A Method and System of Migrating Data for Multi -

The cloud-based applications is popular. And the cloud computing is convenient for end users, who can access many kinds of service by browser. To support the well-suited facility and flexiblebusiness, there are complex and huge of configurable data in the background data center of cloud for infrastructure, platform and application. And to reduce the cost of cloud, Multi-tenant is selected by many service provider in cloud. And there are many different substantiality to uphold the Multi-tenant applications in cloud computing, such as database, LDAP, content management system(CMS), application server etc. With the business grow or to provide more high quality of service, or to maximize customer satisfaction, the applications of one or multiple tenants in cloud need be reorganization for capacity management or from staging to production. It is a gigantic challenge to identify and migrate these data of tenant in different entities from one cloud environment to another tenant of new cloud environment. How to transfer these commixed data lightly and fast only for one tenant in different entities(DB, LDAP, CMS) of cloud environment to one new tenant of another cloud environment is more difficult .

In some case, the data from different tenants could exist in the same entity, such as database and content management system; or in the different entry level of the same entity, such as LDAP. Currently, there is no universal tool to identify and export these mixed data in different data objects for one tenant in cloud computing environment. Of course there is some utility commands, such as 'export', in

database software, but these commands are used for general purpose, which can not filter the specifically data for business perspective, such as one tenant data existing in table , view, trigger and sequence of one database etc .

The invention is that automatically distinguish, filter and export one tenant's data information from the different data entities, such as database, LDAP, Content Management System, in the cloud computing environment; then migrate these exported tenant's data from the source cloud to another target cloud computing environment. And the identify rule is user-defined to support the different data entities. And the identify rule is compiled by XML format file .

The Cloud Data Migration System will parse the control and rule file, which is XML format. And the program can get the different data source access information in the cloud environment. And the XML file also contains the user-defined rules about how to identify the data for the special tenant. These tenant rule identifier could be named 'Unique Tenant Identifier', which is used to filter the data in different entiti...
