Microsoft has a multitiered program for virtualization licensing. It can seem a bit confusing at first, but it ensures you get just what you need.
Adapted from “Microsoft Windows 7 Administrator’s Reference” (Syngress, an imprint of Elsevier)
Windows 7 can support many different methods of virtualization and use them in combinations to meet your organization’s deployment needs. Using Windows 7 in combination with Windows Server 2008 and Hyper-V and the Microsoft System Center Suite provides your enterprise with a flexible and robust environment, and gives your users the desktop they require. This starts with the desktop itself and extends to access to applications or a completely hosted desktop.
The key to all of this is a new licensing model that Microsoft has developed to go along with its virtualization offerings. The Virtual Enterprise Centralized Desktop (VECD) license is the Windows 7 license that lets you virtualize Windows desktops.
The VECD license is the Windows 7 license that permits and manages virtualization. Traditionally, a user would be licensed to access only one desktop at a time on a single, specific device. When a new desktop device was installed, it typically required a new Windows license. If it relocated an existing license, the previous desktop was taken out of service.
With virtualization, this is not the typical use case anymore. The VECD lets you run a copy of Windows 7 in a datacenter that might provision multiple desktops across several servers in production and for disaster recovery.
A VECD license allows the following:
The key to the VECD license is that your desktops must be covered under Microsoft Software Assurance (SA). This is a requirement to even purchase the VECD license. This can ultimately save a great deal on the cost of the upgrade and support of the Windows 7 environment.
Imagine your company has 100 laptops and desktops, and also 100 thin clients. If the laptops didn’t have SA, you would need 200 VECD licenses (for the 100 thin clients and 100 laptops). If the laptops did have SA, you would need 100 VECD licenses (just for the 100 laptops).
You would need to maintain SA on each of the laptops. It would be a good idea to learn more about Microsoft volume licensing policies as they pertain to virtualization or contact your Microsoft licensing specialist.
As you can see from this simple example, you could save a significant amount on your licensing costs if you decide to leverage virtualization in your business. Although it can seem a bit tricky at first look, it’s worth spending a few minutes discussing the benefits and requirements with your Microsoft licensing provider.
