TLDR
There are 3 possible scaling policies types available in AWS and basic metrics for those policies. Target tracking policy will try to keep the selected metric close to the target value by adding or removing instances. Simple policy and Scaling policy with steps are based on alarms, which you can create on the same page as Target or in Cloud Watch. Even more customized policies can be created using lambdas using Lambda to create custom policies. In such a situation, it would be required to check what is going wrong with the application and use a more sophisticated approach.via the TL;DR App
