Data storage technology has been developing for many years. There are many different ways to store data. So far, database is still one of the main techniques for storing structured data. With the need of big data, application system faces many problems in management, divided into two aspects. First, most data migration methods are inefficient and insecure. As a result, a single host data storage and service capabilities cannot meet the entire application system, so it is necessary to build a cloud database system. In order to ensure the reliability of multi-cloud host operations, it is necessary to carry out frequent data migration operations and dynamic migration of cloud databases between different hosts. Secondly, there are problems of low maintenance efficiency and high cost. Because the traditional database management is in the cloud platform, it is not conducive to remote management operations. Therefore, this paper develops a system to manage multiple host databases in a unified manner, which can not only simplify the operation steps, but also improve the security and operational efficiency of the data. In method, there are manual, automatic, and advanced migration database, and so on. Experimental results show that in the environment of virtual machines, the advanced method of migrating database is superior to the other two methods in terms of security and efficiency.
