SAP-C02 Design for New Solutions Practice Question
A gaming company is designing a new real-time multiplayer game backend on AWS. The game requires low-latency communication between players (< 50 ms) and the ability to handle up to 100,000 concurrent players. The backend must manage game state, player matchmaking, and chat. The company wants to use managed AWS services to reduce operational overhead. Which solution should a Solutions Architect recommend?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Amazon GameLift for session-based game server hosting, with its built-in matchmaking and fleet management.
Amazon GameLift is purpose-built for session-based multiplayer game hosting, providing integrated matchmaking, fleet management, and auto-scaling to handle up to 100,000 concurrent players with low latency. Option A is incorrect because although DynamoDB can store game state, AWS Lambda is not ideal for real-time game logic due to cold start latency and limited execution duration, and API Gateway adds latency overhead, making it unsuitable for sub-50 ms requirements. Option C is incorrect because deploying game servers on EC2 instances requires manual management of scaling, patching, and fleet health, increasing operational overhead, and while ElastiCache Redis can handle game state and SQS can handle chat, the overall solution lacks a managed game server hosting service. Option D is incorrect because Amazon ECS with Fargate abstracts infrastructure management but does not provide built-in session management, matchmaking, or low-latency optimization for gaming workloads, and containers may introduce latency overhead.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use Amazon DynamoDB for game state, AWS Lambda for game logic, and API Gateway for client communication.
Why it's wrong here
Lambda is not suitable for stateful game server logic; API Gateway adds latency.
- ✓
Use Amazon GameLift for session-based game server hosting, with its built-in matchmaking and fleet management.
Why this is correct
GameLift is purpose-built for multiplayer games, handles scaling, matchmaking, and low-latency.
- ✗
Deploy game servers on EC2 instances behind a Network Load Balancer. Use ElastiCache for Redis for game state and SQS for chat messages.
Why it's wrong here
EC2 instances require manual management of scaling and patching; not optimized for gaming.
- ✗
Use Amazon ECS with Fargate to run game server containers, and use Application Auto Scaling to handle load.
Why it's wrong here
Amazon ECS with Fargate is well-suited for running stateless microservices or API backends, offering excellent scalability and reduced operational overhead for general containerised applications. However, for real-time multiplayer game servers demanding sub-50ms latency and persistent, stateful connections, Fargate's abstraction layer and network model can introduce overhead, making it challenging to consistently meet the strict latency requirements. Game servers often benefit from more direct control over networking and underlying compute resources than Fargate typically provides for such specialised, low-latency workloads.
