[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A company is launching a new application deployed on an Amazon Elastic Container Service (Amazon ECS) cluster and is using the Fargate launch type for ECS tasks. The company is monitoring CPU and memory usage because it is expecting high traffic to the application upon its launch. However, the company wants to reduce costs when utilization decreases.

What should a solutions architect recommend?

A. Use Amazon EC2 Auto Scaling to scale at certain periods based on previous traffic patterns.
B. Use an AWS Lambda function to scale Amazon ECS based on metric breaches that trigger an Amazon CloudWatch alarm.
C. Use Amazon EC2 Auto Scaling with simple scaling policies to scale when ECS metric breaches trigger an Amazon CloudWatch alarm.
D. Use AWS Application Auto Scaling with target tracking policies to scale when ECS metric breaches trigger an Amazon CloudWatch alarm.

Selected Answer: D

This is running on Fargate, so EC2 scaling (A and C) is out. Lambda (B) is too complex.

Target tracking will scale in/out the ECS cluster to maintain the average CPU utilization to a set value. e.g. <<<50%>>> Scale out when average CPU utilization is above 50% until average CPU utilization is back to 50%. And scale in when average CPU utilization is below 50% until average CPU utilization is back to 50%.
