AWS adds lightweight JavaScript at CloudFront’s edge

CloudFront Functions gives streaming teams a way to make small content-delivery changes at the CDN edge without moving those decisions back to origin infrastructure. Because AWS frames it around high-scale, latency-sensitive CDN customizations, the feature is aimed at workflows where every millisecond matters. In the broader streaming stack, that puts more logic directly into CloudFront rather than separate application layers. The main signal to watch is how AWS describes supported JavaScript behavior and any limits it places on function size or execution scope.
