Cost-utility Analysis And Decision-making For Enterprise Cloud Computing Applications

In recent years, as China’s economic reform and more in-depth, the development model of the market economy has become increasingly popular, a principal in a market economy is an indispensable business, but in a market economy is an inevitable phenomenon enterprise there is a fierce competition between, along with increasingly brutal competition among enterprises, companies will need to consider the cost savings of business operation. Due to the rapid development of Internet technology, the rapid growth of information and data, resulting in the ability to store the company’s own data center computing capacity and data can not meet the growing demand. The traditional solution is through the purchase of more advanced equipment to achieve fast computation and high-capacity storage, general business IT hardware needs to be replaced three years a new hardware device, in order to meet the security and enterprise business enterprise information systems business growth needs, but this greatly increases the cost, the cost of enterprise information management in enterprises in the cost will be higher, and how to reduce the cost of information technology companies also need to solve the problems of the modern enterprise.Through cloud computing, enterprises can transform their IT costs from capital costs to operating expenses. Especially Elastic Cloud provides the transfer of the risk, so in the long run, to a service hosting has some value in the cloud. Cloud computing users who need to make a choice in the existing data center to the cloud hosting service, or kept in its own data center. This paper compares and analyzes the enterprise cloud computing access and use of the company’s own data center costs, specifically the daily work of the enterprise information for each cost element, and the calculation formula for each cost element. Standardized by the value of each element of the processing costs, the use of DEA model to evaluate the relative effectiveness. Based on a comparison of gray correlation between countries DEA model calculations with the data, draw the actual best decision. Provide accurate and reliable quantification decision results for enterprise computing applications and building its own data center in the cloud access.
