With increase of the network bandwidth, it is increasingly mature for networks to have access to non-local computation services (such as data processing and saving and information service), resulting in the so-called cloud computing technology nowadays.
A cloud computing integrated system based on Software-as-a-Service, Platform-as-a-Service, Infrastructure-as-a-Service, grid computing, distributed computing, utility computing, network storage, virtualization and load balancing realizes a management mode and business mode for the application field of shared clouds and private clouds.
A cloud computing system can provide 3G users with unprecedented contents and experience of service because of its great computing power, almost endless storage space and support for diversified software services. The Internet of Things acquires extremely massive data through numerous sensors (such as hundreds of millions of RFID, smart dust and video monitoring) and gathers them to the cloud computing system through 3G and broadband Internet to be processed and analyzed, realizing quicker and more accurate and intelligent management and control for the physical world and enabling human to manage production and life more accurately and intelligently for much better productivity and life quality.
