AWS vis a vis Azure Marketshare

Really interesting analysis on Azure and AWS footprint sizes in Forbes. Spoiler alert, AWS is still leaving Bigfoot puddles as it walks through the competition. The call out items, to me, are (1) it's a zero profit platform for anyone building for the cloud; (2) Microsoft is still tethered to it's own, proprietary, infrastructure;  (3) despite AWS's prowess, Azure is gaining a lot of clients. My read is that a lot of the direction for cloud technology will be centered on the desktop and mobile. We are moving from just the transition of back office functions (databases, SaaS, etc.), into the client. It sounds like a non sequitur, but an enterprise that manages desktops with group polices, et al., needs Active Directory.
