Cloud Computing is the combination of Distributed Computing, Parallel Processing and Grid Computing, or also know as the computer science concept of business.
Many multinational company such as the information technology industry, Yahoo and Google IBM’s use of the concept of cloud calculative selling their products and services. Cloud calculative this term may be borrowed from the quantum physics of Electron Cloud “(” Cloud), emphasize that the calculation of diffuse and omnipresent distribution and social characteristics. In quantum physics “probability cloud)”, electron (around the nucleus in electronic is not a sport such as the rail track objects, but as the space, cloud filled the existence of the movement is described, electronic Newton classical mechanics but a probability distribution density function, use the schrodinger equation to describe fluctuations within the time specified, the probability of a particle size, with the formulation of the classical mechanics is totally different. Has the following characteristics of cloud, however, diffuse, simultaneously, etc., may indeed is calculated from the clouds cloud concept, this is the so-called “before the Ubiquitous computing”, IBM has a Ubiquitous computing is Ubiquitous “, “MS (Bill) soon followed a Ubiquitous computing” Pervade “, people is right now Ubiquitous computing is a new understanding, now say “Omnipresent”. However, the cloud calculative is purely commercial hype, it will change the pattern of information industry, now many people already use Google Apps and Google Doc, USES the many remote software applications such as word processors Office rather than with your local machine install these applications, who will buy Office software? There are many enterprise applications such as e-commerce applications, such as to write a transaction procedures, Google’s enterprise scheme and contains the templates, a salesperson didn’t study Netbeanr also can make. This calculation and industry trends is the source of the spirit, with a Service SaaS (on) the trend. Now, there’s only five computers in the world today, is a Google, one is the IBM, is a Yahoo, one is amazon.com, is a Microsoft, because these five company takes the lead in the distributed processing business applications on the leading the trend. From very early computer network is proposed that “is prescient.
