Streaming's new maths: why owning the pipes beats renting them
As audiences scale, self-hosted delivery and rented cloud bandwidth diverge sharply — and the gap is now a boardroom question.
For years the default answer to "where should our video live?" was the public cloud. It was fast to start, someone else ran it, and the bill felt like a rounding error. At demo scale, it is. At audience scale, it stops being one.
The economics turn on two curves. Storage rises gently with a back catalogue. Bandwidth — the cost of delivering streams to concurrent viewers — rises steeply, and in a rented model every concurrent HD viewer is a metered egress charge that never stops climbing.
Owning the delivery layer flips the shape of that curve. The upfront cost is real, but it is largely fixed: past the crossover point, each additional thousand viewers is close to free. For a publisher planning to grow, that crossover is the whole game.
None of this argues against the cloud for what it is good at. It argues for knowing your numbers — and for treating delivery infrastructure as a strategic asset rather than a utility bill you can never see the bottom of.
