An internal browser-based application operates on EC2 instances with an Application Load Balancer, within an Auto Scaling group spanning multiple AZs. It scales to 20 instances during work hours and down to 2 overnight, causing slow performance at day start. How to optimize scaling for performance and cost?
A
Set a scheduled action to increase desired capacity to 20 before work hours.
B
Use a step scaling action with a lower CPU threshold and reduce the cooldown period.
C
Deploy a target tracking action with a lower CPU threshold and shorten the cooldown period.
D
Establish a scheduled action to set both min and max capacity to 20 before work hours.
