Abstract

See full text

A multi-tenant software program is maintained in a computing environment having a plurality of compatible instances of the program, each adapted to serve a plurality of tenants, with each controlling corresponding individual data. The method includes: receiving a maintenance request for a target instance, the target instance having one or more target tenants each controlling corresponding target individual data; selecting an auxiliary instance from other instances different from the target instance; providing the target individual data of each target tenant to the auxiliary instance; redirecting each target tenant by forwarding each target tenant request to the auxiliary instance; applying a maintenance operation on the target instance according to the maintenance request; returning the target individual data of each target tenant from the auxiliary instance in response to the applying of the maintenance operation; and restoring the serving of each target tenant request by the target instance.
