0 Introduction Cloud computing is a new manifestation of the development of science and technology such as distributed processing, parallel processing and grid computing. It provides subscribers with a customizable virtual computing environment through a powerful and reliable computing resource platform, simplifying the use of computing resources Form, reducing the cost of building a computing environment for users to enable users to have real-time access to the network, storage, computing, and the like. Cloud computing provides dynamic resource pools through virtualization to make the availability of resources more efficient. With virtualized storage technology, users can manage growing data and information in the most cost-effective and cost-effective manner with minimal resources, simplifying the complexity of managing heterogeneous operating environments
