Book SynopsisVirtualization 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.Table of ContentsForeword xvii Introduction 1 Part I: Getting Started with a Virtualization Project 7 Chapter 1: Wrapping Your Head around Virtualization 9 Chapter 2: Making a Business Case for Virtualization 33 Chapter 3: Understanding Virtualization: Technologies and Applications 49 Chapter 4: Peeking at the Future of Virtualization 83 Part II: Server Virtualization 99 Chapter 5: Deciding Whether Server Virtualization Is Right for You 101 Chapter 6: Performing a Server Virtualization Cost-Benefit Analysis 111 Chapter 7: Managing a Virtualization Project 129 Chapter 8: Choosing Hardware for Your Server Virtualization Project 159 Part III: Server Virtualization Software Options 187 Chapter 9: Migrating to Your New Virtualized Environment 189 Chapter 10: Managing Your Virtualized Environment 209 Chapter 11: Creating a Virtualized Storage Environment 221 Part IV: Implementing Virtualization 243 Chapter 12: Implementing VMware Server 245 Chapter 13: Implementing Fedora Virtualization 267 Chapter 14: Implementing XenExpress 291 Part V: The Part of Tens 319 Chapter 15: Ten Steps to Your First Virtualization Project 321 Chapter 16: Ten Virtualization Pitfalls to Avoid 329 Chapter 17: Ten Great Resources on Virtualization 335 Index 341

Book SynopsisIn an era of ubiquitous clouds, virtualization, mobility, and the Internet of Things, information and resources must be accessible anytime, from anywhere. Connectivity to devices and workloads must be seamless even when people move: location must be fully independent of device identity. The LISP protocol makes all this possible. LISP is address-family agnostic, so it can encapsulate any protocol within another, and route across virtually any network. LISP applications include very-large-scale virtualization for WANs and multi-tenant data centers; host mobility and location services across data centers; advanced mobile networks; ad-hoc networks; IPv6 enablement, seamless site multi-homing; workload mobility; cellular mobility; multicast and traffic engineering, and more. The LISP Network is the first comprehensive, in-depth guide to LISP concepts, architecture, techniques, and applications. Co-authored by LISP co-creator Dino Farinacci and two pioneering developers of Cisco's LISP implementation, this guide will help you plan and implement LISP in any data center, WAN edge, or service provider core network. Largely implementation-agnostic, this book offers actionable answers to questions such as: What problems does LISP address, and how does it address them? How does LISP work? What are LISP's applications, and how do you architect LISP solutions for each application? How does LISP fit with SDN, IoT, and IPv6? What is LISP's future? The LISP Network concludes with detailed deployment case studies of several LISP applications, each drawn from the authors' pioneering experience.Table of Contents 1.

Book Synopsis DESCRIPTION In the cloud computing model, a cluster of physical computers hosts an environment that provides shared services (public and private) and offers the flexibility to easily add, remove, and expand virtual servers and applications. OpenStack is an open source framework that can be installed on individual physical servers to a cloud platform and enables the building of custom infrastructure (IaaS), platform (PaaS), and software (SaaS) services without the high cost and vendor lock-in associated with proprietary cloud platforms. OpenStack in Action offers real world use cases and step-by-step instructions to develop cloud platforms from inception to deployment. It explains the design of both the physical hardware cluster and the infrastructure services needed to create a custom cloud platform. It shows how to select and set up virtual and physical servers, implement software-defined networking, and the myriad other technical details required to design, deploy, and operate an OpenStack cloud in an enterprise. It also discusses the cloud operation techniques needed to establish security practices, access control, efficient scalability, and day-to-day DevOps practices. RETAIL SELLING POINTS Real world examples Thorough step-by-step instruction Shows how to harness the power of OpenStack AUDIENCE The book is perfect systems administrators, developers, and architects interested in the design, construction, and operation of clouds using OpenStack. No prior experience with OpenStack or cloud development required. ABOUT THE TECHNOLOGY OpenStack as a framework for managing, designing, defining, and utilizing cloud resources. There are over 13k OpenStack contributors in over 131 countries. Every major IT vendor has some form of OpenStack representation, even those with directly competing products.

Book SynopsisThe idea behind Docker is simple. Create a tiny virtual environment called a container that holds just your application and its dependencies. The Docker engine uses the host operating system to keep track of your containers. Applications running inside containers share resources, making their footprints small. They are easy to install, manage, and remove. Docker in Action, Second Edition teaches you to create, deploy, and manage applications hosted in Docker containers running on Linux. Fully updated, with four new chapters and revised best practices and examples, this second edition begins with a clear explanation of the Docker model. Then, you go hands-on with packaging applications, testing, installing, running programs securely, and deploying them across a cluster of hosts. With examples showing how Docker benefits the whole dev lifecycle, you'll discover techniques for everything from dev-and-test machines to full-scale cloud deployments.Trade Review'Jeff and Stephen took their battle-hardened experience and updated this already great book with new details and examples.'

Book SynopsisThis book analyzes a new phenomenon in civilization: the transformation of the current "Information Wave" into virtual civilization. In the 21st century, the "real-space" of the world civilization, due to the massive, network-intensive use of computers world-wide, gained the virtual space known as cyberspace. Cyberspace is a product of information technology exemplified by the Internet as the world system of information highway(s) [INFOSTRADA(S)] which forms a digital space containing all sorts of files and communication exchanges practiced in online and real-time modes. For the first time in 6,000 years of human civilization, society has become a quantum society, which can be real and virtual at the same time. The virtual society is invisible for those who do not use computer networks. Even for those who do use them, cyberspace access requires some sort of commercial transactions-oriented activities (ex. on Amazon or eBay and others), searching on Google or Yahoo or communicating as a member of one of social networks, e.g.. Facebook, Twitter, LinkedIn, and others.
