Book Description

Virtualization has become a “megatrend”—and for good reason. Implementing virtualization allows for more efficient utilization of network server capacity, simpler storage administration, reduced energy costs, and better use of corporate capital. In other words: virtualization helps you save money, energy, and space. Not bad, huh?

If you’re thinking about “going virtual” but have the feeling everyone else in the world understands exactly what that means while you’re still virtually in the dark, take heart. Virtualization for Dummies gives you a thorough introduction to this hot topic and helps you evaluate if making the switch to a virtual environment is right for you.

This fun and friendly guide starts with a detailed overview of exactly what virtualization is and exactly how it works, and then takes you on a tour of the benefits of a virtualized environment, such as added space in overcrowded data centers, lower operations costs through more efficient infrastructure administration, and reduced energy costs through server consolidation.

Next, you’ll get step-by-step guidance on how to:

  • Perform a server virtualization cost versus benefit analysis
  • Weigh server virtualization options
  • Choose hardware for your server virtualization project
  • Create a virtualized software environment
  • Migrate to—and manage—your new virtualized environment

Whether you’re an IT manager looking to sell the idea to your boss, or just want to learn more about how to create, migrate to, and successfully manage a virtualized environment, Virtualization for Dummies is your go-to guide for virtually everything you need to know.

OK, I've been in this business too long: The first time I hear a new, impressive-sounding IT buzzword, I flinch.

Part of my problem is that I've seen way too many stale old ideas rebranded by slapping fancy labels on them, an effect that often seems to happen about every four years. My suspicion is that four years is the optimal time for suckering a new generation of buyers fresh out of college into thinking they are getting something new. I still recall diving into a supposedly semi-autonomous "agent-based application" and discovering that its "agents" were actually nothing more than calls to ordinary functions.

I've also seen too many cases where a single-vendor idea that succeeds in a narrow market niche gets generalized into a "trend" that then is applied blindly whether it works or not. Gartner has labeled this kind of overgeneralization the "Hype Cycle," for good reason. When good ideas are generalized by those who do not understand their original context, they seldom work well, and in the worst cases they can turn into truly spectacular IT disasters.

Thus it when I first heard the term "virtualization" some time ago... I flinched. My thoughts went something like this:

"Yeah, right. Sounds to me like someone borrowed an impressive computer science word to help sell a product that will end up sitting on a shelf in the IT room. And by the way, isn't 'virtual' pretty much a synonym for insanely slow? The kind of stuff that they show in demos in university labs, but which in the real world would bring even the largest data center down to its knees?"

So what, one might well ask, was this curmudgeon's reaction when I picked up a copy of Bernard Golden's book, "Virtualization for Dummies"?

Somewhat to my own surprise, it was favorable.

4.0 out of 5 stars Great Primer for Beginners March 30, 2008
"Virtualization for Dummies" is intended to provide the non-technical or para-technical reader (e.g. technology procurement analysts, technical writers, project managers) with a thorough but still high-level understanding of virtualization technology. The initial chapters describe the `nuts and bolts' of the technology itself including it's benefits and limitations, the main products in the field, and how it actually performs its magic. While parts of this can get a little technical, the author does an admirable job of demystifying the basic concepts and practices of Virtualization.

The remainder of the book expands into a variety of sub-topics that include such things as hardware evaluation and selection, cost-benefits analysis, and implementing virtualization using various, industry-standard products. Readers can choose the chapters and sub-chapters that best suit their needs and skim through the balance.
Bernard Goldman is clearly very experienced in both virtualization technology itself and general IT process management. Although he does get a little beyond the book's original objectives at times, this results in a good deal of insight about the reality of deploying a virtualized environment. Using anecdotal stories and frequent, humorous observations he's produced a highly readable and very instructive volume.

Two things that might improve its impact are some strategically placed diagrams to illustrate some of the more abstract concepts; and a short glossary explaining some of the technology terms that invariably creep into any computer publication. Otherwise this is a surprisingly capable primer and I give it a solid 4 stars for its content, organization, and readability.

A great book!!! As an industry consultant and Technical Advisor to several companies struggling with their expanding requirements for fault tolerant infrastructure, I found this book to be the most useful so far for IT technologists and decision makers who need to get their arms around the ramifications of all of this. I was familiar with Bernard Golden's CIO magazine articles and insightful book "Succeeding with Open Source" and was pleased to discover he had also written a book covering the fast moving and diverse topic of Virtualization. It is written in a conversational style that contains very clear, succinct conceptual information and technical details interspersed with very pertinent and well-focused stories. The writing style and very well organized structural approach to the topics makes this book very readable by technology analysts, CIOs, and technical project managers who need to be able see the big picture of the "forest through the trees" in order to understand the total corporate ROI issues with virtualization technology. Conversely, the book is well suited to industry technologist and software engineers who want to obtain a quick basic working knowledge of the "detailed roots" of the virtualization technology but otherwise would never have been exposed to the broader applicability and global consequences of this very fundamental nuts-and-bolts software.

The well-organized structure of the book as independent parts, each containing independent chapters, makes it possible to pick and chose what information or level of technical detail is of interest to the reader while still allowing for interrelated topics to be introduced in the proper logically dependent sequence.
