DATA MANAGEMENT IN A MULTI-TENANT DISTRIBUTIVE ENVIRONMENT

摘要

The present invention relates to a method and apparatus for data management in multi-tenant distributive environment. According to the embodiments of the present invention, a tenant-specific virtual metadata server may be created and registered with a task manager in a job processing system. The virtual metadata server provides a tenant-specific logical file system namespace. Any access to tenant data will be performed via the virtual metadata server. In other words, such virtual metadata server acts as an interface between a tenant terminal and an entity file system. In this way, it may effectively realize isolation of tenant data and enhance data security. Moreover, by using a virtual metadata server rather than physically isolating user data, the embodiments of the present invention may guarantee the efficiency of data sharing while improving the data security.
