The External Load Balancer Mode is intended to work with networking environments where LVS load balancing is not supported or an external load balancer is preferred.
Configure an InterWorx Cluster by adding cluster nodes. Once cluster nodes have been added navigate to NodeWorx -> Clustering -> Load Balancing page on the Cluster Manager. Set the “External LB Mode” radio button to “On” and click “Save”.
This will update existing virtual hosts on the cluster nodes to now listen on the primary network interface IP address rather than the loopback or tunnel device normally used for LVS-DR or LVS-TUN.
At this point, you will now configure the external load balancer. External load balancers tested with this setting include HAProxy, AWS Elastic Load Balancing, and Google Cloud Load Balancing. Configuring these services are outside the scope of this guide.
