Dynamic database replica provisioning through virtualization
Sergey Savinov, Khuzaima Daudjee · 2010
Data replication is a popular technique for providing good performance, high availability and fault tolerance in distributed database systems. We investigate data replication in a virtualized environment, focusing on provisioning when the master database server is heavily loaded or when it fails. We show that using virtualization, provisioning of the backup replica can be done quickly, thereby reducing service interruption time. We also show that this provisioning can efficiently support load balancing and failover in a virtualized environment.
