Last week\u2019s pact between Microsoft and Novell has led to widespread speculation over the long-term impact on the adoption of open-source software. Under the deal, the companies will work on ways to enable Novell\u2019s Linux distribution, Suse, and Microsoft\u2019s Windows operating system to work better together. They also reached a patent truce in which users of the other\u2019s software can\u2019t be sued for infringement, and Microsoft agreed not to sue noncommercial open-source developers. On Monday, Microsoft\u2019s Bill Hilf, general manager for platform strategy, spoke further about the deal with IDG News Service, addressing how Microsoft views its intellectual property relative to Linux.IDG News Service: How does Microsoft view open source?Bill Hilf: Microsoft does not compete with open source. We compete with open-source products that people sell. When we did the deal with JBoss [an open-source middleware company now owned by Red Hat], we found a few interesting stats. Half of their users were running on Windows. We also found after we did the deal, we sold more Windows server licenses. That\u2019s just fundamental good business. So when we get into the competitive debate, JBoss helped our Windows server business grow.IDG: There have been looming questions for years if Microsoft would file lawsuits over intellectual property contained in Linux. What is Microsoft\u2019s motivation with Novell?Hilf: This is an intellectual-property deal. There will be an overlap at some point between our intellectual property and open source that we have to resolve. We knew that. It was going to happen. It was just a question of when.We said let\u2019s put in place something that allows us to a) establish a process for how we can work with an open-source company on our intellectual property, b) do it in such a way that it can still work within the [GNU] GPL [general public license], and c) how do we do this in a way where we can clearly draw the line between the community developer, the noncommercial open-source community guy writing code and the commercial developer who is using open-source code. Doing one of those is easy. Doing two of them is actually hard but possible. Doing all three is very, very hard because one can contradict the other.IDG: What is the overlap between what Microsoft does and what the open-source community does?Hilf: We have the largest software patent portfolio in the world. With open source, we needed to have something in place where we knew that if our intellectual property was infringed upon, we had a framework in place to resolve that in an effective way. The terms of the agreement that relate specifically to what we call covenants for Novell customers are related to the fact that those customers will be deploying a variety of open source. We said there is a way we can cover that customer and still have value for our intellectual property. The second part is there is a large class of people in the community who are writing software for free and are not selling it and who may either intentionally or inadvertently step into that footprint of our intellectual property. What we are trying to do is draw the line between people who make money from this and people who don\u2019t. We needed to have the peace of mind both for the customers who are choosing to put this stuff into their environment as well as developers.IDG: It seems like a veiled threat to Red Hat users\u2014there\u2019s only one way to protect yourself legally and that\u2019s by using Suse Linux.Hilf: There\u2019s no threat. There\u2019s a fundamental premise that we need to have the market understand we have a substantial amount of intellectual property in the operating system space.IDG: Is Microsoft going to approach other open-source vendors?Hilf: Our door is open to anyone to do a similar deal.IDG: Why do this deal now rather than a few years ago?Hilf: We started on the general framework for this three years ago. The deal with Novell started about six months ago. There was just a lot of work we needed to do to understand the GPL side of it and not violate the GPL. We don\u2019t actually license patents in this agreement. There is no patent cross-licensing. We are saying we are providing coverage for Novell\u2019s customers from a Microsoft intellectual property perspective. That allows us to work with the GPL because the GPL is very specific about licensing of patents. That took a while to get to that point from a legal framework. IDG: How many customers do you think will run Windows on Linux or vice versa?Hilf: I believe the market now and even more over time is rapidly leaving the proprietary system space\u2014be it proprietary Unix, proprietary mainframe\u2014and they\u2019re taking advantage of x86 capabilities. There\u2019s two players: Windows and Linux. I think over the next 10 years it\u2019s going to be a Windows-Linux on x86 world for anyone buying a new server. There\u2019s not a lot of people lining up to say, "I\u2019m ready to go deploy Linux on top of Windows." I would say less than 10 percent of the market, but I would think in the future it will be a substantial part of the market.IDG: People look back on Microsoft\u2019s 2004 technology development deal with Sun Microsystems and ask now what came out of it. Will we look back two years from now and wonder what really came out of this deal with Novell?Hilf: We\u2019ve gotten a lot of reaction about that. There\u2019s actually a tremendous amount of work that we do with Sun at an engineering level, but it just doesn\u2019t get exposed. We made sure to put some important things in place that would be visible into this work like a joint lab. Also, we are putting a substantial amount of co-marketing into this. We\u2019ve learned from the Sun market reaction.-Jeremy Kirk, IDG News Service (London Bureau)Related Links:\n\nRed Hat Spins Novell-Microsoft Pact in Its Favor\n\nBeyond Vista (CIO editorial feature)\n\nLinux Advocates Wary of Novell-Microsoft Tie\n\nMicrosoft, Novell Team in Linux DealThis article is posted on our Microsoft Informer page.\u00a0For more news on the Redmond, Wash.-based powerhouse, keep checking in.Check out our CIO News Alerts and Tech Informer pages for more updated news coverage.
