云计算(cloud computing)是一种崭新的计算模式,它将计算任务分布在大量计算机构成的资源池上,使各种应用系统能够根据需要获取计算力、存储空间和信息服务。国家“十二五”规划纲要及《国务院关于加快培育和发展战略性新兴产业的决定》,均把“云计算”作为新一代信息技术产业的重要部分加以强调。目前,云计算在我国商业领域应用已经比较广泛,表现突出,然而在电子政务领域却几乎没能加以应用。 Cloud computing is a new computing paradigm that distributes computational tasks over a pool of resources made up of a large number of computers, enabling various applications to gain compute power, storage space, and information services as needed. The national “Twelfth Five-Year Plan” and “Decision of the State Council on Accelerating the Cultivation and Development of Strategic Emerging Industries” all emphasize “cloud computing” as an important part of the new generation of information technology industry. At present, cloud computing has been widely used in commercial areas of our country, with outstanding performance. However, it has hardly been applied in the field of e-government.
