Configure an External Load Balancer
You can use your own load balancer to uniformly distribute the traffic from AWS target VMs to V Series 2 nodes. The load balancer distributes the traffic to the V Series 2 nodes and the GigaVUE-FM auto-scales the V Series nodes based on the traffic. GigaVUE-FM creates a traffic mirror from the target VMs to the load balancer that all the targets must have the same traffic load balancer destination. Load balancer forwards the traffic to the V Series 2 nodes and the AWS Auto Scaling group monitors the load of all V Series nodes. AWS Auto Scaling group can add or remove nodes if the traffic load is heavy or low.
You can configure an external load balancer through AWS and GigaVUE-FM, Refer to the following sections for more details:
