You must be talking about renting resources that run 100% of the time. AWS rents us gpu instances by the second. We have to run sporadic jobs throughout the day

You must be talking about renting resources that run 100% of the time. AWS rents us gpu instances by the second. We have to run sporadic jobs throughout the day that take 50 seconds to two hours. Depending on customer activity we might need to run 10 or more at once, or we might lie idle for an hour. The elastic economics are unbeatable.
