In this paper we have presented the model of clustering using Heartbeat and implemented with Virtualized environment. . For making a machine to be virtualized, the hardware must endow with virtualization capabilities we believe that we understand what makes the websites unreliable; the key to build a more reliable website is to make a cluster. Clustering is typically transparent from the clients as well as developers, perk up the system availability to the online users , as the failed server will automatically pack up and the users will automatically switched at that particular instant to the another server. Heartbeat is an open source portable tool for clustering.
