A company is developing a new online gaming application. The application will run on Amazon EC2 instances in multiple AWS Regions and will have a…

The goal is to optimize network latency for a global online gaming application.

AWS Global Accelerator is the ideal service for this use case. It uses the highly available and congestion-free AWS global network to direct user traffic to the optimal application endpoint (in this case, the regional EC2 fleets). By routing traffic over the AWS backbone instead of the public internet, it significantly reduces latency and jitter, which are critical for real-time gaming.

Amazon CloudFront, a content delivery network (CDN), complements this by caching static assets (like game textures, maps, and installers) and dynamic content (like leaderboards or API responses) at edge locations close to users. This offloads the origin servers and drastically reduces latency for fetching game-related content, improving the overall user experience.

C. AWS Client VPN is designed for secure remote access to a network, not for performance optimization. It introduces encryption overhead, which typically increases, rather than decreases, network latency.

D. An Amazon Route 53 weighted routing policy distributes traffic based on predefined weights, which is useful for load balancing or A/B testing, not for routing users to the lowest-latency endpoint.

E. Requiring users to manually select a region is not an optimal solution for latency. It provides a poor user experience and does not guarantee the user will choose the best-performing network path.
