A model might return its first token quickly but take too long to finish an answer. It might respond promptly and still give the wrong answer. And a busy GPU tells the operations team little about either outcome.
The operational challenge is connecting AI service behavior with the Kubernetes, GPU, compute, storage, and network conditions behind it—not viewing each layer in isolation. That's why you should measure an inference service before production, then compare live behavior with the baseline. Inference adds a further question: Does the whole service deliver a useful result at a cost and speed the business can support? Earlier in this series: - Part 1: Developers and platform teams both want Kubernetes self-service.
