AWS Certified Solutions Architect - Associate SAA-C03 — Topic 1 Question 303

Question

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?

Accepted Answer

Correct answer: D. The correct answer is D. Option D: Use AWS Application Auto Scaling with target tracking policies to scale when ECS metric breaches trigger an Amazon CloudWatch alarm. Auto Scaling adjusts capacity automatically to match demand, improving availability and cost efficiency. Amazon ECS orchestrates containers and integrates natively with AWS networking and IAM. Amazon CloudWatch collects metrics, logs and alarms to monitor and react to operational health. This option delivers the requirement at the lowest cost.
