Dynamics AX 4.0 SP1 Clustering and Load Balancing

Set up load balancing

Add AOS instances to a cluster and run the cluster without a load balancer.

If you set up a cluster without a load balancer, you can use client configurations to set clients to connect to one or more AOS instances that have load balancing enabled. If an administrator needs to remove a computer from the cluster, and one or more client configuration is pointing to it, the client configuration must be updated. No additional hardware is required for this topology.

Add AOS instances to a cluster and configure one or more AOS instances to be a load balancer.

If you set up a cluster with a load balancer, you must use client configurations to set clients to connect to the AOS that has been set as the load balancer. You can then add and remove instances from the cluster without needing to update client configurations. Additional hardware may be required to set up a computer as a load balancer.

Add AOS instances to a cluster
Open the Server Configuration utility (Start > Control Panel > Administrative Tools > Microsoft Dynamics AX Server Configuration Utility).

Verify that the currently selected (AOS) instance and configuration are the ones that you want to modify.

Select Make this AOS instance part of the load balancing cluster.

Set a value for the maximum number of client sessions that the AOS instance will accept.
