[All AWS Certified Solutions Architect - Associate SAA-C02 Questions]

A company runs a latency-sensitive gaming service in the AWS Cloud. The gaming service runs on a fleet of Amazon EC2 instances behind an Application Load
Balancer (ALB). An Amazon DynamoDB table stores the gaming data. All the infrastructure is in a single AWS Region. The main user base is in that same Region.
A solutions architect needs to update the architecture to support a global expansion of the gaming service. The gaming service must operate with the least possible latency.
Which solution will meet these requirements?

A. Create an Amazon CloudFront distribution in front of the ALB
B. Deploy an Amazon API Gateway regional API endpoint. Integrate the API endpoint with the ALB
C. Create an accelerator in AWS Global Accelerator. Add a listener. Configure the endpoint to point to the ALB.
D. Deploy the ALB and the fleet of EC2 instances to another Region. Use Amazon Route 53 with geolocation routing.

Selected Answer: C

Acceleration for latency-sensitive applications Many applications, especially in areas such as gaming, media, mobile apps, ad-tech, and financials, require very low latency for a great user experience. To improve the user experience, Global Accelerator directs user traffic to the application endpoint that is nearest to the client, which reduces internet latency and jitter. Global Accelerator routes traffic to the closest edge location by using Anycast, and then routes it to the closest regional endpoint over the AWS global network. Global Accelerator quickly reacts to changes in network performance to improve your users’ application performance. https://docs.aws.amazon.com/global-accelerator/latest/dg/introduction-benefits-of-migrating.html
