From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

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.

It really depends. I work for a large company and we use Ubuntu, Oracle, RedHat, and SLES. We were moving from Oracle to Ubuntu but now we are going back to RedHat.

Currently we deploy like this: Ubuntu: PostgreSQL, web servers, some engineering workstations, and big data Oracle & RedHat: web servers, security applications, and network systems

So just having a fundamental understanding of Linux and you will be fine SUSE: SAP and HR software

What's the reason if I may ask why they are moving to Red Hat instead?

Mostly cost. We used to run a lot of Oracle databases and they have become extremely expensive to keep running. So we are migrating to PostgreSQL. The servers were getting migrated to CentOS but now that RedHat fucked that distro we are going back to RedHat. Part of that deal is switching from chef to Ansible. So to save costs we are consolidating to a single vendor.

Oracle DB are sucking a lot of money, but they fork RHEL for free...(well it is open for everyone), they offer more expensive contract on top of Oracle DB, what a free estate.. haha... Nice work ORACLE... :/
