Question

A company operates a real-time multiplayer gaming backend across EC2 instances behind Network Load Balancers in three AWS Regions (us-east-1, eu-west-1, ap-southeast-1). Players worldwide report inconsistent connection latency and slow failover when a regional endpoint becomes unhealthy. The backend uses raw TCP and UDP protocols. The company wants players to connect to the nearest healthy Region automatically through static entry-point IP addresses, with fast rerouting during Regional failures. Which solution best meets these requirements?

Accepted Answer

Deploy AWS Global Accelerator with the three regional Network Load Balancers as endpoints, using its two static anycast IP addresses as the client entry points.

Answer

Create an Amazon CloudFront distribution with the Network Load Balancers as custom origins and enable origin failover across the Regions.

Answer

Configure a Route 53 latency-based routing policy with health checks pointing to each Regional Network Load Balancer.

Answer

Set up VPC peering between all three Regions and use a single Application Load Balancer to distribute traffic globally.
