Linux patching for Cloud Servers with the Managed Operations service level

Linux patching comes directly from vendors or distribution communities. The exception is Red Hat Enterprise Linux, which feeds updates through a data center–specific proxy server. The proxy server’s authoritative data is the Managed Red Hat Network server. Patching delays in a Managed Red Hat Network server also cause update delays in the proxy servers for the Managed Operations service level. For example, the upgrade to Red Hat Enterprise Linux 5.5, the fifth update release to Red Hat Enterprise Linux 5, was delayed for several months after it was released by Red Hat.

This table states the patching mechanisms and Rackspace-specific servers used in Managed Operations for different distributions. In the patching server URL, substitute the data center code, such as dfw1 or ord1, for {dc}.
