Multi-tenant data isolation scheme applied to PaaS (Platform-as-a-Service) platform

Abstract

The invention discloses a multi-tenant data isolation scheme applied to a PaaS (Platform-as-a-Service) platform. According to the multi-tenant data isolation scheme, database configuration of a heterogeneous system is registered in a configuration file Datasource.xml; a hybrid data isolation mode is employed; moreover, data isolation of a toB level and a toC level is compatible; according to the configuration file Datasource.xml, database configuration information of the heterogeneous system is appointed; mapping information based on orientation to one or more source databases and multi-tenant metadata are provided; carried own tenant ids are established for the tenants when different systems log in a current cloud application system. According to the technical scheme, demands of the two fields of toB and toC are compatible, and scalability, expansibility and shareability are integrated.

Description

technical field [0001] The invention belongs to the field of computer software cloud computing, and in particular relates to a multi-tenant data isolation scheme applied to a PaaS platform. Background technique [0002] With the development of cloud computing technology and the maturity of virtualization technology, PaaS (the abbreviation of Platform-as-a-Service, meaning platform as a service) has become a hotspot of cloud computing applications, and traditional software application vendors are constantly transforming to the cloud. The server platform or development environment is provided to users as a service, and the provider is responsible for managing and maintaining resources to effectively reduce the cost of SaaS applications. [0003] The multi-tenant architecture is one of the most important models on the PaaS platform, which provides strong support for the practical application of the PaaS platform. At the architectural level, the multi-tenant architecture ensure...

Problems solved by technology

An independent database refers to a tenant who exclusively owns a database instance. Tenant data is not physically visible to each other, and backup and recovery are very flexible; shared databases and independent schemas associate each tenant with a different schema of the same database, and the data between tenants is logical. Invisible, the implementation of the upper-level application is as simple as an independent database, but the backup and recovery are slightly more complicated; the last mode is that tenant data is shared at the data table level, which provides the lowest cost, but introduces additional programming complexity (The data access of the program needs to use tenantId to distinguish different tenants), and the backup and recovery are more complicated
