Just got back from VMworld 2009 in Cannes (France), where the present and future technology solutions on virtualization were presented.
The conference was awesome, with lots of interesting sessions, great speakers and fine location.
My main interest was oriented towards virtual client computing and application virtualization and honestly, I was a bit disappointed.
Although the idea and technology looks promising, solutions become of interest, at least from a solutions provider perspective, when they can be sold. Let’s talk in this post about Virtual Desktop Infrastructure or VDI.
In today’s economical reality, cost savings become a more crucial decision item when choosing a technology. Making a business case for VDI is not that easy when comparing to the other form of server based computing: Terminal Services. No, there is nothing wrong with your eyes…VDI is indeed just another way of server based computing. And as we all know, server based computing IS a cost saver. This brings me to the main question of each customer.
VDI, a cost saver?
I would be a happy man when I just could answer the question with a simple “yes” or “no”. But as you could guess, the answer is more than that.
TS is having the benefits here. It is proven technology, with great support through documentation and forums, …. BUT also has its limitations.
There are use cases where VDI is the better solution. Let’s think about the nerdy developer who need admin rights on his workstation or you have business application that do not have TS support. So even when you go for a server based computing environment, you could end up with 2 or more infrastructures increasing the complexity in administration. (VDI and physical pc). Same issue for with TS but at least it’s cheaper.
As we talk about server based computing, we automatically talk about the datacenter. Implementing VDI means actually you are bringing the workstation of the user into the data center to be managed centrally. Ok…that make sense…..but have you thought about the increase of storage capacity you need (which is by far larger compared to TS)? Storage on pc cost peanuts. Storage in a data center costs a great deal more.
And what about redundancy. Don’t think you can get away with just one data center. You cannot afford losing connectivity to ALL of your desktops!
These are just 3 things that I picked up.
From a solutions provider point of view, we must be able to sell a technology and services. From a customers point of view, they need a firm solution that can generate cost savings and increase productivity.
Today I cannot see a benefit for both provider as well as customer.
Can you benefit from server based computing?
The answer is yes…but not by implementing VDI.
I still prefer Terminal Service above VDI today. And let me be clear on the “today”. Things that are an obstical today are not necessarily obsticals tomorrow.
