To configure BlackBerry® MDS Integration Service high availability, you can install multiple BlackBerry MDS Integration Service instances in a pool and use a hardware load balancer to permit BlackBerry MDS Integration Service clients to access the available instances.

When you configure a hardware load balancer, you must configure a DNS name as the name of the BlackBerry MDS Integration Service pool in the DNS server. The DNS name must map to the IP address of a virtual server that is a component of the hardware load balancer. BlackBerry MDS Integration Service clients must distribute initial messages equally across all BlackBerry MDS Integration Service instances in the pool using the DNS name.

You must configure the hardware load balancer to monitor the connections from the BlackBerry MDS Integration Service clients to the BlackBerry MDS Integration Service instances in the pool and manage the pool dynamically based on the availability of the BlackBerry MDS Integration Service instances.
