We are in the middle of converting a single enterprise database into a 3 node casual cluster and the current thought is to use an auto scaling group to manage the ec2 instances. After looking around I haven't seen this mentioned before and wondering why (or if I'm blind)? The templates don't use an autoscaling group and this article from a few years ago does mention the possibility of an auto scaling group, but it's referring to a HA cluster so I'm not sure if that's still relevant.
