This book focuses on the core question of the necessary architectural support provided by hardware to efficiently run virtual machines, and of the corresponding design of the hypervisors that run them. Virtualization is still possible when the instruction set architecture lacks such support, but the hypervisor remains more complex and must rely on additional techniques. Despite the focus on architectural support in current architectures, some historical perspective is necessary to appropriately frame the problem. The first half of the book provides the historical perspective of the theoretical framework developed four decades ago by Popek and Goldberg. It also describes earlier systems that enabled virtualization despite the lack of architectural support in hardware. As is often the case, theory defines a necessary—but not sufficient—set of features, and modern architectures are the result of the combination of the theoretical framework with insights derived from practical systems. The second half of the book describes state-of-the-art support for virtualization in both x86-64 and ARM processors. This book includes an in-depth description of the CPU, memory, and I/O virtualization of these two processor architectures, as well as case studies on the Linux/KVM, VMware, and Xen hypervisors. It concludes with a performance comparison of virtualization on current-generation x86- and ARM-based systems across multiple hypervisors.
What exactly is virtualization? As this concise book explains, virtualization is a smorgasbord of technologies that offer organizations many advantages, whether you're managing extremely large stores of rapidly changing data, scaling out an application, or harnessing huge amounts of computational power. With this guide, you get an overview of the five main types of virtualization technology, along with information on security, management, and modern use cases. Topics include: Access virtualization—Allows access to any application from any device Application virtualization—Enables applications to run on many different operating systems and hardware platforms Processing virtualization—Makes one system seem like many, or many seem like one Network virtualization—Presents an artificial view of the network that differs from the physical reality Storage virtualization—Allows many systems to share the same storage devices, enables concealing the location of storage systems, and more
Everything you wanted to know about virtualization but were afraid to ask. This book would be more appropriately titled "The Encyclopedia of Virtualization." It covers just about every aspect of Virtualization someone in IT would be concerned about, from high-level overviews of the different technologies that might be appropriate for upper management, to a very nice series of "hands on" chapters that walk you through experimenting with several of the free virtualization options. Whether you need a quick primer on virtualization so you can talk shop with those with more detailed knowledge, or want to get a sense of the benefits of the different technologies and how they fit into the big picture of the data center, this book is an invaluable resource. It gives you the vocabulary and understanding of how all the pieces fit together than websites and technical manuals often miss. A must-buy comprehensive introduction. This book assumes you know nothing about Virtualization and quickly reviews some of the buzzwords that frequently get thrown around (hypervisor, bare metal, ...). It provides a detailed introduction to key topics including Server Virtualization, Software Options, and managing a Virtualization Project. For business analysts, there is an informative chapter on cost-benefit analysis and several chapters on best practices and pitfalls. With energy costs becoming a major factor in IT budgets, Virtualization will become even more widespread in the future. This is the best introductory book for practitioners and delivers a great overview of the complex world of virtualization, it provides a broad and comprehensive view of the complex world of virtualization, covering alarge amount of territory. All of the major virtualization technologies are discussed, along with the various drivers for implementing virtualization, and how to manage migrating to a virtualized computing environment. What makes this book stand out from most other resources on the topic is its tone. You're helpfully guided through the issues and tradeoffs in making a number of decisions on the what, where, when and how of virtualization. This is extremely helpful for an IT manager who needs to come up to speed in a short period of time. This book is a Well-written technical overview with a great business focus, 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 allowingfor interrelated topics to be introduced in the proper logically dependent sequence. Chapters such as "Common Terminology," "Companies Using Virtualization," "Why Virtualized Technology?," "Benefits of Virtualization," "Virtualization Technologies," "Comparison between Technologies," "Accomplishing Virtualization" and "Managing a Virtualized Environment" are precisely what CIOs, IT managers, and technologists need to know.
The earliest computers were very expensive, single-task machines devoted to running a single program at a time. Each program loaded from a stack of punch cards, and ran its course without interacting with the outside world. Running payroll, for example, meant that the system was unavailable for any other function until the payroll was complete, the checks printed, the books balanced, and updates written to new punch cards and stored for the next run. This very expensive machine spent most of the time waiting on the peripherals, the printer, the card reader, and the card punch. This book is different from others because in this book: · You will learn cloud distribution models · You will learn about emerging cloud service categories · You will learn about skills of a · Cloud specialist · Learn Cloud Computing, Planning, Technologies, Architecture, · Infrastructure, Cloud Models, More!

The IT sector is full of hype. But once in a while there is a genuine inflection point, a moment at which the way of doing things fundamentally changes due to the introduction of new technologies. The rise of cloud computing is just such an inflection point. Cloud computing is the next stage of the Internet computing model, one in which organizations will consume services, not technologies. These services will be ready to run, available outside the office walls, and be paid for on the basis of usage, just like water or electricity. As the cloud and services model matures, not only will businesses be able to solve old problems more inexpensively and rapidly, they will also be able to address new challenges that were previously out of reach. Cloud computing promises a more flexible 'services' model for IT systems that puts the business unit or end user at the center of the process. In this way, both the IT organization and the business itself become more agile. At the same time, cloud computing promises to reduce the delivered cost of IT through a greater degree of resource utilization, automation, and self service. This will not happen overnight. It will not be next year, nor even within a year or two. But as time passes, more and more companies will find themselves in a position to be able to source services wherever they like: inside the organization or from any provider, whether it be Google, IBM, HP, EMC, Cisco, Microsoft, Amazon, T-Systems or any other cloud computing vendor. This book is a comprehensive introduction to cloud computing and its most prominent enabling technology: virtualization. In the first part, you are guided through the visions, concept and models behind cloud computing. You will learn how your organization can profit from cloud-enabling technologies and how you can incorporate them in your IT infrastructure. Part II of this book consists of 'Industry Outlooks': in depth articles from industry experts. Part III offers a series of useful case stories, covering a broad diversity of virtualization and cloud-related issues. Further to the development of this book, the development team that is responsible for the content of this book, has developed a certification program on Cloud computing, the Cloud Certification Program.
