A web application running on Amazon EC2 instances writes data synchronously to an Amazon DynamoDB table configured for 60 write capacity units. During normal operation the application writes 50 KB/s to the tale, but can scale up to 500 KB/ s during peak hours. The application is currently throttling errors from theDynamoDB table during peak hours.What is the MOST cost-efficient change to support the increased traffic with minimal changes to the application?
