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

What genuinely belongs in an edge function, and what is the failure mode of putting too much there?

Which parts of a personalised page would you compute at the edge, and where does each piece of state live?

A VP says the app feels slow in Asia and asks whether the team should move it to the edge. Walk me through how you scope that conversation.

A global platform is deciding what to run at the edge, in a regional cloud, and centrally. What determines the placement of each capability?

An attacker has physical possession of one of your devices. What should they be able to obtain, and what protects the rest of the fleet?

How do you establish that code running on a remote device or accelerator is what you deployed?

A fleet platform adds a persistent reverse tunnel from every one of its 220,000 devices to a support broker, so engineers can open a shell on any unit and avoid a site visit. What does that buy, what does it pay, and when does the bill arrive?

A micromobility operator manages tens of thousands of vehicles in cities. What does the fleet management architecture need beyond tracking?

A vehicle fleet uploads terabytes of sensor data daily over unreliable networks and models must be updated over the air. How should edge filtering, resumable uploads, prioritisation, staged model rollout and on-device rollback be designed?

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?
