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
