Question

A large gaming company is creating a centralized solution to store player session state for multiple online games. The workload required key-value storage with low latency and will be an equal mix of reads and writes. Data should be written into the AWS Region closest to the user across the games' geographically distributed user base. The architecture should minimize the amount of overhead required to manage the replication of data between Regions. Which solution meets these requirements?

Options

  • AAmazon RDS for MySQL with multi-Region read replicas
  • BAmazon Aurora global database
  • CAmazon RDS for Oracle with GoldenGate
  • DAmazon DynamoDB global tables

Explanation

DynamoDB Global Tables is the right fit because it is a fully managed, serverless key-value store that natively supports multi-Region active-active replication - meaning writes can land in any Region and automatically sync globally with no replication infrastructure to manage.

Why the distractors fail:

  • A (RDS for MySQL with read replicas) - read replicas are read-only in remote Regions, so you cannot write closest to the user; this is a read-scaling tool, not a global write solution.
  • B (Aurora global database) - also only supports writes in one primary Region; secondary Regions are read-only, so geographically distributed writes are not possible.
  • C (RDS for Oracle with GoldenGate) - GoldenGate can do multi-master replication, but it is complex to operate, expensive, and adds significant management overhead - the opposite of what the question requires.

Memory tip: Whenever you see the combo of key-value, low latency, global writes, and minimal management, think DynamoDB Global Tables - it is the only AWS-native, fully managed service that checks all four boxes simultaneously. RDS/Aurora options are relational (not key-value) and lack active-active global write capability out of the box.
