Is DynamoDB multi-region?

It can be. A standard DynamoDB table lives in one Region, but global tables make it multi-Region and multi-active, replicating automatically across your chosen Regions so you can read and write in any of them. Global tables offer up to 99.999% availability, with eventual or opt-in strong multi-Region consistency.

Standard tables vs global tables

By default a table exists in a single Region. Turn on global tables to add replica tables in other Regions; DynamoDB then keeps them in sync automatically.

Multi-active replication

Every replica accepts both reads and writes. A write to any Region propagates to the others — there is no primary Region and no failover step if one Region becomes unavailable.

Consistency choices

• Multi-Region eventual consistency (MREC) — writes replicate asynchronously, typically within a second. Conflicts resolve last-writer-wins.
• Multi-Region strong consistency (MRSC) — an opt-in mode where a write is synchronously confirmed in another Region before returning.

Why use it

Low-latency local access for globally distributed users, plus resilience and business continuity.
