Amazon SAP-C01 Practice Test - Questions Answers, Page 53

You are the new IT architect in a company that operates a mobile sleep tracking application.

When activated at night, the mobile app is sending collected data points of 1 kilobyte every 5 minutes to your backend. The backend takes care of authenticating the user and writing the data points into an Amazon DynamoDB table. Every morning, you scan the table to extract and aggregate last night's data on a per user basis, and store the results in Amazon S3. Users are notified via Amazon SNS mobile push notifications that new data is available, which is parsed and visualized by the mobile app.

Currently you have around 100k users who are mostly based out of North America.

You have been tasked to optimize the architecture of the backend system to lower cost.

What would you recommend? (Choose two.)

In the current setup, requests go through API Gateway to Lambda and either start a container in Fargate or push a message to an SQS queue. An EC2 Fleet provides EC2 instances that serve as workers for the SQS queue. The EC2 Fleet scales based on the number of items in the SQS queue.
