Answer: Introduce an accelerator in AWS Global Accelerator with the ALB configured as the origin.
The correct answer is C: 'Introduce an accelerator in AWS Global Accelerator with the ALB configured as the origin.' AWS Global Accelerator helps to improve performance for users globally by optimizing the path to the application's endpoints, which can significantly reduce the latency and variability experienced by users outside the United States. It provides two static IP addresses to act as a fixed entry point to the applications, and it routes traffic through the AWS global network to the optimal regional endpoint, ensuring consistent low latency. This solution also minimizes operational overhead since it doesn't require deploying additional infrastructure across multiple regions.

A SaaS provider uses an Application Load Balancer (ALB) to expose APIs, which include non-standard REST methods such as LINK, UNLINK, LOCK, and UNLOCK, from an Amazon EKS cluster in the us-east-1 region. Users outside the United States are experiencing prolonged and variable response times for these APIs. A solutions architect must address this issue with a solution that minimizes operational overhead. Which of the following solutions is most appropriate?
A
Implement an Amazon CloudFront distribution with the ALB configured as the origin.
B
Set up an Amazon API Gateway edge-optimized API endpoint to expose the APIs, with the ALB as the target.
C
Introduce an accelerator in AWS Global Accelerator with the ALB configured as the origin.
D
Expand the deployment of APIs to additional AWS Regions (eu-west-1 and ap-southeast-2) and utilize latency-based routing records in Amazon Route 53.
