Exam AWS Certified SysOps Administrator - Associate topic 1 question 112 discussion

A company has an application that runs on a fleet of Amazon EC2 instances behind an Elastic Load Balancer. The instances run in an Auto Scaling group. The application's performance remains consistent throughout most of each day. However, an increase in user traffic slows the performance during the same 4-hour period of time each day.
What is the MOST operationally efficient solution that will resolve this issue?

  • A. Configure a second Elastic Load Balancer in front of the Auto Scaling group with a weighted routing policy.
  • B. Configure the fleet of EC2 instances to run on larger instance types to support the increase in user traffic.
  • C. Create a scheduled scaling action to scale out the number of EC2 instances shortly before the increase in user traffic occurs.
  • D. Manually add a few more EC2 instances to the Auto Scaling group to support the increase in user traffic.

I'm voting for C! They see the same slow performance at the same time each day. Scheduled scaling makes sense. Scheduled scaling helps you to set up your own scaling schedule according to predictable load changes. For example, let's say that 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 configure a schedule for Amazon EC2 Auto Scaling to increase capacity on Wednesday and decrease capacity on Friday. To use scheduled scaling, you create scheduled actions. Scheduled actions are performed automatically as a function of date and time. When you create a scheduled action, you specify when the scaling activity should occur and the new desired, minimum, and maximum sizes for the scaling action. You can create scheduled actions that scale one time only or that scale on a recurring schedule. https://docs.aws.amazon.com/autoscaling/ec2/userguide/ec2-auto-scaling-scheduled-scaling.html
