Patent attributes
Technologies are presented for a hybrid cloud-based service model combining separate database/separate schema, shared database/separate schema, and shared database/shared schema architectures suitable for serving multiple tenants while addressing varying security needs. Roles and security level needs of different tenants may be determined based on tenant declaration or inference from tenant attributes. Tenants may then be assigned to suitable clouds or sub-clouds based on their security level needs. In some examples, a claims-based access control authorization model such as federation may be employed to support interactions between the three different types of clouds or sub-clouds under the umbrella of a single cloud-based service provider while maintaining application and data security.
