What distribution is most used in production environment - STONANSH

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.
@Anticorp @lemmy How do you figure? My understanding is CentOS is based on RHEL, not Ubuntu.
