* The `AWS::AutoScalingPlans::ScalingPlan` resource defines an AWS Auto Scaling scaling plan.
*
* A scaling plan is used to scale application resources to size them appropriately to ensure that enough resource is available in the application at peak times and to reduce allocated resource during periods of low utilization. The following resources can be added to a scaling plan:
*
* - Amazon EC2 Auto Scaling groups
* - Amazon EC2 Spot Fleet requests
* - Amazon ECS services
* - Amazon DynamoDB tables and global secondary indexes
* - Amazon Aurora Replicas
*

*
* For predictive scaling to work with a customized load metric specification, AWS Auto Scaling needs access to the `Sum` and `Average` statistics that CloudWatch computes from metric data.
*
* When you choose a load metric, make sure that the required `Sum` and `Average` statistics for your metric are available in CloudWatch and that they provide relevant data for predictive scaling. The `Sum` statistic must represent the total load on the resource, and the `Average` statistic must represent the average load per capacity unit of the resource. For example, there is a metric that counts the number of requests processed by your Auto Scaling group. If the `Sum` statistic represents the total request count processed by the group, then the `Average` statistic for the specified metric must represent the average request count processed by each instance of the group.
*
* If you publish your own metrics, you can aggregate the data points at a given interval and then publish the aggregated data points to CloudWatch. Before AWS Auto Scaling generates the forecast, it sums up all the metric data points that occurred within each hour to match the granularity period that is used in the forecast (60 minutes).
