CentOS - What is the current opinion here?

Is anyone using CentOS stream in a production scenario?
I don't but I would, but then I already use Fedora in production.

What is the current state/opinion here about migration?
That answer is, as always, what is the workload? The workload drive the needs of the OS.
Obviously a simple website workload can run on damned near anything.

@jaredbusch It's an Ansible server.

So I have 1 server that needs migrated from CentOS8. What is the current state/opinion here about migration? Ubuntu is a clear choice, and most likely the path I will take, but wanted to get some other opinions as well. Is anyone using CentOS stream in a production scenario?
I've looked through here:
https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html#installing-ansible-on-rhel-centos-or-fedoraI don't see any specifications for cores/threads and storage requirements which I find odd? Is there a *NIX assumption or something about system resources?
Ah ... as I get closer to a more accurate set of search terms the search foo increases ...
https://docs.ansible.com/ansible-tower/2.2.2/html/installandreference/requirements_refguide.html
Anyway, my though/search strings aside, we're doing Mastodon on Ubuntu 20.04 LTS with not an issue other than tweaking scripts that were written for an earlier version of Ubuntu.
Ubuntu is my suggestion for an OS.

You can install ansible on almost anything.

My opinion is that a company should pick one linux OS as their standard and stick to that for everything possible.
It doesn't matter what it is, because it will all work equally good. What matters are other things.
At work we run Debian because we want a non-commercial, community supported OS that is stable and has a huge user base.

But this is the thing, not all applications are designed to run on various operating systems. So you do not always have the luxury.

Like Jared, I, too, use Fedora in production. CentOS Stream shouldn't be a problem, if you're currently running CentOS 8. For Ansible, I'd run it on Fedora, but I tend to standardize on Fedora and the RHEL ecosystem.

That's true, you have to run what works. But most of the time you can stick to one OS.

I have a lot of CentOS Stream in production for customers who don't have a clear understanding of release and support schedules and need the smoke and mirrors of the CentOS marketing to make them feel better. On technical grounds, I would never deploy it by choice. It isn't terrible, but it's a pretty goofy idea that I do not feel has any reasonable place in production. It exists to placate politics where middle managers who don't know IT need to inject a truly foolish opinion.

Right, if you think you want CentOS Stream, Fedora is like the production ready improvement on it. It's not that Stream is bad, it's that Fedora is better in like every way, while being essentially the same basic product. Stream is just a ridiculous half-assed byproduct of Fedora. If you love the ecosystem, stick with Fedora. I use about half Fedora and half Ubuntu. Both are great.

I wrote about this in my book. It feels good, but I think it is generally impossible. And once you have variation, attempting homogeneity falls apart in value. You can generally get by with a few different OSes with minor variation. For us that means Ubuntu, Ubuntu LTS, Fedora, Debian, and CentOS Stream are required in some combination. We can't standardize on any one because we have a workload here or there that requires something "niche". When we have the choice, we are using Ubuntu first. Then Ubuntu LTS, then Fedora. But it's always workload based and going with just one wouldn't be practical unless we were only running software that we wrote ourselves exclusively.

Not that we've found. Finding an environment where you are running Linux, and can avoid all variation is pretty rare, I think. So many apps only work on Ubuntu XOR CentOS. It's a mes out there.

Ok, I will, just look at my home lab! Fedora, Ubuntu and Debian because things either only run or run much better on different ones.

Say what one wills about Microsoft Windows, this conversation makes it clear that things are relatively homogeneous on that side of things. All things being equal and the company is not stuck on some encapsulated AS400 app or something.

I'm curious about what workloads you are thinking about.
I try but I can't think of any major application that doesn't run on both debian and redhat based distros. I'm not counting appliances here, because the OS under the hood is fixed and not something you can select.
-
Fedora seems like a logical choice. Fedora it is!

It seems that way, but I feel like Linux apps tend to be almost always for current versions of the OS. At least production ones. But on Windows the amount of "we only support really old versions" is really high (of course, you can argue, anything that does that can't be production, right?)
But really, the issue is that Windows is an OS and Ubuntu is an OS. So there is no fracturing. The thing that gets weird is when you look at a large family of similar operating systems and compare them to the single OS of Windows. Sure, it seems fractured. That's because we are comparing an orchard to a tree. OS to OS, there is no fracturing.
There's no direct comparison. In the Windows world, though, you get "only licensed for Server" or "only runs on desktop" version issues that create similar fractures even on a single OS. We are constantly talking to clients about having gotten the wrong OS version for their needs. That never happens with Linux because there aren't those licensing limits or version in that way. It's a totally different style of problem, but it exists there, too.
