Explanation
Amazon CloudFront is a Content Delivery Network (CDN) that caches static content (images, videos) at edge locations worldwide, including the US and Europe - meaning users get content from a nearby edge server rather than all the way from Sydney, dramatically reducing latency.
Why the distractors are wrong:
- A (PrivateLink): AWS PrivateLink provides private connectivity between VPCs and AWS services within the AWS network - it does not help with public user latency or content caching.
- B (S3 Transfer Acceleration): Transfer Acceleration speeds up uploads to S3 by routing through CloudFront edge locations - it optimizes data going into S3, not serving content out to end users.
- D (API Gateway per region): API Gateway is for exposing APIs, not for caching or serving static assets; replicating it across regions wouldn't distribute the S3 content itself.
Memory tip: Think of CloudFront as a "global photocopier" - it makes copies of your S3 content at edge locations close to your users. Whenever you see "static content," "S3," and "global users experiencing slow loads," CloudFront is almost always the answer.
