A city open-data site serves mostly static PDFs and images from an ALB/EC2 origin, and egress bills keep climbing. Which architecture change best reduces origin and data-transfer cost?
Select an answer to reveal the explanation.
Short Explanation
Put the popular park maps at the edge of town so every visitor doesn't drive downtown. CloudFront caches static assets and trims origin plus egress cost.
Full Explanation
Amazon CloudFront caches static content at edge locations, lowering requests and bytes served from ALB/EC2 origins and typically reducing data-transfer cost for public downloads. Forcing traffic through NAT or VPN increases cost and friction. RDS is not a content-delivery cache for public PDFs.
