I&#x27;m not clear what you&#x27;re asking...  Do you mean auto scaling the EC2 instances in the load balancer?  Or auto scaling the # of load balancers?  Or something else?<p>Of course the former is very common with Auto Scaling Groups [1] [2].  Then you can use round robin or session sticky routing algorithms in the load balancers.<p>(Apologies if I&#x27;m totally off-base for what you were asking.)<p>1: <a href="http:&#x2F;&#x2F;docs.aws.amazon.com&#x2F;AutoScaling&#x2F;latest&#x2F;DeveloperGuide&#x2F;AutoScalingGroup.html" rel="nofollow">http:&#x2F;&#x2F;docs.aws.amazon.com&#x2F;AutoScaling&#x2F;latest&#x2F;DeveloperGuide...</a><p>2: <a href="http:&#x2F;&#x2F;docs.aws.amazon.com&#x2F;AutoScaling&#x2F;latest&#x2F;DeveloperGuide&#x2F;as-scale-based-on-demand.html" rel="nofollow">http:&#x2F;&#x2F;docs.aws.amazon.com&#x2F;AutoScaling&#x2F;latest&#x2F;DeveloperGuide...</a>
