You can apply load balancing to connections between BlackBerry Enterprise Server (BES) and SAP Mobile Servers in a cluster.
When you deploy an SAP Mobile Platform system to support BlackBerry device users, BES treats the SAP Mobile Server as a back-end enterprise application. Connections from BES are treated as client connections by SAP Mobile Server.
To implement client load balancing on connections between BES and SAP Mobile Servers in a cluster, you can deploy either a proxy server, or a load balancer appliance.
The load-balancing mechanism between BES and SAP Mobile Server is deployed on the internal LAN.
If your SAP Mobile Platform system supports both BlackBerry device users and users of other device types, you can apply load balancing to both BES connections and other client connections.
