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 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.

Famous quotes containing the word architecture:
“It seems a fantastic paradox, but it is nevertheless a most important truth, that no architecture can be truly noble which is not imperfect.”
—John Ruskin (1819–1900)
“And when his hours are numbered, and the world
Is all his own, retiring, as he were not,
Leaves, when the sun appears, astonished Art
To mimic in slow structures, stone by stone,
Built in an age, the mad wind’s night-work,
The frolic architecture of the snow.”
—Ralph Waldo Emerson (1803–1882)
“For it is not metres, but a metre-making argument, that makes a poem,—a thought so passionate and alive, that, like the spirit of a plant or an animal, it has an architecture of its own, and adorns nature with a new thing.”
—Ralph Waldo Emerson (1803–1882)
