Answer: Amazon CloudFront

## Explanation Amazon CloudFront is AWS's content delivery network (CDN) service that uses AWS edge locations to cache and deliver content closer to end users for improved performance and lower latency. **Why the other options are incorrect:** - **A. Amazon Virtual Private Cloud (Amazon VPC)**: This is a networking service that allows you to create isolated virtual networks within AWS, but it doesn't use edge locations. - **C. Amazon Elastic Compute Cloud (Amazon EC2)**: This is a compute service that provides virtual servers, but it operates from AWS regions, not edge locations. **Key Points:** - AWS edge locations are part of the AWS Global Infrastructure - They are used primarily by services that require content delivery and caching - CloudFront uses edge locations to cache content globally - Edge locations help reduce latency for end users by serving content from locations closer to them
