-- Attaches one or more Classic load balancers to the specified Auto Scaling group.

--
-- To attach an Application load balancer instead, see 'AttachLoadBalancerTargetGroups' .
--
-- To describe the load balancers for an Auto Scaling group, use 'DescribeLoadBalancers' . To detach the load balancer from the Auto Scaling group, use 'DetachLoadBalancers' .
