What are the Licensed component for deploying Windows 7 or 8 as VM in Citrix VDI implementation ?

Hi Folks,

I'm planning to deploy 350 Windows 7 OS Virtual Machine for my Citrix XenDesktop 7.1 VDI projects, this VM will be accessed by the users internally in the office by using Laptop and PC which already got OEM sticker of Windows 7 workstation.

What sort of licensing that I need ?

Suppose I pay for VDA $100 per VM deployed (active) yearly, does it also cover the scenario where the VDI Win7 VM is accessible by the user from Tablet or home PC published by Citrix StoreFront ?

I can't speak to the Citrix side of things, but with VDA you are licensing Windows desktops in the virtual environment. It doesn't matter how you access them. The virtual desktops are the virtual desktops and you are licensing Windows in that environment not the connection method.

So irrespective of what the software agreement or license I got with Microsoft, I will still need to get VDA license per Client OS I have ?
jhyieslaCommented:
My understanding is that VDA licenses the Windows OS on the virtual desktop. If you have 100 licenses and 100 machines spun up, you can only have 100 desktops in use. So, no, it shouldn't make any difference about who or where or how, just that the virtual desktops running and being used are licensed.

Here's a nice link that may explain things.

Cool, so that's all it is right from the Client OS side ?

What about the license types ? which on is more economical ? Software Assurance or other agreement ?
jhyieslaCommented:
Yes, your client side should not be an issue in this regard.

The SA is more expensive up front, but it does give you rights to move onto another version of Windows without having to buy the whole license again. If you have an EA, you may be able to work some better pricing. Your licensing vendor should be able to guide you the right direction for this particular piece in light of the rest of your environment.

ok, so in this case getting the Software Assurance licensing scheme is the best way to go for long term VDI implementation and during the agreement period I can have support as well ?
jhyieslaCommented:
It all depends on your implementation and how often you upgrade Windows, but typically, yes, SA can be a cheaper way to go and it gives you the flexibility to upgrade to any version of Windows you want without having to re-buy the whole license again. Also you may not have a choice... there are some licensing agreements that MS only does with SA, but I'm not a guru on that subject; your VAR could give you a for sure answer.

As far as I can tell, you do not get support with SA. It allows you to upgrade to newer versions of Windows and it has some added benefits in meeting MS licensing scenarios, but I've not found anything related to VDA that mentions support.
