2827 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.

  1. Edge, Mobile & IoT intermediate Multiple choice

    What do mobile, IoT and edge architectures have in common that data-centre architectures do not?

    2 min answer edgemobileiotconnectivity
  2. Edge Security & Attestation advanced

    A fleet platform decides to require a fresh hardware attestation on every device connection. The gateway issues a nonce, the device returns a boot measurement signed inside its secure element, and only measurements on an allow-list are admitted. The team gets replay resistance and firmware integrity. What have they given up, and when does that bill arrive?

  3. Edge Security & Attestation beginner Multiple choice

    A gateway requires each device to prove it is running approved firmware. The device sends a signed measurement of its boot image, and the gateway verifies the signature against the device's registered key. Why is a valid signature not yet evidence that this device is trustworthy right now?

  4. Edge Security & Attestation advanced

    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?

  5. Edge Security & Attestation advanced

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

  6. Edge Security & Attestation advanced

    In June 2024 Apple described Private Cloud Compute, where a user's device will only send a request to a server node that cryptographically attests to running a specific software image, and the device checks that measurement against a public append-only transparency log before sending anything. What problem does this solve that signed code and audits do not, what does it cost, and where would copying it be a mistake?

  7. Fleet Management advanced

    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?

  8. Fleet Management advanced

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

  9. Fleet Management intermediate

    A platform manages a large number of field devices in varying conditions. What operational capabilities are architectural rather than operational?

  10. Fleet Management advanced

    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?

  11. Fleet Management intermediate

    An IoT platform monitors device telemetry. 800 devices stopped reporting three weeks ago and nobody noticed. Why?

  12. IoT Ingest Architecture advanced

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