In a Zoom call, each user can upload upwards of two streams (one for video, one for screensharing) to a cloud server which then compresses each stream, adjusts the output for the bandwidth and CPU capability of each computer or phone, and sends them back, with as low a latency as possible. Multiply that by up to 100 users, and the problem becomes exponentially more complicated.
