Describes the state of a Classic load balancer.
If you specify a load balancer when creating the Auto Scaling group, the state of the load balancer is InService.
If you attach a load balancer to an existing Auto Scaling group, the initial state is Adding. The state transitions to Added after all instances in the group are registered with the load balancer. If ELB health checks are enabled for the load balancer, the state transitions to InService after at least one instance in the group passes the health check. If EC2 health checks are enabled instead, the load balancer remains in the Added state.
