A method includes executing a Virtual Network Function (VNF) that includes a plurality of VNF components supported by a plurality of virtual machines, the virtual machines supported by a set of physical machines, the plurality of VNF components comprising a first group of VNF components and a second group of VNF components that is different than the first group, both the first group and the second group being independently scalable. The method further includes scaling the first group of VNF components in response to a change in demand for services associated with the first group.
