Workload Adaptive Checkpoint Scheduling of Virtual Machine Replication

Checkpoint-recovery based Virtual Machine (VM) replication is an emerging approach towards accommodating VM installations with high availability, especially, due to its inherent capability of tackling with Symmetric Multi-Processing (SMP) virtual machines, i.e. VMs with multiple virtual CPUs (vCPUs). However, it comes with the price of significant performance degradation of the application executed in the VM because of the large amount of state that needs to be synchronized between the primary and the backup machines. Previous research improving VM replication performance focused primarily on decreasing the amount of data transferred over the network, while relying on constant checkpoint frequency.
