Understanding SaaS Architecture Powerpoint Presentation

I've been doing some reading on SaaS today as I'm writing an internal paper about Software as a Services vs. Services that use Software (STUS). I found this presentation on Gianpaolo's site really useful to help me clarify precisely what SaaS is (or at least what Microsoft views it to be) and thought I should share it. 

thanks Gianpaolo and I hope others find it useful! 

if you like this, you'll likely enjoy the blog of his partner in crime, Fred Chong too!
