[Beowulf] [External] RIP CentOS 8 [EXT]

Wed Dec 9 05:59:11 UTC 2020

Hi Guys,

Im probably a bit late to the party. What is going on with CentOS? As I am not quite understanding whats happening.

To be fair I am at the point where I am running through my mind the creation of my own distro based off fedora/Centos Stream (once I know what it is)

For me the biggest thing for sticking with Centos and RHEL derivatives is due to security features like SEL amongst other things as well there are some interesting developments that I need to try out such as podman (docker alternative)

Regards,
Jonathan

I don’t know how often we ever actually used Red Hat support for RHEL itself.  Very rarely, I suspect.  Even before they hiked the price on us, I expect we effectively paid them several thousand dollars per support call.

Some of the other products, like RH OpenStack Platform, yes, but not for the OS itself.

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

I wouldn't be surprised if this causes Scientific Linux to come back
into existence.
It sounds like Greg K is already talking about CentOS-NG (via the ACM
SIGHPC syspro Slack):
