Is CentOS the upstream for Oracle Linux? Instead of which comes CentOS Stream and then the question is what will Oracle do? Would they even try to keep the old CentOS concept alive?
I'm pretty sure that OEL is derived directly from RHEL, particularly because OEL 8 shipped while CentOS was still figuring out how to deal with streams.
CentOS is how RedHat releases their sources in compliance with open source licenses (Presumably they're going back to releasing them as a consequence for this).
My familiarity with Amazon Linux is about 4 years out-of-date these days, but it was a RHEL/CentOS clone with a number of the core libraries like glibc being updated and maintained by Amazon on an independent life cycle.
Not really. You can use Alibaba Cloud Linux 2 like that if you want but why would you do that? Oracle Linux, CloudLinux, Debian or openSUSE Leap are better choices.
