CDN Edge Groups

CDN edge groups are groups of edge servers – your own, and those you subscribe to from the CDN marketplace. They are usually grouped by location, so they represent a pool of servers for a given geographical area. Once you have created an edge group containing edge servers in specific locations, you can then assign the group (or groups) to a specific CDN resource.
The CDN edge groups menu enables you to see available edge server locations and form them into CDN Edge groups.
