Cost Utility Research Of Cloud Computing

Cloud Computing is a new popular IT concept. Different from many former popular concept, such as cluster, utility computing, grid computing, SaaS etc, cloud computing is not a new technology invented by some enterprise or institute. Cloud computing instance is earlier than the concept of the phrase. It at first appeared in some internet company's successful business mode. They depend on different technology but have similar attribute-deliver a mass of cheap services through internet. Finally they are gathered together and raised as a new concept. In other word, although cloud computing is architected on SaaS, virtualization and distributed storage technologies, it is always not a simple technical concept. It's success is now mainly depended on it profitable business mode, contrasting the not so success of grid computing. This is the reason why to choice cloud computing cost analyzing as the research direction in this paper.Cloud computing is variable. Different vender has different technical architecture and usage mode. This made cloud computing looks confusing. In fact, it is still not well defined now. In order to make clear the concept and mode of cloud computing. This paper at first analyzed some representative cloud computing instance, and classified it. And then analyzed the overall character of different cloud computing mode, include bandwidth, computing resources, and low cost, and the support technology, virtualization. All these overall characters will based on the cost. Then analyzed the cost constitutes of different type of cloud computing. The cost constitutes is different from company and type, this paper will focus on IaaS based cloud computing, because IaaS is more standardize than other type, and it is more significant to research.Cloud computing is success because users prefer it. This paper analyzed the basic drive that push user from traditional data center to cloud computing-include the cost comparison between traditional data center to cloud computing, and the advantages of elasticity cost of cloud computing. Then transfer view to cloud computing operator, analyzed how could the cost attract potential users. Through the approach, this paper analyzed the cost constitutes of cloud computing, and focus on the hardware TCO. In order to measure different resources, this paper gave out the concept of standardization of computing resource. This paper also gave out cost formula after analyzed the cloud cost. Cloud operator and engineers cared the cloud utility most, based on the resource standardization and cost formula, this paper present the cost utility function. Based on the cost formula and cost utility function, this paper give out the maximized cost utility solution of computing resource. The last, this paper analyzed the technical methods to improve cost utility. Through ACPI, IPMI, and virtualization, computing resources could be refined managed. Refined-management and auto-workload server will reduce cloud cost and improve cost utility.
