A friend recently showed me a demo of his latest project, a 3D simulation of a data center. In the demo, your avatar would walk around the rows of racks in a virtual representation of your physical facility. With a click of the mouse, a server in a rack would open like a drawer and a little status screen would emerge and hover in the air in front of your virtual data center administrator. “That’s a really fun demo,” I told my friend, “but it would have actually been useful even five years ago. Now? Not so much.” My friend, who had been in the software industry for 30 years, had missed the wildfire impact that virtualization has had on the IT industry. The hardware is still there, racked up and plugged in, but the physical server is no longer the unit of work or the unit of management in the data center. We no longer look at one physical machine at a time; we manage entire data centers in a single pane of glass. And just as I don’t care exactly which disk sector my bits are stored on, in most cases these days I don’t care which physical server my applications are running at the moment—or even my desktop. (I’m happy to report my friend has seen the light and is now building a virtual representation of his virtual infrastructure.) The wave of x86 virtualization technology from VMware and others has enabled this transformation, but the benefits of the technology are what have supercharged the velocity of the change. My employer, VMware, reports its 130,000 customers can reduce hardware and operating costs by as much as 50%, reduce energy costs by 80%, reduce the time it takes to provision new servers by up to 70%, and save more than $3,000 per year for every server workload virtualized. Usually the savvy IT professional takes marketing numbers from a vendor with a grain of salt, but just talk to your fellow IT professionals for confirmation. Every day on blogs and social networks, I see messages pass by like “I Love VMware,” “Snapshots saved my bacon once again,” and “Entering maintenance mode, watching production servers VMotion while eating lunch at my desk.” One of the paradoxes of virtual infrastructure is that most things are the same as physical infrastructure, while at the same time being completely different. You’re running the same applications in the same topologies. You can treat the applications basically the same as you had been doing previously—after all, from inside the virtual machine, the workloads think they’re still back in a physical box. But at the same time, virtualization touches and transforms every part of the enterprise software stack: networking, storage, security, disaster recovery, management, provisioning, and other business processes, and even how you handle the financials. As a result, the syllabus for a virtualization training class often looks like a complete university curriculum in information technology because it has to touch on all these areas. Virtualization experts are the mixed martial artists of IT—experts in kicks, punches, throws, and wrestling moves. Because of this breadth of impact, virtualization can be daunting. VMware has had a robust set of user forums for years, where the storage expert and the networking expert can come together and help each other with their virtual infrastructure projects—and both become virtualization experts in the process. By now, the VMware Communities is the best enterprise software online community I’ve ever seen, and by far the best place to ask a quick or not-so-quick question about your virtual infrastructure. There you’ll often see esiebert 7625, the author of this book, answering questions and adding to the conversation. Eric Siebert is a natural encyclopedist and cataloguer. You can now find more information about VMware online than most of us can comfortably digest—documentation, white papers, presentations, blogs, wikis, magazines, and community sites abound. On the Communities, Eric has a knack for not only answering your question, but also always seeming to have a set of links to resources that explain the answer and give you a mini-course in why the answer is the way it is. That’s why on the VMware Communities, you’ll see a little brain icon with “Guru” beside Eric’s handle. Eric is a prime example of the Roman philosopher Seneca’s maxim docendo discimus—by teaching we are learning. Eric is a working, hands-on VMware administrator and 25-year IT veteran, but with his work helping literally thousands on the VMware Communities and through his website, freelance writing, and blogging, Eric truly has become an expert educator. Eric was recently one of the first recipients of the VMware vExpert award for his contributions giving back to other virtualization users. This book, written by an expert educator and hands-on practitioner, takes you through the full lifecycle of a virtual infrastructure implementation, clearly lays out both the concepts and the steps required for someone new to virtualization, and can serve as a quick, clear review of best practices for the more experienced virtualization administrator. I wish you luck in your journey in virtualization. The first time you come into work in the morning and realize that one of your servers restarted during the night because of VMware’s High Availability feature, but neither your monitoring systems nor your end users noticed anything amiss, I encourage you to march into your boss’s office and ask for a promotion and a raise. You will have earned it.
