Advantages

Hosting members of multiple clusters across one or more machines has the following advantages: Improved throughput

Using an appserver cluster enables the handling of more client requests simultaneously. Improved performance

Hosting cluster members on multiple machines enables each member to make use of the machine's processing resources. Hardware failover

Hosting cluster members on multiple nodes isolates hardware failures and provides failover support. Client requests can be redirected to the appserver members on other nodes if a node goes offline. Application software failover

Hosting cluster members on multiple nodes also isolates application software failures and provides failover support if an appserver stops running. Client requests can be redirected to cluster members on other nodes. Process isolation

If one appserver process fails, the cluster members on the other nodes are unaffected.
