The fixed granularity of virtual machines offered by IaaS providers has prompted the evolution of derivative clouds where resources are repackaged into smaller containers and leased out typically in PaaS mode. In such a setup, containers are provisioned within virtual machines. Such a nested setup results in two control centers for the resources used by those containers—the guest OS and the Hypervisor. The latter’s control actions are agnostic of the application executing within a VM. This lack of visibility may result in hypervisor control that has a non-uniform effect on the VM’s nested containers which is undesirable. In this work, we propose policy based control of the effect of the hypervisor’s control actions amongst the containers nested in the affected VM.
