SDN and NFV Simplified: A Visual Guide to Understanding Software Defined Networks and Network Function Virtualization

SDN (Software Defined Networks) and NFV (Network Function Virtualisation) are today’s hottest areas of networking. Many executives, investors, sales professionals, and marketers need a solid working understanding of these technologies, but most books on the subject are written specifically for network engineers and other technical experts. SDN and NFV Simplified fills that gap, offering highly visual, “at-a-glance” explanations of SDN, NFV, and their underlying virtualisations. Built around an illustrated, story-telling approach, this answers the questions: Why does this technology matter? How does it work? Where is it used? What problems does it solve? Through easy, whiteboard-style infographics, you’ll learn: how virtualisation enables SDN and NFV; how datacenters are virtualised through clouds; how networks can also be virtualised; and how to maximise security, visibility, and Quality of Experience in tomorrow’s fully-virtualised environments. Step by step, you’ll discover why SDN and NFV technologies are completely redefining both enterprise and carrier networks, and driving the most dramatic technology migration since IP networking. That’s not all: You’ll learn all you need to help lead this transformation.
