AWS Certified Solutions Architect – Associate (SAA-C03)Design High-Performing ArchitecturesMedium
A global gaming company is developing a new multiplayer online game. The game server architecture is distributed across multiple AWS regions to reduce latency for players worldwide. They need a networking solution that can direct players to the closest game server endpoint and quickly reroute traffic in case of a regional server failure, ensuring a seamless gaming experience. Which AWS service is most suitable for this requirement?
- AAWS Global Accelerator.
- BAmazon Route 53 with a simple routing policy.
- CAn Application Load Balancer (ALB) in each region.
- DAWS Transit Gateway.
Show answer & explanationAnswer & explanation
Correct answer: A. AWS Global Accelerator.
AWS Global Accelerator uses the AWS global network backbone and intelligent routing to direct user traffic to the nearest healthy endpoint, significantly reducing latency for global players and providing fast failover in case of regional outages. This ensures a seamless gaming experience by always connecting players to the best available server.
Why the other options are wrong
- B. Route 53 simple routing does not consider user location or endpoint health for optimal routing; latency-based routing is better but Global Accelerator offers more significant performance and failover benefits.
- C. ALBs operate within a single region (or across AZs) and cannot direct traffic across multiple regions to the closest endpoint or handle global failover directly.
- D. AWS Transit Gateway is for connecting VPCs and on-premises networks; it does not optimize player-to-game-server routing based on latency or provide global failover capabilities for users.
AWS Global Accelerator
AWS Global Accelerator improves the availability and performance of applications by directing user traffic to the nearest healthy endpoint across multiple AWS regions using the AWS global network backbone.
- Uses static IP addresses as entry points.
- Routes traffic over AWS global network, bypassing congested public internet.
- Improves performance and availability.
- Supports multi-region active-active or active-passive architectures.
- Directs users to the optimal endpoint based on health and geographic location.
Memory trick: Global Accelerator is the express lane for gamers, always taking them to the best server.
