Editing Red Hat Network (section)

== Architecture ==
In the basic subscription model the information about a managed host is stored on Red Hat's servers, and updates get downloaded directly from those servers as well. For an organization that manages multiple machines this is inefficient bandwidth-wise. Red Hat offers a [[proxy server]] (Red Hat Network Proxy) that once installed at a site allows machines to securely download updates locally. Advanced [[Application lifecycle management|lifecycle management]]; provisioning features, like bare metal PXE boot provisioning; and monitoring features (e.g. centralized CPU and disk usage) cannot be done over the Internet to the hosted RHN servers. These features require a RHN Satellite Server running locally. {{As of|December 2009}} the RHN Proxy Server costs $2,500 annually, and the RHN Satellite Server costs $13,500 annually, which includes the license for the embedded [[Oracle Database]].<ref>{{cite web|url=http://www.redhat.com/red_hat_network/faq/ |title=Network Satellite FAQs |publisher=Red Hat |date= |accessdate=2012-10-13}}</ref><ref>{{cite web |last=Gilbertson |first=Scott |url=http://www.redhat.com/magazine/010aug05/features/rhn_overview/ |title=What is Red Hat Network? |publisher=redhat.com |date=2005-08-10 |accessdate=2012-10-13 |url-status=dead |archiveurl=https://web.archive.org/web/20121014194650/http://www.redhat.com/magazine/010aug05/features/rhn_overview/ |archivedate=2012-10-14 }}</ref><ref>{{cite web|url=http://www.redhat.com/red_hat_network/architecture_comparison/ |title=Enterprise Linux management &#124; Compare architectures |publisher=Red Hat |date= |accessdate=2012-10-13}}</ref>
