Key points

• CloudFront caches and distributes content from supported origins through edge locations.
• Origin access, cache behavior, viewer authorization, and invalidation determine whether protected data remains controlled.

Best-known use cases

• Cache static reports and exported datasets near geographically distributed consumers.
• Distribute protected S3 content through controlled edge access.

What candidates often confuse it with

• CloudFront accelerates content delivery; API Gateway governs APIs and S3 provides the underlying object storage.
