Microsoft and Red Hat Team Up On Virtualization
mjasay writes "For years Microsoft has insisted that open-source vendors acknowledge its patent portfolio as a precursor to interoperability discussions. Today, Microsoft shed that charade and announced an interoperability alliance with Red Hat for virtualization. The nuts-and-bolts of the agreement are somewhat pedantic, providing for Red Hat to validate Windows Server guests to be supported on Red Hat Enterprise virtualization technologies, and other technical support details. But the real crux of the agreement is what isn't there: patents. Red Hat has long held that open standards and open APIs are the key to interoperability, even as Microsoft insisted patents play a critical role in working together, and got Novell to buy in. Today, Red Hat's vision seems to have won out with an interoperability deal heavy on technical integration and light on lawyers."
...or, more than likely, this.
...Why you would run Windows on top of Linux, given not only the stability history but also since now there are now FOSS alternatives for almost anything Windows can provide, without taking a huge hit to the "total cost of ownership".
Two words: Microsoft Exchange.

Even if that were true, in practice companies don't just swap out production environments because alternatives potentially exist. What works well for you may be problematic in even a slightly different environment. Others have mentioned apps for which OSS interoperability isn't there yet, and I'd add Group Policies and other AD centric tech to the list (although I admittedly haven't checked out recent versions of Samba lately, so maybe I'm wrong on that). I'm as big of an OSS advocate as there is, but part of advocating effectively is knowing where limitations exist and dealing with them rationally rather than sugar-coating them. I agree with the gist of what you're saying though, and there are a lot of shops that could lower TCO by exploring the alternatives.
Don't you have someone you'd die for?
