Question
A global company wants to run an application in several AWS Regions to support a global user base. The application will need a database that can support a high volume of low-latency reads and writes that is expected to vary over time. The data must be shared across all of the Regions to support dynamic company-wide reports. Which database meets these requirements?
Options
- AUse Amazon Aurora Serverless and configure endpoints in each Region.
- BUse Amazon RDS for MySQL and deploy read replicas in an auto scaling group in each Region.
- CUse Amazon DocumentDB (with MongoDB compatibility) and configure read replicas in an auto
- DUse Amazon DynamoDB global tables and configure DynamoDB auto scaling for the tables.

Explanation
Amazon DynamoDB global tables provide a multi-Region, multi-master database in the AWS Regions you specify. DynamoDB performs all of the necessary tasks to create identical tables in these Regions and propagate ongoing data changes to all of them. DynamoDB auto scaling cost effectively adjusts provisioned throughput to actual traffic patterns.
