Primetime

Hello,

maybe it is a "stupid" question, but google cant answer me:

Adobe Media Server is a "part" of Adobe Primetime?

if NO:

What is the difference between AMS and Primetime?

How Adobe Primetime works? ! !

What is the steaming technology in Primetime?

It works in Adobe's cloud only or can I install some Primetime Server component to my server?

Thank you.
