You have been asked to leverage Amazon VPC BC2 and SQS to implement an application that submits and receives
millions of messages per second to a message queue. You want to ensure your application has sufficient bandwidth
between your EC2 instances and SQS. Which option will provide the most scalable solution for communicating between
the application and SQS?

A.
Ensure the application instances are properly configured with an Elastic Load Balancer

B.
Ensure the application instances are launched in private subnets with the EBS-optimized option enabled

C.
Ensure the application instances are launched in public subnets with the associate-public-IP address=true option enabled

D.
Launch application instances in private subnets with an Auto Scaling group and Auto Scaling triggers configured to watch the SQS
queue size

Explanation:
Bandwidth literally means network not IO Bandwidth. Having alerts to scale the Auto scaling is most sophisticated option.
