Exam AWS Certified Database - Specialty topic 1 question 358 discussion

A company's application team needs to select an AWS managed database service to store application and user data. The application team is familiar with MySQL but is open to new solutions. The application and user data is stored in 10 tables and is de-normalized. The application will access this data through an API layer using a unique ID in each table. The company expects the traffic to be light at first, but the traffic will increase to thousands of transactions each second within the first year. The database service must support active reads and writes in multiple AWS Regions at the same time. Query response times need to be less than 100 ms.

Which AWS database solution will meet these requirements?
