While utilizing cloud framework, cloud subscribers don’t need to know the fundamental engineering or the setup abilities. They don’t have to keep up the hardware and framework resources. In any case, they utilize each of those hardware or framework or calculation resources and services. Obviously, these are not free under any condition. Cloud innovation enables the clients to ask for and encourages customers to use just the required amount of resources. Services should be asked for and valued according to the appropriate premise, such as continuously or constantly, which frees up resources when their job is done [6]. Accordingly, clouds should be equipped to permit exchanging services which incorporate accounting, payment and charging services [2]. Metering ought to be classified by the type of required services, for example, processing resources, storage, appliances and framework artifices. Hence, customers need to pay according to the amount of resources and services they utilize, which is the “pay-as-you-utilize” model. In this model, the amount of resources utilized are instantly revealed by metering and charged accordingly.
