For the purposes of avoiding trademark infringement all RHEL clones go out of their way to avoid mentioning Red Hat, thusly Red Hat Enterprise Linux and all derived from its sources tend to get lumped together as “Enterprise Linux”

Sure, but what makes Rocky "enterprise"? Is it just marketing or can everything be "enterprise"? Is Windows not "enterprise"?

[kingaillas]

To me, being "enterprise" means shipping/supporting running enterprise functions on the OS. So things like network information services, databases, perhaps giving options of filesystems that can handle extremely large sizes, cluster support, added support from the vendor, etc.

Stuff that a typical desktop user probably won't run or use. Maybe they can if they really wanted to, but not the common use case.

>Is Windows not "enterprise"?

Funny you ask when Microsoft literally sells a version of Windows called "Windows Enterprise". https://www.microsoft.com/en-us/windowsforbusiness/compare

Find the differences between Windows 10 Home and Windows 10 Enterprise and that may help you understand what makes Rocky Linux also enterprise.

Rocky aim for “bug for bug” compatibility with RHEL.

Red Hat target RHEL to a conservative, enterprise audience who look for a long lived well supported operating system, Rocky (and CentOS before it) court the same audience.

The primary difference being that RHEL is a premium product differentiated by the Red Hat support, training and documentation offering.

Support in so far as Red Hat will work with you to troubleshoot your OS issues, and issue custom patches to the packages they supply that you’re encountering issues with etc etc.

Training in that Red Hat offer many training courses and certifications in the usage and deployment of their many software packages and collections (System Administration, Troubleshooting & Diagnosis, High Availability Cluster administration etc etc)

If you look at Microsoft’s offering for Windows server you’ll see many parallels in the offerings that Red Hat present.

Being based on Red Hat by way of CentOS, who's full name initial-ized as RHEL is "Red Hat Enterprise Linux"
