Multi-tenant secure separation of data in a cloud-based application

Multi-tenant and single-tenant methodologies are blended into a single solution to provide cost savings of multi-tenancy along with data security and privacy of a single-tenant environment. The cloud infrastructure is partitioned to include a first set of servers, and a second set of servers. The first set of servers are dedicated to a first operation, such as data presentation, while the second set of servers are dedicated to a second operation, such as data processing. The first set is operated in a multi-tenant operating mode, while the second set is operated in a single-tenant operating mode. Thus, the first set is available for general use, presenting data from any of the server(s) in the second set. The second set, in contrast, is dedicated to individual tenants. Preferably, each tenant has dedicated server(s) in the second set, which functions like a traditional, single-tenant environment providing inherent security and privacy guarantees.
