A Visual Guide to Understanding Software DefinedNetworks andNetwork Function Virtualization The simple, visual, at-a-glance guide to SDN and NFV: Core concepts, business drivers, key technologies, and more! SDN (Software DefinedNetworks) and NFV (Network Function Virtualization) are today’s hottest areas ofnetworking. Many executives, investors, sales professionals, and marketers need a solid working understanding of these technologies, but most books on the subject are written specifically fornetwork 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 virtualizations. 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 virtualization enables SDN and NFV; how datacenters are virtualized through clouds; hownetworks can also be virtualized; and how to maximize security, visibility, and Quality of Experience in tomorrow’s fully-virtualized environments. Step by step, you’ll discover why SDN and NFV technologies are completely redefining both enterprise and carriernetworks, and driving the most dramatic technology migration since IPnetworking. That’s not all: You’ll learn all you need to help lead this transformation.
  • Learn how virtualization establishes the foundation for SDN and NFV
  • Review the benefits of VMs, the role of hypervisors, and the management of virtual resources
  • Discover how cloud technologies enable datacenter virtualization
  • Understand the roles ofnetworking gear in virtualized datacenters
  • See VMWare VMotion and VXLAN at work in the virtualized datacenter
  • Understand multitenancy and the challenges of “communal living”
  • Learn how corenetwork functions and appliances can be virtualized
  • Ensure performance and scalability in virtualizednetworks
  • Compare modern approaches tonetwork virtualization, including OpenFlow, VMWare Nicera, Cisco Inseieme, and OpenStack
  • Walk through the business case for SDN, NFV, and the Cloud
  • Discover how the Software DefinedNetwork (SDN) solves problems previously left unaddressed
  • Understand SDN controllers–and who’s fighting to control yournetwork
  • Use SDN and NFV to improve integration and say goodbye to “truck rolls”
  • Enforce security, avoid data leakage, and protect assets through encryption
  • Provide for effective monitoring and consistent Quality of Experience (QoE)
  • Learn how SDN and NFV will affect you–and what’s next
