What Does Measured Service in Cloud Computing Mean?
Measured service is a delivery model in which a utility provider monitors how much of a particular service each customer consumes within a designated time period. Measured services give the provider insight into resource consumption and provide customers with transparency into how they are billed for the services they consume.
Measured services are supported by metering capabilities appropriate to the type of service consumption in question. For example, metering for cloud computing resources can be based on how much storage the cloud customer uses, how much processing power they use, how much network bandwidth they consume -- or in the case of SaaS applications, the number of active user accounts.
Measured services are an important characteristic of cloud computing according to the National Institute of Standards and Technology (NIST).
