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.
Started with RHEL years ago, migrated to CentOS to get away from the license fees etc. Have since moved to Amazon Linux since we subsequently migrated everything to AWS.
