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?
