Sharding the data layer past the single-primary ceiling, autoscaling that respects the real bottleneck, backpressure so overload degrades instead of collapsing, and the security and observability that make an asynchronous system operable at all. Closing the backend track.

At hundreds of requests per second a single box is fine. At thousands, caching and replicas earn their keep. At tens of thousands the sync path cracks and state becomes the enemy. At millions, physics starts dictating the architecture. What breaks first at each rung, and the cheapest thing that fixes it.
