Your company currently has the following architecture for its e-commerce application.
· EC2 Instances hosting the application
· An Autoscaling group for the EC2 Instances
The users who use the application keep on complaining that the application is slow in the morning from 9:00 – 9:30, after which no issues occur. Which of the following can be done to ensure the issue is not encountered during the morning time?

Answer options:

A.Ensure that a Simple scaling policy is added to the Auto scaling Group.
B.Ensure that a step scaling policy is added to the Auto scaling Group.
C.Ensure that a scheduled scaling policy is added to the Auto scaling Group.
D.Ensure that a static scaling policy is added to the Auto scaling Group.

Answer – C
The AWS Documentation mentions the following.
Scaling based on a schedule allows you to scale your application in response to predictable load changes. For example, every week, the traffic to your web application starts to increase on Wednesday, remains high on Thursday, and starts to decrease on Friday. You can plan your scaling activities based on the predictable traffic patterns of your web application.
Option A is incorrect because simple scaling increases or decreases the group`s current capacity based on a single scaling adjustment.
Option B is incorrect because Step Scaling increases or decreases the group`s current capacity based on a set of scaling adjustments, known as step adjustments, that vary based on the size of the alarm breach.
Option D is incorrect since Static scaling policy doesn’t exist.
