CLUSTERING DEFINITION (continued): …  in some cases. One of the main ideas of cluster computing is that, to the outside world, the cluster appears to be a single system.A common use of cluster computing is to load balance traffic on high-traffic Web sites. A Web page request is sent to a "manager" server, which then determines which of several identical or very similar Web servers to forward the request to for handling. Having a Web farm (as such a configuration is sometimes called) allows traffic to be handled more quickly.Clustering has been available since the 1980s when it was used in DEC's VMS systems. IBM's Sysplex is a cluster …
