Simple meaning

Model serving is the production system that loads a registered model and answers prediction requests.

WHY — Model Serving instead of guessing?

Why interviewers care about Model Serving:

Model Serving questions separate

people who only read docs from people who shipped.

Keep it short, concrete,

and tied to MLOps work.

Stay structured

Close cleanly

End with when you use it and one common pitfall.
