Linux Patching for Cloud Servers 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's authoritative data is the Managed Red Hat Network server. This means that patching delays in Managed Red Hat Network server also delay updates in Managed Operations Service Level. For example, Red Hat Enterprise Linux v5.5 was delayed for several months after it was released by Red Hat.
