Patent attributes
A secure containment enclosure such as an equipment rack is disclosed that includes an electronic locking system. The electronic locking system locks and, upon receipt of a valid credential to a credential input device, unlocks an access door to the secure containment enclosure. The electronic locking system locks the access door during normal operation, and is prevented from unlocking the access door during normal operation and for a predetermined period of time after the secure containment enclosure is powered off to ensure that all data on electronic devices in the secure containment enclosure is erased. Other security features include storage encryption, network encryption, preventing administrative logon access to customers' compute nodes, and dedicated instances in which only virtual machines from specified customer accounts can be located on the same electronic device.
