How do resource requests and limits affect model serving?
PICTURE THIS: HOW TO EXPLAIN IT
Simple meaning
Requests help the scheduler place Pods
WHY — Kubernetes instead of guessing?
Why interviewers care about Kubernetes:
question about Kubernetes.
trade-offs, and what you would actually do on a MLOps project - not buzzwords.
Name the idea, why it exists, then one short example.
End with when you use it and one common pitfall.
STEPS — What happens step by step?
Before you speak the answer, walk the interviewer through these steps:
- 1Requests help the scheduler
place Pods
- 2limits cap CPU and
memory so a leak does not starve the node.
- 3If you set CPU
limits too tight, p99 latency spikes under load.
- 4For GPUs you also
request a GPU resource so two models do not collide.
- 5Common mistake
What juniors usually get wrong.
- 6Close
When you pick this over the alternative.

Here's a short line you can speak, broken into clear beats:
Note: Adapt this scaffold to your own project — keep it under 60–90 seconds.
Key takeaway
Requests help the scheduler place Pods limits cap CPU and memory so a leak does not starve the node.
