If you have enabled load balancing when creating an AS group, perform the operations provided in this section to add a load balancer to your AS group.
AS automatically adjusts the number of instances in an AS group according to application traffic. The load balancer added to an AS group distributes application traffic to all instances in the AS group when an instance is added to or deleted from the AS group.
For instructions about how to create a load balancer, see Elastic Load Balance User Guide.
