Scale In

This option disables scale-downs for the target tracking policy, while keeping the scale-ups. This means that ASG will not scale down unless you explicitly set up a separate step policy to scale it down.

This is useful when you have special requirements, such as gradual or delayed scale-down.

This policy will not scale down. Make sure you have another policy (either TT or Step) that will scale down this ASG.
This policy will scale both up and down. Make sure you don't have other scaling policies, as they will likely interfere with each other.
