Demand on an internal app peaks midweek and is low the rest of the week, but the team runs enough servers for the peak every day. What does adding EC2 Auto Scaling change?

Instances launch for the peak and then terminateCorrect · your answerCorrect. New instances are added only when necessary and terminated when they are no longer needed, so the midweek peak costs money while it lasts.

Peak capacity is reserved at a lower rateReserved Instances and Savings Plans lower the rate, but the extra servers still run all week and stay idle on the quiet days.

Traffic is spread evenly across the existing serversLoad balancing shares requests between healthy instances. It answers how work is distributed, not how many servers exist at 3am on Sunday.

Idle servers are billed at a discounted rateNo AWS discount applies to an unused instance. Billing counts the hours an instance runs, whatever its CPU is doing.

Correct.

Concept

Capacity fixed at the peak sits idle most of the time, and capacity fixed at the average breaks under load. Renting by the hour removes that choice.

Why A

Scaling policies add servers as demand climbs and remove them as it falls, so you pay for peak-sized capacity only for the hours the peak actually exists.

You can add new instances to the application only when necessary, and terminate them when they're no longer needed. Because Amazon EC2 Auto Scaling uses EC2 instances, you only have to pay for the instances you use, when you use them…
