Amazon debuts CloudFront Functions for running lightweight code at the edge SHARE Amazon Web Services Inc. is beefing up the capabilities of its Amazon CloudFront content delivery network, enabling more lightweight customizations for users at the network edge. Amazon Cloudfront is a fast content delivery network service that’s used by customers to deliver data, videos, applications and application programming interfaces securely to users globally with high transfer speeds and low latency, within a developer-friendly environment. It does this by delivering content from the closest edge location within Amazon’s worldwide network of data centers. When a user requests content that’s being served through CloudFront, the request is routed to whichever edge location provides the lowest latency, so that the content is delivered in the fastest possible time.
