Comment It was straight forward until IBM bought Redhat (Score 0) 280
The way CentOS and Redhat could be used together to power dev and production systems and not really be concerned about the differences was on a nice roll for awhile.
It's changed with CentOS being controlled by Redhat and now being made into another Fedora.
The licensing of Redhat Linux is more costly than Windows, so all in all, it almost feels like the day Oracle bought Sun Microsystems. Open source has become vastly more complicated, and easier to deploy at the same time. It makes the option of figuring out tough problems something one would prefer the vendor to handle, rather than wait and wonder about issues reported to the open source bug reporting system or mailing lists.
I'm not saying we'd be better off with commercial Unix, but that commercial Linux is going down the same high cost path we've seen before, and it will make choosing a distro to use in Enterprise with tight funds more of a challenge.
