Each time you shutdown a backend instance, it will continue to be billed for 15 minutes after. So if your job takes 2 minutes to run on the backend, you will be billed for 17 minutes. B8 instances cost $0.64 for 60 minutes, and your free daily quota is $0.72, so you will only be able to run for 68 minutes before running out of quota, which will happen while the 5th hourly job is being shutdown.
Try using B1 instances, and you'll be fine as long as your job completes in under 7.5 minutes. 7.5 + 15 = 22.5 minutes billed per job 22.5 * 24 / 60 = 9 hours billed per day 9 * 0.08 = $0.72 billed per day which is your free quota -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
