2908 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.

6 questions in Spot & Interruptible Capacity.

  1. Spot & Interruptible Capacity intermediate

    A 300-node interruptible fleet runs stateless batch workers from a 4 GB container image. Reclamation replaces roughly 400 nodes a day and the discount is quoted at 70%. Estimate what the churn costs and at what interruption rate the discount disappears.

  4. Spot & Interruptible Capacity intermediate

    A recommendation platform runs large offline training and feature computation jobs. What must be true architecturally before spot capacity is usable, and what does it cost?

  5. Spot & Interruptible Capacity advanced

    A training pipeline runs on 400 interruptible GPU instances checkpointing every 30 minutes. Regional demand spikes and reclamation goes from a handful of instances an hour to most of the fleet inside ten minutes. What happens minute by minute, and what stops it?
