A word on the title of this post, Patchworking, if you have no idea what it means (take a look at the formal definition on Wikipedia), is putting together small pieces of different fabrics into a larger design. Awesome stuff. For quilts and bed sheets.

Not for IT.

I remember another thread at Brian’s website where I posted a comment exactly about this issue that IMHO plagues VDI as of today. In order to get it working properly you need to rely on pieces (solutions) from several different vendors and that is where the problem begins. You may end up with a solution that runs Citrix XenDesktop that requires Windows Server 2003/2008 for its components, all these running on top of VMWare vSphere running on top of HP Blades connected to a Brocade SAN, all that tied into ILIO, vScaler and vDeDupe from Atlantis Computing. Sounds great and reliable, doesn’t it?

I see this type of solution as a house of cards. As soon as the first one falls, you are in for a great ride. Downhill. Spiraling. Imagine calling Microsoft to report an issue you are having with your virtualized Windows 7 that is using a virtual profile solution from RTOSoft (you can buy me a beer later Kevin) and that the actual VM image is based on a master clone and deltas handled by another product from vendor VDI-MILFs. I am almost certain Microsoft will hang up on your face. Right there at the spot.

Not to put you down on your VDI thoughts; in a way this is what happened in the TS/Citrix world 10 years ago. Remember the experience of calling vendor A and telling them you had their masterpieshit installed on Citrix? They would tell you nice things along the lines of ‘go screw yourself ok?’.

The point is, it took TS/Citrix almost a DECADE for God’s sake to become something we can consider ‘stable’. Note I am not using the words ‘rock solid’. TS and Citrix were not and probably will never be 100% reliable (or 95% for that matter). Remember people, we are talking Microsoft and Citrix here. Using Microsoft, Citrix and rock solid stability on the same phrase creates a paradox. Always keep that in mind.

So why would this be different with VDI? Brian thinks (I hope by now, he realizes his prophecy about VDI will fail) 2010 is the year VDI will take off and become the #1 priority for all IT departments. TS/Citrix took 10+ damn years to get to what it is today. Why VDI will be able to become an easy to deploy, cheap and stable solution in 2 years is beyond my comprehension. Call me dumb, stupid or anything else similar but I fail to see this happening now.

Will it get there? Sure it will. In 2010? No. More like 2020. 🙂

And as Jeroen nailed with his comment on the ‘Why use VDI’ thread, deploying the whole thing is complex to start with, even when using a single vendor (i.e. Citrix all the way or Microsoft all the way). After you start you realize several components are not there so you need to start sewing together all these pieces from other vendors. Now you got your patchwork.

I am not saying there is no place for VDI and that you guys all are nuts. No. I am just saying, like I have been doing with the whole UIA (User Installed Apps)/BYOPS (yes, I coined the term Bring Your Own Piece of Shit), that there are several hurdles and issues not only to get VDI going but to support it and many people in the industry, inebriated by the chance of putting their hands/making a career on a new, exciting technology, are simply not mentioning and/or ignoring them.

Not the case at this end. I see both sides of the coin. One is pretty and shiny. The other one…

So before you try to convince your boss to spend ten times more on a VDI solution (when compared to a real desktop one or to a 10+ year old mature solution like TS) just because you do need iTunes to run in a hosted environment and figured out it does not work on TS, hold on your horses. There is more to VDI than most vendors are willing to tell you.

You will thank me later.
