A method or apparatus detects a memory corruption of at least one portion of memory during run-time and corrects the memory corruption of the at least one portion of memory by replacing the at least one portion of memory with a backup of the at least one portion of memory. In this way, memory corruption can be corrected in a timely fashion while minimizing security risks.

Pipelined data replication for disaster recovery is disclosed. An example pipelined data replication method for disaster recovery disclosed herein comprises sending replicated first data from a primary processing environment to a secondary processing environment for backup by the secondary processing environment, the replicated first data being a replica of first data in the primary processing environment, processing the first data in the primary processing environment prior to the backup of the replicated first data by the secondary processing environment being confirmed, and preventing a result of the processing of the first data from being released by the primary processing environment until the backup of the replicated first data by the secondary processing environment is confirmed.

Methods and apparatus to migrate virtual machines between distributive computing networks across a network are disclosed. A disclosed example method includes establishing a data link across a network between a first distributive computing network and a second distributive computing network, the first distributive computing network including a virtual machine operated by a first host communicatively coupled to a virtual private network via a first virtual local area network, communicatively coupling a second host included within the second distributive computing network to the virtual private network via a second virtual local area network, and migrating the virtual machine via the data link by transmitting a memory state of at least one application on the first host to the second host while the at least one application is operating.

Methods and apparatus to migrate virtual machines between distributive computing networks across a wide area network

Methods and apparatus to migrate virtual machines between distributive computing networks across a wide area network are disclosed. A disclosed example method includes establishing a data link across a wide area network between a first distributive computing network and a second distributive computing network, the first distributive computing network including a virtual machine operated by a first host communicatively coupled to a virtual private network via a first virtual local area network, communicatively coupling a second host included within the second distributive computing network to the virtual private network via a second virtual local area network, and migrating the virtual machine via the data link by transmitting a memory state of at least one application on the first host to the second host while the at least one application is operating.
