As I noted in Part 1 of this series, the communications industry is abuzz with vendor and service provider interest in the NFV space. With the potential to completely transform the way communication networks are designed, built and operated, NFV promises a number of benefits such as reduced capital (CAPEX), reduced operational (OPEX) expenditures, reduced time for service turn up and a shift to a “fail fast” model for new services.
In part 1, we highlighted some of the key industry initiatives, such as the ETSI NFV ISG, that are driving the adoption of NFV, but emphasized that there are two further areas where innovation must take place in order for NFV to be successful. We noted the areas that have not received as much attention thus far: Firstly, the business models for virtual network functions (VNFs) and secondly, how VNFs are authored for the cloud. Part 1 examined the NFV business models. In this part, we look at VNF authoring for the cloud.
