2988 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.

3 questions in Capacity Modelling.

Quiz

A compute platform must plan accelerator capacity where lead times are months, demand is uncertain, and jobs vary from minutes to weeks. How should the capacity model be built?

A game hosts a scheduled in-world event for 30 million concurrent players. How should matchmaking, instance allocation, pre-scaling, login queues and degradation be planned, and what is rehearsed?

A training cluster has 512 NVIDIA H100-class GPUs in 64 eight-GPU nodes and the scheduler reports 96 GPUs free. Roughly how much collective bandwidth per GPU does a new 64-GPU job get, and what should the capacity report say instead of "96 GPUs free"?
