What's the thought process behind buying commercial support for a free, binary-compatible RHEL clone, instead of just paying for Red Hat support? Is the calculation that the once-in-a-blue-moon call to a commercial Rocky Linux support vendor when your server catches fire would still be cheaper than the cost of a normal RHEL license?
Disclaimer: I'm a former Red Hat employee, but only speak for myself. I'm also going to speak very frankly. You got it. From the customer side support from them is cheaper than Red Hat's (sometimes much cheaper). From the supplier side, they don't have to bear much (or any) of the cost of development (beyond infra hosting and re-branding), so they can beat Red Hat's price very easily. I personally find that gross and…
Having consultants out there using CentOS/Rocky/whatever gets these "not a good fit" customers burden off Red Hat, which is probably an advantage to them. I operated what amounts to a "phone a Linux friend" service for ~18 years, and that sort of help just doesn't really fit into Red Hat's offering.
It's nice in many ways to be able to disconnect from the licensing model and just be able to deploy Linux boxes, but still get help when you need it. I recall one conversation about Red Hat licensing related to a machine I was installing for a client named "The Fedora Project" that went like this:
"I assume you'd like me to put Red Hat on there?" "Yes." "Can you provide me with a license key to use on it?" "Uhhh. Just go ahead and install CentOS".
