A system for event-driven live migration of applications between two or more servers. Primary applications runs on primary hosts and one or more replicated instances of each primary application run on one or more backup hosts. Event driven live migration is provided through a combination of process replication, logging, barrier synchronization, reliable messaging and message playback. The event driven live migration is transparent to the application and requires no modification to the application, operating system, networking stack or libraries.
