Which architecture will meet these requirements with the LOWEST latency for users?
Set up a Multi-AZ environment in a single AWS Region. Use Amazon CloudFront to cache user sessions.
Set up environments in multiple AWS Regions. Create an accelerator in AWS Global Accelerator, and add endpoints from different Regions to it.
Set up environments in multiple AWS Regions. Use Amazon Route 53, and select latency-based routing.
Set up a Multi-AZ environment in a single AWS Region. Use AWS Lambda@Edge to update sessions closer to the users.
Explanations:
While a Multi-AZ environment in a single AWS Region provides high availability and fault tolerance, it does not effectively reduce latency for users located far from that region. Using Amazon CloudFront for caching may help with static content but does not address the low-latency requirement for real-time UDP traffic typical in multiplayer games.
Setting up environments in multiple AWS Regions with AWS Global Accelerator optimizes routing for low latency. It directs user traffic to the nearest endpoint across different regions and uses the AWS global network to improve performance, which is essential for interactive gaming experiences that rely on UDP traffic.
While using Amazon Route 53 with latency-based routing can direct users to the lowest-latency region, it does not inherently provide the same level of optimization and reliability as AWS Global Accelerator for real-time applications. It may not manage UDP traffic effectively and could lead to inconsistent latency.
A Multi-AZ setup in a single region with Lambda@Edge may help with dynamic content updates, but it does not address the requirement for reduced latency for a global user base. Like option A, it lacks the geographic distribution necessary to minimize latency for users far from the primary AWS Region.
From my point of view, the answer is:
Set up environments in multiple AWS Regions. Create an accelerator in AWS Global Accelerator, and add endpoints from different Regions to it.
