Red Hat Enterprise Linux version 8.0 has been out for some time and is available for testing purposes on RedHat's website. All you need to do to get it is create an account if you don't already have one, download the ISO and install it using your credentials. If you have previously worked with the 7.x branch of Red Hat Enterprise Linux or CentOS the installation process will be familiar to you since not much has changed.
