I cannot find a clear answer to that question.
All the answers lead to this: Red Hat providers technical support for their distro while CentOS does not.
Also, CentOS lags behind with the updates.
Are these the only differences?
Is there any difference in software? For example:
Does Red Hat have some specific embedded proprietary software, unlike CentOS?
Or does Red Hat have a modified Linux kernel or something in comparison with CentOS?
Could you describe any advantages of Red Hat over CentOS if the tech support is not needed?
