Almost always use Ubuntu in production. Also a bit of Centos at one point.
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.
I'm seeing a lot of very interesting answers but I'm wondering what you mean by "production environment".
Do you mean VFX Production? (English not my first language so if "production" is used in different industries, well, I didn't know).
I'm new to the industry and worked for small companies that don't use Linux. But my VFX peeps use Rocky, Mint, and Ubuntu ( stronger preference for Rocky in studios).
In IT in the US, "production" is commonly used to refer to systems that support actual business operations. In other words, it's as opposed to "development" or "testing" systems.
Thanks! So I gather the default is IT and not VFX, fair enough. It makes sense.
You're welcome! Yes, I believe so.
Ubuntu, RedHat, AWS Linux, Arch. Honestly distros in production are pretty similar since they're all headless and pretty pared-down. If you just know the logistics of a few package managers and init systems you'll be good.
100% sure its Debian.
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.
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.
