Cloud computing (cloud computing) is a kind of distributed computing, refers to the network "cloud" will be huge data computing processing program is broken down into countless small programs, and then, through the system composed of multiple servers to process and analyze these small programs to get the results and return to the user. In the early days of cloud computing, simply put, it was simple distributed computing that solved the problem of distributing tasks and merging the results of calculations. Thus, cloud computing is also known as grid computing. With this technology, the processing of tens of thousands of data can be done in a very short period of time (a few seconds), resulting in powerful web services. [1]

At this stage what is called cloud services is no longer just a distributed computing, but a result of the evolution and leapfrog of a mixture of computer technologies such as distributed computing, utility computing, load balancing, parallel computing, network storage, hot backup redundancy and virtualization.

Overview

"Cloud" is essentially a network, narrowly speaking, cloud computing is a network that provides resources that users can access at any time. Access to resources on the "cloud", according to the demand for use, and can be seen as unlimited expansion, as long as the amount of use to pay for it, the "cloud" is like a water plant, we can always pick up the water, and unlimited, according to their own water consumption, pay for the water plant can be. The "cloud" is like a water plant. [2]

Broadly speaking, cloud computing is a service related to information technology, software, and the Internet, and this pool of computing resources*** is called "the cloud". Cloud computing aggregates many computing resources and automates their management through software, which requires very few people to be involved in order for the resources to be rapidly available. In other words, computing power as a commodity, can be circulated on the Internet, just like water, electricity and gas, can be easily accessed, and the price is relatively low. [2]
