Which solution meets these requirements?
Configure an accelerator in AWS Global Accelerator. Add a listener for the port that the application listens on, and attach it to a Regional endpoint in each Region. Add the ALB as the endpoint.
Create an Amazon CloudFront distribution and specify the ALB as the origin server. Configure the cache behavior to use origin cache headers. Use AWS Lambda functions to optimize the traffic.
Create an Amazon CloudFront distribution and specify Amazon S3 as the origin server. Configure the cache behavior to use origin cache headers. Use AWS Lambda functions to optimize the traffic.
Configure an Amazon DynamoDB database to serve as the data store for the application. Create a DynamoDB Accelerator (DAX) cluster to act as the in-memory cache for DynamoDB hosting the application data.
Explanations:
AWS Global Accelerator improves application availability and performance by directing traffic to healthy endpoints in different Regions. By adding a listener and specifying the ALB as the endpoint, it can effectively monitor health and reduce latency for users across various locations.
While Amazon CloudFront can help with caching and reducing latency by serving content closer to users, using the ALB as the origin server does not inherently provide health checks or traffic redirection to healthy endpoints. The configuration described does not address the need for monitoring application health directly.
This option incorrectly specifies Amazon S3 as the origin server, which is not suitable for a gaming application requiring low latency and health monitoring. Additionally, using Lambda functions for traffic optimization does not address the specific need for health checks and traffic redirection based on application health.
Amazon DynamoDB and DAX are focused on data storage and caching, not on monitoring the health of the application or directing traffic to healthy endpoints. This option does not address the latency and traffic redirection requirements of the gaming application.
I appraise that the answer is:
Configure an accelerator in AWS Global Accelerator. Add a listener for the port that the application listens on, and attach it to a Regional endpoint in each Region. Add the ALB as the endpoint.
