Red Hat Update Infrastructure vs Satellite

My company is building a Cloud offering and is either in negotiations with RH to become a Red Hat Certified Cloud Provider or may have completed those negotiations. As part of the RHCCP program, we will "get", and  be required to use, the Red Hat Update Infrastructure (RHUI). In addition to our anticipated cloud offering, we also have numerous RHEL servers (standalone) used internally for various purposes.

Do we need to run both RHUI and Satellite to keep our RHEL servers (both cloud and non-cloud) patched or can RHUI be used for both, technically and legally? It would appear that a RHUI CDS could support our standalone infrastructure with proper key management and firewall management.

Would the only concern be that RHUI access would cease if the RHCCP relationship ended?
