In addition, with the increase in business and applications system to face the massive data storage and improve system scalability requirements. The emergence of cloud computing provides an opportunity to address the issues. Cloud computing technology as a computing model, the important feature is the integration of resources, it is easy to maintain, highly scalable technology capability makes cloud computing more and more attention and application.
