Web server clustering

In this chapter, we describe how to add additional Web servers for our WebSphere Commerce instance. We also show how to configure IBM WebSphere Edge Components Load Balancer to distribute HTTP requests between the Web servers and monitor the Web servers to be able to detect outages and automatically stop routing traffic to failed Web servers.

We also show how Load Balancer can be made highly available using a primary and a backup server that are able to monitor each other by exchanging heartbeat messages.

Figure 11-1 highlights the nodes that we configure in this chapter.
