You can check whether the prediction based on a predictive scaling rule meets your expectations so that you can determine whether to make corresponding adjustments. For example, if the predictive mode of a predictive scaling rule is set to Predict Only and the prediction meets your expectations, you can set the predictive mode to Predict and Scale. This way, Auto Scaling can automatically adjust the minimum and maximum numbers of instances.
Procedure
What to do next
If the predictive mode is set to Predict and Scale, Auto Scaling automatically creates scheduled tasks for the predictive scaling rule
based on the scheduled plans generated from the prediction. You can view the details
of the scheduled tasks on the Scheduled Tasks page. These tasks are named in the following format: PredictiveScaling-Scaling rule
name-Execution time. 

After the scheduled tasks are executed, the minimum and maximum numbers of instances
in the scaling group are modified, and the system automatically deletes scheduled
tasks that are successfully executed. You can view the details of the scaling activities
triggered by these scheduled tasks on the Scaling Activities tab.
