Networking and Content Delivery
Amazon CloudFront
Amazon CloudFront delivers content and APIs through a global edge network with caching and edge security integrations. It improves static AI application delivery and can accelerate cacheable or streaming origin traffic.
Key points
- Cache behavior keys control which headers, cookies, and queries vary an object
- Origin access control protects supported S3 origins
- WAF and edge functions can filter requests before origin processing
When to use it
- Deliver a global chat web application and static assets
- Cache public, deterministic model-generated reference content
Exam tips
- Use CloudFront for edge delivery, not for caching personalized answers without correct identity and freshness keys
- Streaming can improve perceived latency, but origin timeout and partial-response handling still matter
