Assuming that this works as intended, it looks like great project.
Pricing looks reasonable and is considerably cheaper than other options like AWS. The cost will depend on how many processors, memory and storage you use, like with other services.
I also like that they use a "reverse auction" model, which seeks to drive down the price, instead of up.
The hard part obviously will be managing users and providers on the backend. It remains to be seen if they can do that consistently, but their current offering makes a lot of sense. Show Less
