By the way, IT people introducing virtualised servers to help reduce the cost of software licensing need to be aware of a nightmare scenario. This is when software is used in this way, works perfectly to start with and users depend upon it and save their information with it. Then the software stops working and the software vendor can't or won't support it. The users will not be happy.
It's a bit dry to read but I guess virtualisation is never going to set the heather on fire interestingwise.
Most Helpful Customer Reviews on Amazon.com (beta) (May include reviews from Early Reviewer Rewards Program)
As much as I think Virtualization for Dummies will help implementers who touch actual metal, I believe it to be an even greater resource to those of us who don't. Or as one reviewer so artfully termed our type, "paratechnologists": technical writers, corporate communicators, perhaps even procurement people, who can't afford to fake comprehension. In other words, anyone who needs a really solid understanding of mission critical technologies without actually using them.
To this end, Bernard Golden helps us non-IT folks talk the talk, and just as importantly, be able to explain it effectively to others.
Despite Virtualization for Dummies' publication several years ago, it still holds up well under the relentless onslaught of Moore's Law and IT innovation in general. If there was one area I might say it may finally be showing its age, it would be in the treatment of storage options. DAS, SANs, and many esoteric options (esoteric to me, anyway, Mr. Para-tech) are covered, but the book doesn't really address the explosion of third-party, cloud-based storage, which only in recent years has become robust, secure, and reliable enough for businesses. It's a small omission, and not one for which the author could be faulted, given the publication date.
Golden, an MBA, did a laudable job of explaining how to present virtualization to the C-suite using spreadsheets and calculating net present value. This was the subject of a white paper I wrote a few years back and I could have saved a ton of time and research by simply reading that chapter. That section might be summarized as, "learn to talk the language of finance." If you have an aging data center and need a template for making the case to virtualize those energy-hog servers, the book pays for itself on that basis alone. Skip bringing in the pricey consultant, read Chapter 6, and open up Excel!
Speaking of pricey consultants, I also applaud Golden for his tongue-in-cheek jabs at "guru" consultants -- who parade around like emperors in new clothes -- as well as some vendors with their say-anything-to-sell-it promises. It's easy to get sold a bill of goods in this business, and it's the stuff of which IT jobs and careers are ruined. The author duly points out the landmines. And, very importantly, he gives a balanced and nuanced view of instances where virtualization is NOT appropriate. Best to go in with your eyes open about the technology's limitations (for instance, it can be a deadly resource vampire with your high-performance applications).
In conclusion, if you have anything to do with virtualized systems in your enterprise, this book belongs on your bookshelf. Don't be embarrassed that people might see the black and yellow cover and think less of you for it -- just get the book and read it!
