Economies of scale required to cover investments in hardware-based functionalities are no longer applicable for software-based development, making feasible other modes of feature evolution. Network Functions Virtualisation will enable network operators to significantly reduce the maturation cycle. The possibility of running production, test and reference facilities on the same infrastructure provides much more efficient test and integration, reducing development costs and time to market. Services can be rapidly scaled up/down as required. In addition, speed of service deployment is improved by provisioning remotely in software without any site visits required to install new hardware. Enabling a wide variety of eco-systems and encouraging openness. It opens the virtual appliance market to pure software entrants, small players and academia, encouraging more innovation to bring new services and new revenue streams quickly at much lower risk.
