Question: Does DynamoDB support Multi-AZ?
Answered by Rafal Wilinski
Answer
Yes, DynamoDB supports Multi-AZ (Availability Zones) deployments. Multi-AZ allows you to create a replica of your DynamoDB table in one or more other Availability Zones (AZs) within the same region. This enables your DynamoDB table to automatically failover to a replica in another AZ if there is an outage or disruption in the primary AZ.
When you create a Multi-AZ table, DynamoDB automatically provisions and maintains a synchronous replica of the table in the other AZ. The replica is updated with every write operation made to the primary table and is used to serve read requests if the primary table becomes unavailable. This feature provides increased availability and data durability for your DynamoDB table.
