The business advantage of edge computing is partly latency performance and partly bandwidth efficiency, the same rationale that drove content delivery networks to edge computing (storage, primarily).
Video consumption patterns typically have 80 percent of customers consuming 20 percent or less of the available content on a streaming platform, for example.
By edge caching 20 percent of the catalog, content providers have 80 percent of traffic being pulled from edge data centers, and not across the wide area network backbone.
That improves user experience, but also means less spending on WAN facilities.
The theory is that applications and use cases that require lots of processing--including those apps requiring use of artificial intelligence--can do much of the heavy lifting locally. The same goes for use cases involving process control, which needs to happen in real time, or nearly in real time.
