2707 questions of the kind that actually get asked — in interviews, in architecture review boards, and by the person who has to run the thing at 3 AM. Every answer states the trade-off rather than the slogan, and says when the obvious choice is the wrong one.

Quiz

A million devices report telemetry every ten seconds. How should ingest, buffering, backpressure and storage be designed, and where do naive designs fail?

After a five-minute network outage at your ingest tier, 200,000 devices reconnect simultaneously and the authentication service collapses. How do you fix this?

Design ingestion for millions of devices sending telemetry continuously over unreliable networks.

Two million devices reconnect simultaneously after a network partition. What happens and what prevents it?

WeChat's DAGOR overload control (SoCC 2018) sheds load using the time requests spend queued inside a service rather than response time, and drops by business and user priority. How would you apply that to a device-fleet ingest tier, and what must the device do for it to work?
