A transparent high-availability solution utilizing virtualization technology is presented. A cluster environment and management thereof is implemented through an automated installation and setup procedure resulting in a cluster acting as a single system. The cluster is setup in an isolated virtual machine on each of a number of physical nodes of the system. Customer applications are run within separate application virtual machines on one physical node at a time and are run independently and unaware of their configuration as part of a high-availability cluster. Upon detection of a failure, traffic is rerouted through a redundant node and the application virtual machines are migrated from the failing node to another node using live migration techniques.

Systems and methods of high availability cluster environment failover protection

A system is provided for rapidly synchronizing two or more processing elements in a fault-tolerant computing system. Embodiments of this system allow for the rapid synchronization of two processing elements through partial copies of the contents of memory associate with each processing element.
