A user has created a web application with Auto Scaling. The user is regularly monitoring the application and he
observed that the traffic is highest on Thursday and Friday between 8 AM to 6 PM. What is the best solution to
handle scaling in this case?

A.
Add a new instance manually by 8 AM Thursday and terminate the same by 6 PM Friday

B.
Schedule Auto Scaling to scale up by 8 AM Thursday and scale down after 6 PM on Friday

C.
Schedule a policy which may scale up every day at 8 AM and scales down by 6 PM

D.
Configure a batch process to add a instance by 8 AM and remove it by Friday 6 PM

Explanation:
Auto Scaling based on a schedule allows the user to scale the application in response to predictable load
changes. In this case the load increases by Thursday and decreases by Friday. Thus, the user can setup the
scaling activity based on the predictable traffic patterns of the web application using Auto Scaling scale by
Schedule.
