With cloud computing has attracted a lot of industries for reducing the efforts on maintaining devices, more and more appliances and telecoms try to develop their own cloud platforms to sell the resources as cloud services for individuals and industries. In order to support operation of cloud service platform, it is necessary to build up the billing management functions which aim at charging to the customers using cloud service. In this billing sub-system of Cloud Business Operation Supporting System (Cloud BOSS) which supports the operation and management of Compute as a Service (CaaS) such as virtual machine and storages services in Chunghwa Telecom (CHT), it realizes the concept of pay by usage such as net flow and storage space usages from customers. In the billing sub-system, it includes service usage collection, rating, invoicing management functions. Moreover, we introduce an auditing function which is responsible for monitoring the charging process to avoid the interruptions or incorrectness. In chapter 1, we have a brief introduction about the cloud computing service features. In chapter 2, we describe the development strategies and goals on what we develop the billing sub-system. In chapter 3, we discuss the functions and architecture of the billing sub-system. And chapter 4, we introduce the features of the monitor and auditing functions in billing sub-system. In chapter 5, we describe how we enhance the performance of the billing sub-system. Finally, we conclude the discussion and future works on the billing system.
