I think it has mostly to do with user support. The biggest innovation on
moving from Red Hat Linux to Red Hat *Enterprise* Linux was the addition
of user support. Corporations like having someone to call when something
goes wrong. No one wants to hear "read the source" when the corporate
mailserver is down and 5,000 employees are no longer productive.
Red Hat providing user support was actually a big deal for the Linux
community. In the early days of Linux, many 3rd parties tried to make
Linux acceptable to corporate users by providing Linux support services,
but they never really caught. Probably because they weren't tied to a
particular distro, so they weren't perceived as as "expert" as when the
vendor itself is providing support.
On top of that, Red Hat worked with hardware and software vendors to get
them to support their products on Red Hat. It wasn't long after RHEL was
introduced that you started seeing hardware and software advertising
that it was supported on RHEL.
Combine these two, and you have a recipe for success: People are more
likely to use a version of Linux that comes with user support and that
they know is supported by the hardware/software they use.
To this day, I rarely see hardware/software advertised/documented as
supporting anything other than RHEL. Fortunately, many of those vendors
would treat CentOS and Scientific Linux the same as RHEL for support
reasons. At least that has been my experience.

Dear all,
what I never understood is: why are people not using Debian?
I done some cluster installation (up to 100 or so nodes) with Debian, more or
less out of the box, and I did not have any issue with it. I admit, I might
have missed out something I don't know about, the famous unkown-unkowns, but
by enlarge the clusters were running rock solid with no unusual problem.
I did not use Lustre or GPFS etc. on it, I only played around a bit with BeeFS
and some GlusterFS in a small scale.
Just wondering, as people mentioned Ubuntu.
All the best from a dark London

It sounds like Greg K is already talking about CentOS-NG (via the ACM
SIGHPC syspro Slack):
