云计算背景下企业IT 决策机制框架

云计算的不同应用水平会在不同程度影响企业的IT决策，相应的IT决策机制也会随之发生变化．本文深入分析了云计算的三层服务模式对IT决策的影响，由此提出了基于云计算背景的IT决策机制框架．并通过国外成功实施云计算的企业案例分析并验证本文得出的IT决策机制框架．本文不仅对以往的IT决策机制框架的基础上加入了IT服务模式维度，同时也为云计算在企业中的应用提供了制度框架．

Framework of Enterprise IT Decision-Making Mechanism framework in Cloud Computing Environment

The effect of different level of cloud computing applications on different IT decisions vary differently, and the mechanisms of IT decisions will change at the same time. This paper has analysis the impacts of three service modles of cloud computing on IT decisions and put forward a new IT decision-making mechanism framework. Then, this paper use an case about a oversea enterprise which using cloud computing successfully to analysis and test the decision-making mechanisms framework this paper has proposed before. This paper only add a new dimension of three service modles of cloud computing to the original framework, but also provide a regime framework for enterpeise applying cloud computing.
