Which utility meets the NIST requirement of Metered Service when building a private cloud?

The concept of Metered Service in the context of NIST (National Institute of Standards and Technology) guidelines for cloud computing refers to a way of providing resources that allows for consumption-based billing. This essentially means that users are charged based on the amount of resources they actually use, rather than a flat fee.

The Chargeback utility aligns perfectly with this requirement, as it concerns the ability to track resource consumption and associate it with corresponding costs. By implementing a chargeback system, organizations can monitor which resources are being utilized by different departments or users, thereby facilitating accurate billing based on actual usage. This effectively promotes accountability and can help in managing and optimizing resource usage in a private cloud environment.

Other options, while related to cloud management, do not inherently offer the metering capabilities necessary to fulfill the NIST standard for metered service. Resource Allocation refers to the distribution of resources without addressing the billing aspect; Load Balancing deals with distributing workloads across resources to optimize performance, and Service Level Agreements define the expected performance criteria without incorporating billing based on usage. Thus, Chargeback stands out as the solution that directly supports the NIST requirement for metered services in a private cloud.
