I agree that this is a big thing to consider here too. I set up a computing cluster in grad school and it was much less costly to make a mistake there than it would have been in a cloud service. Re-running something only wasted wall time and not any money. That said, money is not the only scarce resource here. Researchers can get allocations at university and government HPC systems, but you then have to be quite careful with your allocation of computing time. I remember keeping track of the number of SUs (core-hours) I was burning quite carefully when I used university clusters, since once it is gone, you might not get any more time.
