Zoom includes network, compute, video, voice, recording, recording-storage, transcription, mobile clients, telecom/phone-in, meeting controls, webinar controls, in app messaging, presumably global data centers, calendars, whiteboards, 3rd party app integrations for calendars and schedule, zoom-rooms/hardware, "zoom apps" - 3rd party application integration, bot integration, and a whole enterprise VOIP business on top of it all.
It's a good question, honestly. My go-to answer is just "scale" -- the number of people required to go from "1,000 video calls that are pretty good" to "1,000,000 video calls that are close to perfect" is probably insane, for a lot of reasons that I won't even speculate on.
in an engineering org what’s the ratio of engineers (hands on keyboard) to non engineers? 50-50?
8 hours a day 5 days a week 20 days a month what are 2000 engineers working on related to zoom?
