Abstract
|
Proactive recovery of replicated services … Proactive recovery of replicated services is a novel approach that allows tolerating a potentially unlimited number of malicious faults during system lifetime by periodically restarting replicas from a correct state. Recovering a stateful replica requires a time-consuming transfer and verification of the state. During this time, the replica usually is unable to handle client requests. Our VM-FIT architecture harnesses virtualization to significantly reduce this service unavailability. Our approach allows recovery in parallel with service execution, and uses copy-on-write techniques and provides efficient state transfer support between virtual replicas on a host. upport between virtual replicas on a host.
