Why someone needs API Management in front of CDN like AKAMAI ?

Interested to know what value API Management provides in front of CDN ? What do you think about same ? Or Is it completely not required at all ?

The API Management layer performs certain very important functionalities such as Security (oAuth etc), Traffic Management (spike arrest, quota validation etc). It is important that such important validations are done prior to the response being served back to the client, be it from a CDN.

While there are some obvious overlaps in terms of functionalities between an API Management layer and a CDN such as caching, it is important to not let all requests be served from the cache before the necessary security / quota validations are done.
