I am first-hand witness to Fortune 50 companies do an about-turn to their Linux strategy because it was very hard to maintain and operate a linux shop. It is a very different thing to run a few/niche linux servers in a large shop as opposed to run a large Linux shop.
Most of the popularity of Linux drives from the fact that Big-iron is/was on it's way out of the Datacenters after the dot-com bubble burst.
Horizontal scaling on Intel/like(Cheap/commodity) hardware called for something that would run on it ergo -- Linux, given that it was a unix-clone, especially when the other choice was *blech* windows!!
That has changed significantly since Sun started serious support of x86/x64 with Solaris 10. Try running your favorite flavor of Linux through a gamut of benchmark tests (try sysbench if you don't have anything else to run) and then run same benchmarks on Solaris 10 on a Sun 4600 M2 (8 quad-core AMD).
You'll see the difference. Linux doesn't scale.
Also out of the top 500 Super computers in the world 427 run Linux, 0 run solaris. 5 run Windows 2 run Mac OS, 1 is BSD based and 25 are UNIX (Mostly AIX cause IBM dominates the super computer market) and 40 are mixed mostly Linux and proprietary. So we can see where the world is going when it comes to high end computing and number crunching, Linux and real time Linux. And you would think that something like BSD or Solaris would rule this market esp with BSD being open source and so called so much better then Linux?? But BSD and Solaris with ZFS and DTrace are not even a BLIP on the super computer landscape??? I wonder why?
Grid computing relies on running multiple nodes on cheap/smaller hardware platforms (scale by number). So you can have a huge super-computing grid of 2-cpu systems running linux (same reason as given above).
Why aren't people switching over to Solaris?
They are.
