  With the rapid growth of the cloud computing marketplace, the issue of
pricing resources in the cloud has been the subject of much study in recent
years. In this paper, we identify and study a new issue: how to price resources
in the cloud so that the customer's risk is minimized, while at the same time
ensuring that the provider accrues his fair share. We do this by correlating
the revenue stream of the customer to the prices charged by the provider. We
show that our mechanism is incentive compatible in that it is in the best
interest of the customer to provide his true revenue as a function of the
resources rented. We next add another restriction to the price function, i.e.,
that it be linear. This removes the distortion that creeps in when the customer
has to pay more money for less resources. Our algorithms for both the schemes
mentioned above are efficient.
