DynamoDB

DynamoDB is a non-relational database. It is a fully managed service created by AWS. With DynamoDB you create tables, but unlike a relational database, each table is completely independent.

DynamoDB is not like the server-based services that AWS offers (RDS, ElastiCache, etc.), it is "serverless" in the sense that you do not have any control over the physical infrastructure that it runs on. You do not pay for the service when you are not using it (except used storage space). Because DynamoDB is different than server-based offerings, the mechanisms for redundancy are also different. DynamoDB offers multi-region, active/active service if you elect it. This is called DyanmoDB Global Tables.

Create a DynamoDB table and extend it as a Global table into a second region.
