In Web Server Cluster (WSC), replication techniques are necessary when accessing data from multiple locations whether it is from a local area network environment or geographically distributed worldwide. In WSC, for the sake of availability and reliability when sharing or backing-up data, the best alternative would be to replicate a copy of the data in the server across network. Thus providing reliability and efficient services are our primary goals in designing a cluster architecture data replication scheme. However, the primary concern for the technique is not only to provide high availability and reliability but also to boost up the performance of data replication: to minimize the response times and to maximize the throughput. This paper proposes an algorithm of data replication scheme based on asynchronous replication in order to improve web server cluster system reliability. The proposed technique also manages to reduce to a very minimal response time while providing maximum throughput.
