How to use Amazon DynamoDB global tables to power multiregion architectures

More and more, AWS customers want to make their applications available to globally dispersed users by deploying their application in multiple AWS Regions. These global users expect fast application performance.

In this post, I describe how to use Amazon DynamoDB to power the database of a global backend deployed in multiple AWS Regions. I use DynamoDB global tables, which provide a fully managed, multiregion, and multimaster database so that you can deliver low-latency data access to your users no matter where they are located on the globe.

Why use a multiregion architecture?

AWS customers typically want a multiregion architecture for two reasons:

  1. To provide low latency and improve their app experience.
  2. To facilitate disaster recovery.
