I have no idea how much this costs. I have no idea how robust the back end is. I have a million questions about the product already. But, 3tera, you have my attention.
From Larry’s blog:
These services allow one to develop applications without hardware or datacenter cost. They bill for resources used — CPU time, storage, bandwidth. That means there is essentially no cost while an application is being developed and debugged since there is no traffic. When the application goes live, the capacity, and hence cost, grow and shrink dynamically depending upon utilization.
