I have a question on the basic viability of using the cloud for research.
If I purchase six computers to do my data analysis: I own them and I can use them until the smoke comes out of them in a few years. When I have a new idea for a computation: No problem, I just do it, many times over as needed.
In contrast my cloud use has a calculated budget that corresponds to how many calculations I can do. So how do I “plan” to use the cloud to come in on budget when – by the nature of research – there is always going to be a new idea for a new calculation? I just don’t see the value-for-cost of renting VMs; how do cloud users deal with this?
