It can happen on an edge API system servicing customer devices, between the edge and mid-tier services, or from mid-tiers to data stores. It provides a good read on the availability and latency ranges under different production conditions. Also, since this logic resides on the server side, we can iterate on any required changes faster.

A lot of people surmise that TTFB is merely time spent on the server, but that is only a small fraction of the true extent of things. The first—and often most surprising for people to learn—thing that I want to draw your attention to is that TTFB counts one whole round trip of latency. But what else is TTFB? Expect closer to 75ms.

If servers reach maximum load and capacity in-house, something has to give before adding new services.
