Question

A gaming company is launching a new mobile leaderboard service expected to reach 50 million users across North America, Europe, and Asia. Player scores must be readable with single-digit millisecond latency from any region, and score writes made in one region should become visible in other regions within a couple of seconds. The workload is highly spiky, with traffic surging 20x during tournaments. The team wants a fully managed solution that minimizes operational overhead and scales automatically without pre-provisioning capacity for peak. Which design best meets these requirements?

Accepted Answer

Deploy Amazon DynamoDB global tables in the three regions using on-demand capacity mode, with a DynamoDB Accelerator (DAX) cluster fronting reads in each region.

Answer

Deploy Amazon Aurora MySQL with a global database spanning the three regions and use Aurora Auto Scaling to add read replicas during tournaments.

Answer

Run a self-managed Redis cluster on EC2 in each region with cross-region replication and place it behind an Application Load Balancer.

Answer

Deploy Amazon DynamoDB in a single region with provisioned capacity sized for peak, and use Amazon CloudFront with regional edge caches to serve reads globally.
