A major transformation in the world of networks is underway, as the focus shifts from physical technology to software-based solutions. In this book, the authors present this new generation of networks that are based in the Cloud by detailing the transition from a complex environment to a simple digital infrastructure. This infrastructure brings together connected devices, the antennas that collect radio waves, the optical fibers that carry signals and the data center that handles all of the different processes. From this perspective, the data center becomes the brain, managing network services, controls, automation, intelligence, security and other applications. This architecture is relevant to carrier networks, the Internet of Things, enterprise networks and the global networks of the major Internet companies. Cloud Networking is revolutionizing the field of networks by proposing a complete paradigm shift. The Cloud imposes a completely different vision of the Internet with centralized controls and a virtualization of all the functions necessary to the life of a network, the latter consisting of the replacement of hardware equipment by software equipment which runs in the Cloud. As a result, physical networks are replaced by logical networks that run in data centers that are more or less remote from the network nodes themselves.
