What it shows

  • Route 53 latency routing serves users from the closest regional edge.
  • DynamoDB Global Tables handle bidirectional replication in under 1 second.
  • Last-writer-wins conflict resolution requires idempotent write payloads.

The takeaway

Active-active delivers sub-second failover and local reads, but requires conflict-tolerant data design.
