Roles
Permissions :dfn:`Roles` define the operations a user is allowed to perform, and are currently an ordered list of permission levels.
+ Server Capability
+ Server Capabilities
+ A :dfn:`Server Capability` (not to be confused with a "Capability") expresses the capacity of a :term:`cache server` to serve a particular kind of traffic. For example, a :dfn:`Server Capability` could be created named "500GB" to be assigned to :term:`cache servers` with at least 500 GigaBytes of cache storage space. :dfn:`Server Capabilities` can also be required by :term:`Delivery Services`, which will prevent :term:`cache servers` without that :dfn:`Server Capability` from being assigned to them. It also prevents :term:`Mid-tier Cache Servers` without said :term:`Server Capability` from being selected to serve upstream requests from those :term:`Edge-tier Cache Servers` assigned to the requiring :term:`Delivery Services`.
Review comment:
Well maybe I should choose a different example. A cache server that has RAM disk caches has the capacity to serve traffic that that rapidly requests newly-generated content.
