Changes

CentOS is a testament to the unique nature of open source software because it is actually 100% compatible with Red Hat Enterprise Linux. In fact, CentOS is essentially Red Hat Enterprise Linux with the Red Hat branding and logos removed. CentOS is available for free so you get the power and stability of Red Hat Enterprise Linux without having to purchase it.

Of course, CentOS lacks the dedicated and guaranteed technical support that you get by buying a Red Hat subscription. That said, CentOS is backed by a skilled and active community and I have yet to encounter a problem with CentOS that could not be resolved with the help of the experts who participate on the CentOS forums.
