PowerServer cluster is a feature provided by Appeon for implementing load balancing and failover with the Appeon plug-in. It will not interfere with the existing application server cluster, such as WebLogic, WebSphere, JBoss, or JEUS cluster.
For detailed instructions on configuring Apache with the PowerServer cluster, please refer to Tutorial 5: Configure PowerServer Cluster in PowerServer Mobile Tutorials. The instructions are exactly the same for both PowerServer Web and PowerServer Mobile.
