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.

Mostly mission critical server that I deployed in the past, all use RHEL/Clones because their LTS, and stability across packages version.
If for hobbyist, it's Ubuntu. I think you need to learn more about ansible, container/podman/openshift, and SDN for work. Nowdays, there are some use APT in production, but mostly they switch to dnf because dnf have better way to do downgrade, undo, redo, and config package in production.
This applied mostly for ERP project such as SAP Hanna, SQL Server, DB2, etc... Like it not, Red Hat Dwindling isn't now, probably 5-10 years ahead, but I'm not sure, as mostly rant about RHEL are in Community. I do know regional linux user group in Indonesia, some are leaving EL group, but they still can't rip apart most mission critical server on top of RHEL/Clones... so it's still worth learning RHEL/Clones, and use Fedora for day 2 day task, and learn ubuntu, as well ubuntu pro, for learn deploying critical production server.
Debian and Ubuntu are near, and ubuntu is derived from debian, but if you talk spirit, they are different... If you are conscious about what Red Hat do, stay away from it, but if you are working in corporate, you can't go without learning it.
Fun fact. At Heineken Netherlands we also happen to use SAP. the backend is using SLES-11 how ever
Well SLES is quite lean near RHEL, they have same rpm/dnf pkg manager, which is near RHEL, but not B2B compatible, or even ABI compatible, but SUSE is okayish, but I don't know, many corporate that work for aren't keen using it haha.. 😂
Well at least, seems Europe have different kind of market, but having competitor is driving industry forward isn't it?
Well SAP is from German, but I don't know why it's much for popular on top of RHEL, rather than other. I do know Ubuntu support SAP, but never seen one in the wild in Asia Pasific. 😂
Also I remember IBM Watson is on top SLES? 😂😂 Dunno if IBM replace it with Red Hat? Haha.. 😂
