Option A, using AWS Global Accelerator, is the correct answer. Global Accelerator provides global static IP addresses that act as a fixed entry point to the application, improving performance by routing traffic to the closest healthy endpoint using the AWS global network. This helps in reducing latency, an important factor for the gaming platform, and ensures that traffic is directed to healthy endpoints, thus enhancing the user experience. Options B and C involve using CloudFront with different origin servers and cache configurations, which are more suitable for content delivery and caching rather than minimizing latency for real-time gaming. Option D focuses on DynamoDB and DAX, which are more relevant for database caching, not for routing traffic based on application health across regions.
