A method, system, and/or computer program product configures hierarchical cloud resources. A supervisor server receives a signal indicating a boundary of a set of hierarchical cloud resources. The boundary describes a level of resource sharing among the set of hierarchical cloud resources, which includes a set of software applications, a set of middleware that supports one or more software applications from the set of software applications, and a set of virtual mechanisms that supports one or more middleware from the set of middleware. The supervisor server receives a signal from one or more Isolation/Density (I/D) switches, which are associated with one or more software applications from the set of software applications and one or more middleware from the set of the middleware, and then configures the hierarchical cloud resources, according to the boundary of the set of hierarchical cloud resources, and according to settings of the I/D switches.
