I’ve come across Red Hat allot lately and am wondering if I need to get studying. I’m an avid Ubuntu server user but don’t want to get stuck only knowing one distro. What is the way to go if i want to know as much as I can for use in real world situations.
At this point? Probably Cent OS, since that’s what AWS uses. It’s a variation of Ubuntu. So if you don’t count it as separate, then definitely Ubuntu.
CentOS is an RHEL variant, not Ubuntu.
Amazon Linux 2 uses a mix of stream and Fedora IIRC.
Are you sure you mean centos? Centos is a rolling release of the next version of rhel.
