Application Auto Scaling Policy Example

This template creates a scaling policy using the `TargetTrackingScaling` policy type. The policy uses the `CassandraWriteCapacityUtilization` predefined metric. When the metric is at or exceeds 75 percent, the scaling policy increases the capacity of the scalable target, and when it falls below 75 percent, the scaling policy decreases the capacity of the scalable target. The scaling policy has a 60 second cooldown period after every scaling activity.
