A company runs an internal browser-based application The
application runs on Amazon EC2 instances behind an Application Load
Balancer.The instances run in an Amazon EC2 Auto Scaling group across multiple
Availability Zones. The Auto Scaling group scales up to 20 instances
during work hours, but scales down to 2 instances overnight Staff are
complaining that the application is very slow when the day begins,
although it runs well by mid-morning. How should the scaling be changed
to address the staff complaints and keep costs to a minimum?
