Microsoft Virtualization Q&A: No More Licensing Concessions, Muglia Says
As Microsoft formally launches its virtualization plans, SVP Bob Muglia sits down with CIO.com's Kevin Fogarty to talk about licensing gripes from customers and winning the battle with VMware. Microsoft's not looking to make VMs more mobile, he says.
CIO — On the eve of Microsoft's blowout virtualization launch today in Seattle, Bob Muglia, SVP of the Server and Tools Business at Microsoft talked with CIO.com writer Kevin Fogarty about OS licenses and the competitive situation with VMware, which is holding its big customer event, VMworld, next week.
Q: Some people called it a half measure when Microsoft announced in August it had changed the licensing rules to let applications shift more easily from one virtual machine to another. Have you thought about changing the OS licenses to allow the OS within a virtual machine to be shifted as well, without requiring an open OS license on both the originating and the destination machine?
Muglia: I think we've already done that, and we did it two years ago.
We realized that virtualization changed the way we needed to license our software, and we implemented a set of license changes throughout the server product line, but we started with Windows Server.
We structure our licenses so customers have the right to run a different number of instances of the operating system based on the edition they use.
With Standard Edition they can run one virtualized instance. In the case of Enterprise they're allowed to run four virtualized instances, and the Data Center edition provides unlimited virtualized instances.
So we've really structured out licenses to be friendly and focused on virtualization.
Q: What about making it easier to package the OS and application rather than tying the OS license to a physical server?
Muglia: You've got to connect a license to something, and we looked at all the things to connect it to.
The way customers use virtualized instances is they create images of operation systems and applications together and then they store those images in some form, then they move those things around and load them on physical devices.
The one thing people have been able to count is the physical devices, the servers themselves, so our licenses are connected to our devices, and customers are absolutely free to move an image from one device to another as often as they want. There's no limit on that. It's just that the number on the server indicates the number of licenses of virtualization they're allowed to run.
Q: Do you ever see licensing an OS without requiring a link to a specific physical server?
Muglia: It's tough, and I'll never say never. But what we find is that customers need to be able to count something, and the one thing they're able to count on for sure in the server world is the number of servers they've got. So it still seems like the best approach to us.
