Enhanced Load Balancing

A cluster of two or more SAP Mobile Server nodes provides some degree of load balancing, but load balancing can also be applied to both client connections and EIS connections, to improve performance and efficiently use resources in the SAP Mobile Server cluster.

There are two load-balancing mechanisms you can use with the SAP Mobile Server cluster:

Relay Server – an SAP software product that acts as a reverse proxy server for client devices communicating with SAP Mobile Server.
Load balancer appliance – a third-party product, such as an L4 network switch, can be used for both client and EIS connections.

Note: You cannot use Relay Server on EIS connections.

Client Load Balancing
Client load balancing improves capacity and performance of the SAP Mobile Server cluster when it is servicing mobile client requests.
Client Load Balancing with BES
You can apply load balancing to connections between BlackBerry Enterprise Server (BES) and SAP Mobile Servers in a cluster.
EIS Load Balancing
EIS load balancing improves the capacity and performance of the SAP Mobile Server cluster when it services data change notification (DCN) or SAP® Data Orchestration Engine Connector requests from the back-end enterprise information system (EIS).
