On-demand service is the paradigm that reflects the way that users want to access their applications today. In the last decade, the technologies were adapted to this `User Centric' approach, but they still do not reach a large number of users. A necessary transformation and innovation must continue to progress! The questions that we address in this chapter are: What evolution should allow this objective? What are the fundamental novelties that would enable us to improve the agility of the network in dynamic and competitive environments? Thus, we analyze the models of: Cloud, Virtualization, Programmability and the `As a Service' model. This analysis will enable us to consider a convergent global view for the near future, with more pragmatism of the digital world to offer the hyper-connectivity desired by users.
