Speaking from my experience, it does scale to zero except you pay for 15 mins after the last request.

So if you get all your requests in a 2 hours window then that's great. It will scale to zero for rest of the 22 hours.

However, if you get at least one request every 15 mins then you will pay for 24 hours and it is ~3X more expensive then equivalent VM on Google Cloud.

OK thanks will check out the options again, if it does scale to zero (including CPU) that will make it more reasonably priced.
