A user is planning to scale up an application by 8 AM and scale down by 7 PM daily using Auto Scaling. What should the user do in this case?

A. Setup the scaling policy to scale up and down based on the CloudWatch alarms

B. The user should

increase the desired capacity at 8 AM and decrease it by 7 PM manually

C. The user should setup a batch process which launches the EC2 instance at a specific time

D. Setup scheduled actions to scale up or down at a specific time

Explanation:

Auto Scaling based on a schedule allows the user to scale the application in response to predictable load changes. To configure the Auto Scaling group to scale based on a schedule, the user needs to create scheduled actions. A scheduled action

tells Auto Scaling to perform a scaling action at a certain time in the future.
