It depends on the use case. If all you want is a free, reasonably stable
version of RHEL, Centos stream might just be good enough.
If your goal is to support software that wants RHEL, this could be hit or
miss, as you'll always be running on an approximation of RHEL. You could
say you should always have been just buying RHEL if it's that critical, but
it's now that much less optional.
I'm also really curious to see what's going to happen to the various black
box appliances out there that currently run on CentOS, like Aruba
Clearpass, Aruba wireless controllers, and the Juniper QFX switches. I
doubt they'll want something stablish like CentOS Stream, so they most
likely have three basic choices.
1. Run on CentOS 7 for as long as they can get away with it, and hope
something better appears in the meantime
2. Work out a licensing deal for RHEL, and pass along the costs to the
3. Switch to an alternate distro like Ubuntu LTS
The next year is going to be interesting for more than a few vendors...

This might not be as bad as it initially sounds.
Centos Stream will
consist of rolling updates that start from what will become each RHEL
point release to what will become the the next RHEL point release, so
for example from RHEL 8.1 to 8.2 to 8.3 etc. In fact, Centos 6, 7,
and 8 already is a "forced" minor upgrade every quarter or so since
they stop supporting x.y after RHEL x.y+1 comes out and your normal
system yum updates just migrate you to the newer x.y+1 anyway. This
is in contrast to how RHEL itself works, or how Scientific Linux used
to work, where you actually have to take explicit action to upgrade to
a new point release either using new install media or manual "yum"
commands. See for example:
And here is what one of my Centos 7 systems looks like:
release 7.9.2009 (Core)
rpm -qf /etc/centos-release
rpm -qi centos-release
Version : 7
Release : 9.2009.1.el7.centos
Install Date: Thu 03 Dec 2020 07:27:24 AM EST
See how the Centos 7.9.2009 release package was installed this month?
Previously, I had older versions of that package:
sudo grep centos-release /var/log/yum.log*
/var/log/yum.log:Nov 13 08:46:49 Updated: centos-release.x86_64
/var/log/yum.log:Dec 03 07:27:24 Updated: centos-release.x86_64
/var/log/yum.log-20181204:Jul 30 14:47:20 Updated:
/var/log/yum.log-20181204:Aug 14 12:15:35 Updated:
/var/log/yum.log-20181204:Oct 10 05:45:04 Updated: centos-release.x86_64
/var/log/yum.log-20181204:Dec 04 07:19:18 Updated: centos-release.x86_64
/var/log/yum.log-20200428:Jan 08 09:08:24 Updated:
/var/log/yum.log-20200428:Apr 28 07:47:22 Updated: centos-release.x86_64
So over the years, this server got upgraded automatically from Centos
7.5 to 7.6 to 7.7 to 7.9. I have nightly automatic "yum updates"
turned on, so it just gets updates as they come out and I reboot the
server once every so often so the updates get fully applied (new
kernels, new shared libraries).
The difference with Centos Stream is you'll get updates continually
/before/ RHEL releases it eventually as a "snapshot in time" called
RHEL x.y+1. Sure, they won't be as heavily tested as RHEL point
releases, but if you really need/want that, then you can either buy
RHEL or stage your Centos Stream updates from TEST-->STAGE-->PROD,
and/or stagger them across your PROD systems to minimize impact.
