How should they architect their solution?
A web company is looking to implement an external payment service into their highly available application
deployed in a VPC Their application EC2 instances are behind a public lacing ELB Auto scaling is used to add
additional instances as traffic increases under normal load the application runs 2 instances in the Auto Scaling
group but at peak it can scale 3x in size. The application instances need to communicate with the payment
