Question

A gaming company runs a serverless leaderboard application backed by an Amazon DynamoDB table in us-east-1. The player base is expanding rapidly in Europe and Asia, and users in those regions report high read and write latency. The company also wants the application to remain fully operational for writes if an entire AWS Region becomes unavailable. Which solution best meets these requirements with the least operational overhead?

Accepted Answer

Configure DynamoDB global tables with replicas in eu-west-1 and ap-southeast-1, and route users to the nearest Regional endpoint.

Answer

Enable DynamoDB Accelerator (DAX) in front of the us-east-1 table to reduce read latency for global users.

Answer

Create on-demand backups of the us-east-1 table and restore them into other Regions during a failure event.

Answer

Add DynamoDB read replicas in eu-west-1 and ap-southeast-1 while keeping all writes directed to us-east-1.
