Abstract: A method and apparatus for scaling cloud computing re-sources e.g. virtual network function (VNF) components in a network comprises detecting a need for increasing or decreasing one or more of virtual network function (VNF) components, the VNF components being related to a VNF. In case of decreasing, one or more of the VNF components are selected for removal and the load of the selected one or more of the VNF components is relocated or rebalanced to a remainder of the VNF components and removal of the selected one or more of the VNF components is requested. In case of increasing, one or more VNF components to be deployed is determined, the additional one or more VNF components is requested, and after receiving a command to deploy the additional one or more VNF components the load of the VNF is rebalanced between the VNF components and the additional one or more VNF components.
