Starting today in preview, Amazon DynamoDB global tables now supports multi-Region strong consistency. DynamoDB global tables is a fully managed, serverless, multi-Region, and multi-active database used by tens of thousands of customers. With this new capability, you can now build highly available multi-Region applications with a Recovery Point Objective (RPO) of zero, achieving the highest level of resilience.
Multi-Region strong consistency ensures your applications can always read the latest version of data from any Region in a global table, removing the undifferentiated heavy lifting of managing consistency across multiple Regions. It is useful for building global applications with strict consistency requirements, such as user profile management, inventory tracking, and financial transaction processing.

DynamoDB global tables with multi-Region strong consistency is billed according to existing global tables pricing.
