Technical Diagram about security in Powerpivot Architecture and ecosystem

I keep on telling this quite frequently, "A picture is worth thousand words" and the picture that I am going to share is about worth a ten thousand words. SQLCAT team has released a new technical diagram (in fact a poster sized diagram) on powerpivot for excel and sharepoint security architecture. It involves not only security edges of powerpivot, but also all the related components too.

You can download this technical diagram in different formats as listed below.
