What is the difference between edge delivery and a CDN?
A classic CDN caches static assets; edge delivery caches and optimizes full dynamic pages and can run logic - bot detection, identity, personalization decisions - at the network edge.
A content delivery network historically cached static files: images, CSS, JavaScript. The HTML of a dynamic storefront passed through uncached, so the slowest part of the page got no benefit.
Edge delivery platforms cache the full rendered page and execute logic at the edge node: assembling dynamic fragments, filtering bots, resolving visitor identity. For a storefront, the page itself is where the latency and the risk live - which is what edge delivery exists to move.
