Cloud computing is through connect running a server, the server may for data transmission, data is like the "cloud" on the network between different servers "gone with the wind", through the network to provide customers with services at the same time,
Second, resources controlled
Cloud computing is put forward, is to let people can like using water and electricity and convenient use of cloud computing service, great convenient access to computing resources, and greatly providing computing resource utilization rate, effective cost savings, makes the resources to a certain extent, belongs to the category of "control", but how to reasonable, the cloud computing service effective billing, remains a concern of the industry concerned,
Three, on-demand service
The scale of the "cloud" is to dynamically scale, at the time of using cloud computing services, computer resources is gained by the users according to user's individualized demand increase or decrease, and on this basis to pay for their own use of the service,
Four, resource pooling
Resource pool is of all kinds of resources (e.g., storage resources, network resources) unified configuration of a configuration mechanism, from the user's point of view, do not need to care about equipment types, and the complex structure of the internal, implementation method and the geographical location, just care about what you need service, from the Angle of resource managers, resource pool is the main benefit of nearly infinite to increase or decrease and replacement of equipment, and management, scheduling resources is very convenient,
Five, safe and reliable
Cloud computing must ensure the sustainability of service, security, efficiency and flexibility, so for providers, must adopt all kinds of redundancy mechanism, backup mechanism, safety management mechanism and guarantee enough access to huge amounts of data of flexible mechanism, etc., so as to ensure the safe and reliable data and service of users, for users, as long as you pay a fee, you can get supplier to provide the professional level of security protection, save a lot of time and effort,
