We consider the use of a cluster of PC servers for Application Service Providers where applications and databases must remain autonomous. We use data replication to improve data availability and query load balancing (and thus performance). However, replicating databases at several nodes can create consistency problems, which need to be managed through special protocols. In this paper, we present a lazy preventive data replication solution that assures strong consistency without the constraints… CONTINUE READING
