Virtualization and related technologies like hypervisors, which create virtual machines on a single hardware machine, and containers (also known as zones), which create virtual operating systems running on a single operating system, are a totally new area for many system administrators. Oracle® SolarisTM 10 System Virtualization Essentials provides an accessible introduction to computer virtualization, specifically the system virtualization technologies that use the Oracle Solaris or OpenSolaris operating systems. This accessible guide covers the key concepts system administrators need to understand and explains how to Use Dynamic Domains to maximize workload isolation on Sun SPARC systems Use Oracle VM Server for SPARC to deploy different Oracle Solaris 10 and OpenSolaris environments on SPARC CMT (chip multithreading) systems Use Oracle VM Server for x86 or xVM hypervisor to deploy a server with heterogeneous operating systems Use Oracle VM VirtualBox to develop and test software in heterogeneous environments Use Oracle Solaris Containers to maximize efficiency and scalability of workloads Use Oracle Solaris Containers to migrate Solaris 8 and Solaris 9 workloads to new hardware systems Mix virtualization technologies to maximize workload density Starting with a discussion of system virtualization in general terms—the needs of consolidation, the benefits of virtualization, and a description of the most common types of computer virtualization—this book also covers many of the concepts, features, and methods shared by many implementations of system virtualization. Oracle’s computer virtualization technologies that are directly related to the Oracle Solaris OS are described in detail along with a discussion of the factors that should be considered when choosing a virtualization technology. Finally, several examples of these technologies and an overview of virtualization management software are provided, as well as a history of virtualization.

Flexible and efficient, VMware ESX is the tool of choice for enterprise data centers looking to make the most of the latest virtualization methods. However, to date, no single manual provides users with a systematic way to understand and take full advantage of all its features and options.Novel Solutions for Every Level of the IT ChainVMware ESX Es

Securing virtual environments for VMware, Citrix, and Microsoft hypervisors Virtualization changes the playing field when it comes to security. There are new attack vectors, new operational patterns and complexity, and changes in IT architecture and deployment life cycles. What's more, the technologies, best practices, and strategies used for securing physical environments do not provide sufficient protection for virtual environments. This book includes step-by-step configurations for the security controls that come with the three leading hypervisor--VMware vSphere and ESXi, Microsoft Hyper-V on Windows Server 2008, and Citrix XenServer. Includes strategy for securely implementing network policies and integrating virtual networks into the existing physical infrastructure Discusses vSphere and Hyper-V native virtual switches as well as the Cisco Nexus 1000v and Open vSwitch switches Offers effective practices for securing virtual machines without creating additional operational overhead for administrators Contains methods for integrating virtualization into existing workflows and creating new policies and processes for change and configuration management so that virtualization can help make these critical operations processes more effective This must-have resource offers tips and tricks for improving disaster recovery and business continuity, security-specific scripts, and examples of how Virtual Desktop Infrastructure benefits security.

Microsoft Virtualization: Master Microsoft Server, Desktop, Application, and Presentation Virtualization serves a thorough reference for those considering a migration into the virtualized world. It provides the tools and explanations needed to create a fresh virtualization environment. Readers walk through step-by-step instructions on everything from building a Windows 2008 server to installing and configuring Hyper-V and App-V. The book begins with the basics of virtualization, including the role of virtualization in the changing landscape of the traditional data center and its benefits, and the strategies of virtualization. It presents the step-by-step process used to build a Windows 2008 server and the process of configuring and managing a Hyper-V infrastructure. Microsoft's approach to high availability and the combination of Microsoft tools to provide a very reliable and highly available virtualization infrastructure are discussed. The chapters also cover the migration of physical servers to virtual servers; the Dynamic Data Center concept; creating and publishing a virtual application within App-V; and desktop virtualization. This book was intended for seasoned system administrators and engineers who grew up in and still manage primarily a hardware-based server environment containing a large assortment of both newer and legacy applications. Covers Microsoft virtualization products completely, including Hyper-V Includes a special section on securing virtual infrastructure Gives hands-on instructions to help understand and implement Microsoft solutions

The purpose of this book is first to study cloud computing concepts, security concern in clouds and data centers, live migration and its importance for cloud computing, the role of firewalls in domains with particular focus on virtual machine (VM) migration and its security concerns. The book then tackles design, implementation of the frameworks and prepares test-beds for testing and evaluating VM migration procedures as well as firewall rule migration. The book demonstrates how cloud computing can produce an effective way of network management, especially from a security perspective.

Network Function Virtualization provides an architectural, vendor-neutral level overview of the issues surrounding the large levels of data storage and transmission requirements needed for today's companies, also enumerating the benefits of NFV for the enterprise. Drawing upon years of practical experience, and using numerous examples and an easy-to-understand framework, authors Tom Nadeau and Ken Gary discuss the relevancy of NFV and how it can be effectively used to create and deploy new services.
