Amazon DynamoDB global tables now support replication across AWS accounts

This article announces multi-account global tables for Amazon DynamoDB, enabling data replication across multiple AWS accounts and Regions.

• Replicate DynamoDB tables across multiple AWS accounts and Regions for enhanced isolation
• Two global table models: same-account and multi-account, each for different architectural patterns
• Multi-account tables support fast local writes, asynchronous replication, and last-writer-wins conflict resolution
• Enhanced disaster recovery with account-level isolation to limit impact of security incidents
• Supports organizational compliance and cost attribution across separate business units
• Uses resource-based policies to control which accounts can join replication groups
• Each replica must reside in separate AWS account and separate Region
• Publishes ReplicationLatency metric to CloudWatch for monitoring replication speed
• Configuration changes propagate automatically across Regions when settings replication enabled

Multi-account global tables strengthen DynamoDB's disaster recovery capabilities and compliance support for enterprises managing distributed infrastructure across multiple AWS accounts.
