Linux, not Microsoft, the real winner of Windows Server on ARM
Cutting to the heart of it, it doesn't actually matter if Microsoft releases Windows Server for ARM. Windows isn't the future and even Microsoft knows it. The upcoming availability of SQL server on Linux is all the proof we need that the game is over and, in the data centre at least, Microsoft didn't win.
Quite frankly, there's nothing wrong with that. Legacy x86 Windows applications have been a millstone around the neck of the entire industry for ages now and its long past time they were relegated to a niche and left to quietly slip away into the night. What's interesting here isn't that Microsoft managed to take its existing code base, strip out some of the cruft and compile it on ARM. What's interesting is what Microsoft's experiment unlocks outside the Windows ecosystem.
