Question

A SysOps administrator is investigating a company's web application for performance problems. The application runs on Amazon EC2 instances that are in an Auto Scaling group. The application receives large traffic increases at random times throughout the day. During periods of rapid traffic increases, the Auto Scaling group is not adding capacity fast enough. As a result, users are experiencing poor performance. The company wants to minimize costs without adversely affecting the user experience when web traffic surges quickly. The company needs a solution that adds more capacity to the Auto Scaling group for larger traffic increases than for smaller traffic increases. How should the SysOps administrator configure the Auto Scaling group to meet these requirements?
