It "scales to zero" as soon as the request stops as far as billing is concerned.
However, the image remains "warm" and incurs zero cost once the last request ends. So I usually have a `/heartbeat` endpoint for this purpose and point a Cloud Scheduler job at it.
I haven't read the docs to figure out the exact heuristics of when it becomes "cold" again.
