In Web Server Cluster (WSC), replication techniques are necessary when providing accesses to data at different locations. In WSC, when designing the cluster architecture, the elements of availability and reliability for cases of data sharing or backing-up data are given the top priority. This is to ensure that the response time and throughput is still within the acceptable range. In ensuring the values of response time and throughput have not surpassed the limit, thus the replication technique must be employed intelligently. The replication technique that is been proposed is based on asynchronous replication technique. In doing so, we have managed to improve the reliability of the web cluster system. We have also managed to control the response time to a very nominal value but at the same time able to provide utmost throughput.
