It claims each server serves up to 10,000 streams simultaneously. So operational peak capacity is at ~50M simultaneous streams.
Also, 10k streams at 1080p would be ~70Gbps per machine at full HD, or ~20Gbps per machine at SD. With some blend of course being the norm.
There is of course a big difference between being capable of and actual and FUD.
I'd really love to know what the internals of one of their streaming servers might look like.
Anyone here who has architected a box with that capacity?
