Since mid-2006 and starting with RHEL version 4.4, which is formally known as Red Hat Enterprise Linux 4.0 update 4, Red Hat has adopted a version-naming convention identical to that used by CentOS (for example, RHEL 4.5 or RHEL 6.5).
Nekatera podjetja za gostovanje se zanesejo na CentOS v kombinaciji z nadzornimi pulti, kot je denimo cPanel.
