Mark your calendars: Microsoft is coming to town. Again. On October 20, Microsoft’s cloud crew, including CEO Satya Nadella and its Azure boss, Scott Gutherie, will be in San Francisco to talk about the “cloud” and “Azure.” We don’t have much more than that at the moment, frustratingly. Microsoft is continuing its recent history of coming to the Bay Area, and San Francisco specifically, to pitch its new products and wares.
