A company's new web application running on Amazon EC2 across multiple Availability Zones (AZs) will be heavily accessed during regular business hours. After business hours, usage will be minimal.What fleet-scaling approach should be used to size the EC2 fleet to handle the traffic demands?

• Manual scaling across all AZs

• Provisioning for peak traffic

• Scheduled scaling

• Programmatic termination of all instances in one AZ during off-peak hours

Scaling based on a schedule enables you to scale your application in response to predictable changes in demand. To use scheduled scaling, you create scheduled actions, which tell Spot Fleet to perform scaling activities at specific times. When you create a scheduled action, you specify the Spot Fleet, when the scaling activity should occur, minimum capacity, and maximum capacity. You can create scheduled actions that scale one time only or that scale on a recurring schedule.https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/spot-fleet-scheduled-scaling.html
