Red Hat Enterprise Linux (RHEL) is a Linux distribution focused exclusively on the corporate segment, giving users various functions at the level of security, performance, stability and performance, which is why it is popular in the server segment..
RHEL recently launched a beta version of the RHEL 8.2 edition which will be officially launched in a few months. This RHEL 8.2 Beta version allows you to register the system, attach RHEL subscriptions, as well as install from Red Hat Content Delivery Network (CDN) before installing the package.
Something to keep in mind is that the size of the ISO image has been reduced to a size of only 600 MB facilitating its portability..
