In 2006, the concept of “cloud” was formally put forward. Then a series of “cloud” came out of the sky. E-commerce, the rapid development of online video, the explosive growth of data volume, but to store and maintain such a large amount of data, not only requires a lot of server equipment, but also consume a huge Electricity and human resources. Many software is free, and buying is not cost-effective for users who do not use the software infrequently. Is there a resource that we can use when we need it and go back when we do not need it? Yes, this is Cloud Computing. Through the establishment of a network server cluster, to provide different types of customers online software services, hardware rental, data storage, calculation and analysis of different
