The emergence of concepts like cloud computing, SDN, and ultimately NFV is expected to raise new possibilities for the management of Service Functions (SFs), with a positive impact in terms of agility and cost.

From a telco viewpoint these concepts can help to both reduce OPEX and open the door to new business opportunities. In this article, we identify how telcos can benefit from the above mentioned paradigms, and explore some of the aspects that still need to be addressed in the NFV domain. We focus on two major aspects: enabling telco infrastructures to adopt this new paradigm, and orchestrating and managing SFs toward telco-ready cloud infrastructures.
