Cloud computing can meet the current big data processing needs, so a variety of major companies are competing to increase investment in cloud computing on the basis of existing knowledge. The deployment of cloud computing platform, the development of cloud computing technology and the implementation of cloud services all derived from cloud computing are achieving rapid development. In addition, with localized client toward recession, people want to be able to get data anytime, anywhere they want. Cloud computing is regarded as a new model of computing application, wishing it bring big changes to IT industry has been a long-held dream. Cloud computing with its efficiency, reliability, scalability and high load capacity, has been more and more widely accepted. The cloud-based applications have brought a significant change to the devel
