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
service over the Internet which requires whitelisting of all public IP addresses used to communicate with it. A
maximum of 4 whitelisting IP addresses are allowed at a time and can be added through an API.

A customer has a 10 GB AWS Direct Connect connection to an AWS region where they have a web application
hosted on Amazon Elastic Computer Cloud (EC2). The application has dependencies on an on-premises
mainframe database that uses a BASE (Basic Available. Sort stale Eventual consistency) rather than an ACID
(Atomicity. Consistency isolation. Durability) consistency model. The application is exhibiting undesirable
behavior because the database is not able to handle the volume of writes. How can you reduce the load on your
on-premises database resources in the most cost- effective way?
