EDGE computing is the latest buzzword in the IT world, it is commonly used in reference to an evolution of the classic CDN. This evolution adds the ability to make decisions on top of straight content distribution.

Broadly the EDGE is where content storage and decision making is moved closer to the requesting device, rather than relying on a single server location which could be on the other side of the world. This distribution is typically carried out on an Anycast network of servers and has the advantage of reducing latency, saving bandwidth costs, and improving server utilisation. Peakhour is an EDGE provider.
