  Aurora is more complex to set up and manage.... DynamoDB is simpler to use, less configuration needed, the most important is highly scalable, auto-scaling https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/AutoScaling.html

  DynamoDB provides the best read and write capacity here.

• Chose A3

  I also initially thought Aurora is better suited since it gives auto scaling as well as auto scaling. However, it doesn't auto scale for writer instances. there is a note in Aurora doc: "Aurora Auto Scaling doesn't apply to the workload on the writer DB instance. Aurora Auto Scaling helps with the workload only on the reader instances." https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/Aurora.Integrating.AutoScaling.html Hence the right answer is A. But man, how devious! a small detail can derail you from making the right choice!
