CentOS went from being a “bug for bug” clone of RHEL to being upstream of RHEL ( the place RHEL gets branched from ). That means you can no longer use CentOS as a 100% clone of RHEL that allows you to avoid paying for RHEL if what you need is exactly RHEL. CentOS Stream is still available and still does everything RHEL does ( more really since the software will be newer ) but no longer guarantees bug-for-bug compatibility with RHEL. So it is a real alternative if you just want the functionality but not an option if what you really require is guaranteed compatibility. SUSE is offering a 100% bug-for-bug RHEL compatible distro along with commercial support. It costs $25 per server with a $2500 minimum spend.
