Cloud computing is an information processing method realizing the large-scale computing by uniformly organizing and flexibly allocating various information resources through the network. “Cloud” is a metaphor of the service mode and technical realization of cloud computing, which utilizes the distributed computing and virtual resource administration to collect the distributed ICT resource to form the sharing resource pool and provides the user with the service in a dynamic measurable way according to the demand. User may obtain the ICT resource service through the network by various kinds of terminals (i.e. PC, tablet PC, smart phone or even smart TV).

Early in 2008, major international IT enterprises including Cisco, HP, Dell and EMC established a special department to promote the cloud computing technology and market progress, and gradually released the cloud computing strategy, such as “VCE Union” consisting of Cisco, EMC and VMware. Some cloud service enterprises in the world have been capable of providing the large-scale global cloud computing service and are guiding the technical development direction of the cloud computing. Chinese cloud computing service market is in the initial stage and the cloud computing technology and equipment have been developed to a certain extent. Chinese cloud computing service market is generally quite small but the development trend is obvious. It is estimated by Gartner that China only occupies less than 3% of the global cloud computing service market in 2011, which values about USD 90 billion, but the annual growth rate reaches 40%, and it is expected that the gap between Chinese and foreign cloud computing capability will be gradually shortened. The large-scale Internet enterprise is the major cloud computing service supplier in China, whose business form focuses on the open platform service of IaaS+PaaS, among which IaaS service is more mature while PaaS service is just formed.

Cloud computing service can be divided into IaaS (infrastructure as a service), PaaS (platform as a service) and SaaS (software as a service) by the layer of the provided resource. Cloud computing can be also divided into private cloud for the internal use, public cloud for the public use and mixed cloud for combined use. Cloud computing industry includes infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS).
