Feedback on reference architecture / ecosystem

Hi Folks,

I just published a first pass at a reference architecture / ecosystem of cloud services for enterprise application development. Looking for feedback, especially on if there are important categories or services that we've missed. Feel free to discuss here, on the original post, or message me directly ross@box.com. Thanks guys, and hope this is helpful!
