App Management Service Internals

Is there any documentation published by Microsoft which gives the details about the internal architecture of the app management service?

I have some diagrams which are published here

but this is very very high level and 50K feet overview ... rather than a clear explanation of components (and their responsibilities).

Is there something in depth available?
