Enterprise Management Association analyst Torsten Volk argues that at a minimum providing a show back mechanism is crucial for any fledgling private cloud.  "If you can't at least show who is responsible for the cycles that have been used, then there is no incentive to use those resources efficiently," Volk says.

JC Martin, cloud architect at eBay, which is now running a second-generation private cloud based on OpenStack technology, explains that eBay's homegrown chargeback program works more like a pre-paid plan where departments pay up front annually for their anticipated IT service costs. He contends the system also helps cut down on having machines sit idle due to departments holding onto virtual machines when they are not using them. "Having to view reports that hold you accountable is a big incentive not to commandeer machines you can't keep busy," Martin says.
