Cloud computing is a new way of Internet-based computing that enables individuals and business users to access computing and services in an on-demand, easily scalable way. So do you know what are the characteristics of cloud computing?
Cloud computing centers generally have a very large scale. Cloud computing is to provide cloud computing services to the entire market, the user's computing resources are used from the "cloud", so only the "cloud" is large enough to undertake cloud computing services.
For example, Google cloud computing center has been several million servers, and Amaon, lBM, Microsoft-Yahoo and other companies control the scale of cloud computing is no less.
Cloud computing breaks through the boundaries of time and space, which is the most significant feature of cloud computing. Virtualization contains two kinds of application virtualization and resource virtualization. The application of cloud computing is provided remotely through the network, and the resources are also located in the "cloud", for users, both are virtualized.
The cloud computing center adopts hardware and software level such as multi-copy data fault tolerance, heartbeat detection and computing node isomorphism interchangeable to ensure high reliability of services.
Cloud computing has efficient computing capacity, and adding cloud computing functions on top of the original server can rapidly increase the computing speed and eventually achieve the purpose of dynamically expanding the virtualization level to scale the application.
On-demand service distribution
Cloud computing's '"cloud" is a huge pool of resources, and users can buy computing power according to their needs. The cloud computing center will also dynamically allocate resources according to user needs.
Wide network access
Cloud computing can be accessed by multiple users at the same time and provide resource services to them, which has wide network access characteristics.
Cloud computing's on-demand service allocation avoids server resources being wasted and saves energy. In addition, cloud computing centers are generally deployed in areas with abundant but less developed power resources, while cloud computing users multiple developed areas with tight power resources, saving energy through reasonable geographic resource allocation.
