「Cloud computing is a way of a service through the network to provide dynamic scalable virtualized resources.」


Dynamic Resource Allocation:
Dynamically according to consumer demand or released into different physical and virtual resources, while increasing a demand, by increasing the available resources can be matched to provide flexibility of resources quickly; if the user does not use this part of the resource, can be released these resources. Cloud computing provides customers this ability is unlimited, the use of IT resources to achieve scalability.

Demand Self-service Technology:
Cloud computing technology to provide customers with self-help resources services, users can automatically without interaction with the provider's computing resources to obtain self-help skills. Meanwhile cloud systems to provide customers with certain application service catalog, customers can use self-service options to meet their needs of services and content.

Network-Centric:
Cloud computing components and the overall architecture consists of networked together and exist in the network, and provide services to users via the network. And customers can take advantage of different terminal equipment, through the application of standards for network access, making cloud computing services everywhere.

Service can be Quantified:
In the course of providing cloud services for different types of customers, through the metering method to automatically control and optimize resource allocation. Namely the use of resources can be monitored and controlled, is a pay as you go service model.

Pooling of Resources and Transparency:
The cloud service providers, the various underlying resources (computing, storage, networking, resource logic, etc.) heterogeneity (if there is some heterogeneity) is masked, the boundary is broken, all resources can be unified management and scheduling, as so-called "resource pool", which provides users with on-demand services; for users, these resources are transparent, infinitely large, the user need not know the internal structure, only care about their needs are met can.
