There is a clear distinction between edge and a region. That distinction is defined by the distance and by relation latency. Edge locations are not heavy regions or data centres, per my understanding and hence limited by compute/storage capability. They are also high in number. Cloudflare has 100 odd edge locations all around the world.
Cloudflare and Akamai both have the concept of edge workers - light weight application APIs that can serve modest capacity. Cloudflare also has a cache on the edge.

- firebirdn99 3y agoThey're all data centers in essence; some are way smaller, less functional and some way bigger. But still much smaller than regional DC's (the cloud). Akamai has smaller ones, and hence 1000's of them. While Cloudflare and Fastly have larger PoP(Points of Presence) and a few 100's of them.
- tptacek 3y agoI think this is a network architecture detail, and is using the term "edge" in a subtly different sense than the article is. We have "edge" hosts and "worker" hosts where I work, but "edge" means "the edge of our network, where requests from the Internet land", not "deployed as close as possible to users".
