AWS SAA-C03 practice-exams-topic-based Auto Scaling question 2

[St73 73]

“An application is hosted in an Auto Scaling group …”

In explanation, ” Otherwise, it is better …” what does it mean “Otherwise”, does it say scaling based on a non utilization metric ?

Hi St73,

Thank you for posting.

The term “Otherwise” refers to situations where the scaling decision is not based on a utilization metric.

• If using a utilization metric (like CPU utilization), Target Tracking Scaling is best because it adjusts automatically to maintain a specific target.

• Otherwise, if the metric doesn’t scale proportionally with the number of instances (like the number of messages in an SQS queue), Step Scaling is better. Step Scaling allows for more precise adjustments based on the size of the metric breach.

So, “Otherwise” means using Step Scaling for non-utilization metrics that need more detailed scaling control.

Hope this clears it up! Let me know if you have any more questions.

Cheers,
