Virtualization Essentials

Learn virtualization skills by building your own virtual machine

Virtualization Essentials, Second Edition provides new and aspiring IT professionals with immersive training in working with virtualization environments. Clear, straightforward discussion simplifies complex concepts, and the hands-on tutorial approach helps you quickly get up to speed on the fundamentals. You'll begin by learning what virtualization is and how it works within the computing environment, then you'll dive right into building your own virtual machine. You'll learn how to set up the CPU, memory, storage, networking, and more as you master the skills that put you in-demand on the job market. Each chapter focuses on a specific goal, and concludes with review questions that test your understanding as well as suggested exercises that help you reinforce what you've learned.

As more and more companies are leveraging virtualization, it's imperative that IT professionals have the skills and knowledge to interface with virtualization-centric infrastructures. This book takes a learning-by-doing approach to give you hands-on training and a core understanding of virtualization.

  • Understand how virtualization works
  • Create a virtual machine by scratch and migration
  • Configure and manage basic components and supporting devices
  • Develop the necessary skill set to work in today's virtual world

Virtualization was initially used to build test labs, but its use has expanded to become best practice for a tremendous variety of IT solutions including high availability, business continuity, dynamic IT, and more. Cloud computing and DevOps rely on virtualization technologies, and the exponential spread of these and similar applications make virtualization proficiency a major value-add for any IT professional. Virtualization Essentials, Second Edition provides accessible, user-friendly, informative virtualization training for the forward-looking pro.

Virtualization Essentials


We live in an exciting time. The information age is exploding around us, giving us access to dizzying amounts of data the instant it becomes available. Smart phones and tablets provide an untethered experience that offers streaming video, audio, and other media formats to just about any place on the planet. Even people who are not "computer literate" use Facebook to catch up with friends and family, use Google to research a new restaurant choice and print directions to get there, or Tweet their reactions once they have sampled the fare. The budding Internet-of-things will only catalyze this data eruption. The infrastructure supporting these services is also growing exponentially, and the technology that facilitates this rapid growth is virtualization.

On one hand, virtualization is nothing more than an increasingly efficient use of existing resources that delivers huge cost savings in a brief amount of time. On the other, virtualization also offers organizations new models of application deployment for greater uptime to meet user expectations, modular packages to provide new services in minutes instead of weeks, and advanced features that bring automatic load balancing, scalability without downtime, self-healing, self-service provisioning, and many other capabilities to support business-critical applications that improve on traditional architecture. Large companies have been using this technology for 10 to 15 years, while smaller and medium-sized businesses are just getting there now. Some of them might miss the movement altogether and jump directly to cloud computing, the next evolution of application deployment. Virtualization is the foundation for cloud computing as well.

This quantum change in our world echoes similar trends from our recent history as electrical power and telephony capabilities spread and then changed our day-to-day lives. During those periods, whole industries sprang up out of nothing, providing employment and opportunity to people who had the foresight and chutzpah to seize the moment. That same spirit and opportunity is available today as this area is still being defined and created right before our eyes. If not virtualization vendors, there are hardware partners who provide servers, networking vendors for connectivity, storage partners for data storage, and everyone provides services. Software vendors are designing and deploying new applications specifically for these new architectures. Third parties are creating tools to monitor and manage these applications and infrastructure areas. As cloud computing begins to become the de facto model for development, deployment, and maintaining application services, this area will expand even further.

The first generation of virtualization specialists acquired their knowledge out of necessity: They were server administrators who needed to understand the new infrastructure being deployed in their data centers. Along the way, they picked up some networking knowledge to manage the virtual networks, storage knowledge to connect to storage arrays, and application information to better interface with the application teams. Few people have experience in all of those areas. Whether you have some virtualization experience or none at all, this text will give you the foundation to understand what virtualization is, why it is a crucial portion of today's and tomorrow's information technology infrastructure, and the opportunity to explore and experience one of the most exciting and fastest growing topics in technology today.

Good reading and happy virtualizing!
