Just to chime in for anyone confused by the huge price difference.

In my experience, App Engine Standard Environment with automatic scaling will effectively scale down to "0 instances": After 15 minutes with no request, with automatic scaling, you are billed NOTHING.

Google states on their pricing page:

Accrual of instance hours begins when an instance starts and ends as described below, depending on the type of scaling you specify for the instance:

  • Basic or automatic scaling: accrual ends fifteen minutes after an instance finishes processing its last request.
  • Manual scaling: accrual ends fifteen minutes after an instance shuts down.
