Take advantage of automatically scaling and load balancing instances when you deploy applications using Cloud Application Manager in AWS EC2 or VPCs. Load balancing evenly distributes load to application instances in all availability zones in a region while auto scaling makes sure instances scale up or down depending on the load.
Why Load Balance and Auto Scale at the Same Time?
Paired together, auto scaling and load balancing provide useful benefits. Say you want to smoothly handle traffic surges to your website. When load increases, you want the website infrastructure to have enough capacity to serve the traffic. During bouts of low activity, naturally you want to reduce capacity.
With load balancing alone, you’ll have to know ahead of time how much capacity you need so you can keep additional instances running and registered with the load balancer to serve higher loads. Or you could manually stop worrying about it and auto scale based on say CPU usage so that instances increase or decrease dynamically based on the load. Now this should give you a good idea of why it makes sense to have both.
