Installing a clustered Sterling Configurator Visual Modeler implementation

A cluster provides an environment that supports higher performance and reliability than a single machine can. Typically, a cluster comprises two or more member machines that from the outside world appear to work as one machine: when users submit a request to the cluster URL, they are not aware of which machine in the cluster processes the request and returns the response.

The cluster URL is usually directed to a Web server that sits “in front” of the cluster: this Web server provides the entry point for users, and it is responsible for distributing the requests to cluster members as requests come in. The Web server acts as a load balancer and distributes requests using an algorithm to determine which cluster member machine should receive each inbound request.

The following figure illustrates the general cluster configuration.
