Ehhh... what? The Fedora Project
has corporate sponsorship from Redhat Inc.
but officially and properly speaking the Fedora distribution
itself (by the way, it's not Fedora Core anymore) is not a product of Redhat Inc.
The biggest differences are:
1) Community support (Fedora) versus paid support (Redhat)
2) Release cycle: Fedora releases every 6 months and a given version is (supposedly) only supported for about 13 months, Redhat is supported for years
3) Software stability: Fedora is a sort of testbed for bleeding-edge software (but can be made to work in production environments if you're dedicated); Redhat is specifically geared to production environments and contains tried-and-true software and feature implementations
EDIT: Though Fedora and Redhat have similar init structures and such from a technical standpoint, they're very different in terms of software stability and feel. CentOS is much closer to Redhat in terms of features and software versions.
