The big thing nobody seems to be pointing out is that the whole Amazon upgrade story seems to PROVE that the cost of the OS is basically meaningless compared with the total cost of ownership.
Linux zealots love to scream that Linux is free, and therefore cheaper than Windows. Seems obvious, right? Wrong. There are very few cases where the TCO of Linux is lower than a Windows based setup. (On a side note, Macs have the lowest TCO for many situations, which, if anything, shows that you can't use just cost to determine the best upgrade path.)
In the original article (which, by the way, they have CHANGED to remove the obvious implications of my next point) they mentioned that the cost of moving from Unix to Linux is about the same for moving from Unix to Windows, aside from any software migration. Clearly, the cost of porting an application from Unix to Linux is far less than porting that same app to Windows. Think about that statement. If the cost of moving from Unix to Linux is ABOUT THE SAME as moving from Unix to Windows, that means the costs of the operating system is insignificant in the TCO. Linux is free. Windows is not. If the costs are the same, the costs of the OS don't really matter.
Funny how nobody on Slashdot, or in the article for that matter, pointed that out? Linux zealots scream about how free Linux is, and as it turns out, it's far from free.
Now, as far as the TCO comparisons, they seem to be BS. It's well known that starting from scratch, the TCO for a Windows infrastructure is far less than most commercial Unix distributions - especially Solaris. Solaris has a huge TCO. So the comparison they made, saying that Unix and Windows have about the same TCO, must have been made including the costs of porting all those existing Unix applications to Windows. This is a MASSIVE cost, and it isn't really a fair comparison.
If Amazon had been running Windows from the start, I'm willing to bet they would have saved considerably more money over Solaris to begin with. If you then factor the cost of porting apps from Windows to Linux, it would have made that move cost prohibitive.
So, the idea that the Amazon story shows Linux as a better alternative to Windows, just as Paul said, is baloney.
