Microsoft cuts costs of virtual servers

Microsoft's new virtualization licensing model for its Windows Server System could dramatically lower costs for users and help advance industry efforts to define how software
should be licensed as virtualization takes off on corporate networks.
Last week, Microsoft added licensing terms for its server operating systems that support virtual machine technology. The company
also added various use-rights, including a pay-only-for-what-you-use model, for the other software it develops under the Windows
Server System banner, including SQL Server, Exchange, SharePoint Portal Server and BizTalk.
While some users were pleasantly surprised by the licensing changes, analysts say in the long term Microsoft has only taken
its first step into the evolving virtualization-licensing arena.
"This is better than I was expecting," says Lance Auman, director of enterprise infrastructure for the San Francisco Unified
School District. Auman uses Microsoft's Virtual Server to consolidate infrastructure. "Up until now we have been treating
virtual machines like regular hardware in terms of licensing," he says. "When you put these changes into [Microsoft's] educational
pricing, cost is almost nothing. It is so negligible it is almost free."
With the virtualization licensing, which takes effect Dec. 1, users can run four virtual machines on top of the Enterprise
Edition of Windows Server 2003 Release 2, which is slated to ship in December, without any additional licensing costs beyond
the base server. Users can run any Windows server version within those virtual machines, including Windows 2000 and NT.
Microsoft says given current retail pricing a user would pay $4,000 for a Windows Server 2003 Release 2 license plus $1,000
each for four copies of Windows Server Release 2 Standard Edition to run within virtual machine technology, for a total of
$8,000. Under the new licensing the same configuration would be half that price.
The company also changed its licensing for virtual copies, or images of Windows Server System software, such as SQL Server
and Exchange, and will now charge only for virtual images that are active. Previously, Microsoft charged for every image of
a system whether it was actively used or on standby for tasks such as failover.
Microsoft also announced a number of partners that will support its Virtual Hard Disk technology, a format designed to help
third parties create management tools for Virtual Server.
Analysts say there could be other benefits beyond cost.
"This is going to give organizations a lot of ways to think through disaster-recovery and business-continuity plans," says
Chris Burry, technology infrastructure practice director for consulting firm Avanade. "In the past, those decisions may have
been cost prohibitive." He says the benefits could extend to blade server deployments.
"You might keep some virtual servers on some storage fabric and shift them in and out of blades as you need them because you
only license what you are running," he says.
