A company has a three-tier application for image sharing. The application uses an Amazon EC2 instance for the front-end layer, another EC2 instance for the application layer, and a third EC2 instance for a MySQL database. A solutions architect must design a scalable and highly available solution that requires the least amount of change to the application. Which solution meets these requirements?

When we are talking about sharing static content and options have S3 why would I select any other option.

A: Requires changing EC2 application to Lambda. Seems like a big change B: RDS DB is not best option for serve images and also single instance isn't HA C: Memory optimised instance is not HA D: Multi-AZ EBS is lift and shift for EC2 front-end and app later. RDS Multi AZ is HA. S3 for static images is best performance/scalability/availability.
