I think this is much more useful to a cloud provider than to a customer.
As a customer I think you could configure somethings like you said using spot instances on AWS but that’s it, you’re going to save some small amount of dollars in a year but if you account for the engineering hours needed to set this up maybe is not really worth it.
As a cloud provider you could juggle your client between datacenters depending on the load and price of energy over there. A flat rate for a cloud region means that there’s an opportunity for arbitration between datacenters that could be an increase of thousands in profits on their side.
