Chapter 2: Windows Server virtualization
Introduction
Today's datacenter is a complex ecosystem where different kinds of servers, operating systems, and applications interact with a wide variety of desktop and mobile clients. IT departments are under increasing pressure to manage and support this assortment of mission-critical technologies while controlling costs and maintaining reliability and security. Deploying server virtualization technology--moving disparate servers to virtual machines (VMs) in a centrally managed environment --is an increasingly popular option for addressing these challenges.
Virtualization helps reduce IT costs, centralize network management, increase network security, improve server availability, and to increase hardware utilization.
Microsoft® Windows Server® 2008 includes Windows Server virtualization (WSv), a powerful virtualization and network management technology that enables businesses to take advantage of virtualization's benefits without buying third-party software. Virtual machines provide unprecedented abilities to leverage available hardware, Microsoft and its partners provide one-stop support for interoperability issues with multiple operating systems (Windows, Linux, and Xen-enabled Linux), and IT departments can manage both virtual and physical resources using flexible and powerful tools.
This chapter introduces Windows Server virtualization as a key component of the Microsoft desktop-to-datacenter virtualization strategy. It shows how new and enhanced features in Windows Server virtualization help relieve enterprise customer pain points in common scenarios: server consolidation, business continuity/disaster recovery management, testing and development, and the dynamic data center. It also highlights how these benefits scale to meet the unique needs of small and branch offices.
Virtualization is a widely adopted solution. 80 percent of organizations are using or evaluating virtualization and seeing its advantages for server consolidation, centralized management, and other cost-saving uses. Because these benefits decrease cost, companies want to virtualize more demanding workloads. They want more powerful and flexible virtualization solutions that are better integrated with their management tools. Wide adoption of 64-bit, multi-processor, multi-core servers spurs demand for virtual machines that are better able to take advantage of more robust processing power.
In response to these developments, Microsoft created Windows Server virtualization, a next-generation, 64-bit virtualization technology facilitating agility and seamless management of both physical and virtual components. It provides a platform enabling flexibility through dynamic and reliable virtualization capabilities.
