Cloud computing is a type of computer that is based on the sharing of computer resources than local servers or personal devices to handle applications. Cloud computing can compare to grid computing, a type of computer that unused processing cycles of all the computers in a network are harnessed to solve the problem of too intensive for any independent machines.In cloud computing, cloud computing from (also phrased as "clouds") is used as a metaphor for the "Internet", so the phrase cloud computing means "a kind of Internet-based computing", where different services-such as servers, storage, and applications-are assigned to the computer and the device of an organization through the Internet.How Cloud Computing worksThe goal of cloud computing is to apply traditional supercomputers, or high-performance computing, often used by the military and research base, made tens of thousands of billions of calculations per second, in the application of the consumer-oriented as the finance portfolio , provide personal information, to provide data storage or to large power supply, computer role-playing game online.To do this, use the network cloud of large groups of servers typically run computer technology of consumers at a low cost with professional connections to spread the data processing work on them. the IT infrastructure contains a large pool shared systems are connected to each other. Usually, the virtualization technique used to maximize the power of cloud computing.Cloud computing standardsThe standard for connecting computer systems and the software required to make cloud computing work is not fully defined at the present time, leaving many companies to define cloud computing technology of their own. cloud computing systems offered by companies, such as IBM's technology "Blue Cloud", for example, are based on open standards and open source software have to link computers together are used to provide Web 2.0 capabilities such as mash-up or mobile commerce.Cloud computing in the data center and for small businessCloud computing has started to get embroiled in the company's data center because it allows data centers to activities such as the Internet, through the process of creating the conditions for computer resources to be accessed and shared as virtual resources safely and scalability.For a small and medium scale businesses (SMB), the benefits of cloud computing are currently driving adoption. In the SMB sector often have a lack of time and financial resources to purchase, deploy and maintain an infrastructure (e.g. software, servers and storage).In the cloud, small businesses can access the resources and expand or shrink the services as business needs change. Popular pay-as-you-go subscription model is designed for SMBs to easily add or remove services and you'll usually pay only for what you use.
