It’s Here: ‘Network Virtualization for Dummies’

Today, just about all enterprise data centers have virtualized a significant portion of their server resources and a large percentage are moving to virtualizing their storage resources as well. These IT organisations are realising the payoff that comes with virtualization—things like better utilization of resources, increased IT agility, and lower capital and operational costs.

But could that payoff be even bigger? If organisations have not yet virtualized their network resources, they are basically leaving a lot of money on the table—in terms of potential capital and operational cost savings, increased data center security, and greater business and IT agility.

Those are among the benefits of network virtualization that are explored in the new “Network Virtualization For Dummies” book. This reference book, published by Wiley and sponsored by VMware, offers a crash course on the new, virtualized approach to the network that is a key building block for the software-defined data center.

In simple, straightforward language, this quick-to-read book explains the fundamentals of network virtualization, including its core concepts, key technology components, use cases, and business and IT benefits. Spend a little time with the book and you will come away with an understanding of why you need network virtualization, how it can improve your life, and what you need to do to get started.

In making the case for network virtualization, this book explains how legacy network architectures are limiting business agility, leaving security threats unchecked, and driving up data center costs. These hard realities point to a single overarching need: It’s time to move out of the hardwired past and into the era of the virtualized network.

So what exactly is network virtualization? The book explains that network virtualization programmatically creates, provisions, and manages virtual networks, using the underlying physical network as a simple packet-forwarding backplane. Network virtualization replicates all networking components and functions in software. In simple terms, it allows you to run your entire network in software.

A good thing about this book is that it tells the story of network virtualization in terms that anyone working in an IT shop should be able to understand. And better still, the book is written as a reference guide, so you don’t need to read it from cover to cover. You might want to do just that, of course, because the book is a good read all the way through. But if your time is scarce, you can jump right to the topics you are most interested in, just as you would do with any reference guide.

Either way, you will come away with an understanding of why you need to virtualize your network and what you need to do to get started.
