Virtualization is the creation of a virtual (rather than actual) version of something, such as an operating system, a server, a storage device or network resources. Virtualization is software technology which uses a physical resource such as a server and divides it up into virtual resources called virtual machines (VM's).
 
Virtualization Advantages:
  • Server consolidation
  • Reduced power and cooling
  • Green computing
  • Ease of deployment and administration
  • High availability and disaster recovery
Server Virtualization
Hardware Virtualization uses software to create a Virtual Machine (VM) that emulates a physical computer. This creates a separate OS environment that is logically isolated from the host server. By providing multiple VMs at once, this approach allows several operating systems to run simultaneously on a single physical machine.
Rather than paying for many under-utilized server machines, each dedicated to a specific workload, server virtualization allows those workloads to be consolidated onto a smaller number of more fully-used machines.
 
Desktop Virtualization
Microsoft’s Desktop Virtualization solutions help companies to reduce their total cost of ownership, increase business agility and continuity, enable anywhere access, and improve security and compliance. For companies new to desktop virtualization, deploying Microsoft Application Virtualization as a first step can provide immediate cost savings.
 
Virtualization Management
Virtual machines are actual computers with real workloads, Managing them just like we manage our physical systems is imperative. By using System Center, a comprehensive set of integrated management tools, you can keep complexity at a minimum and streamline operations. A common management environment reduces training, ensures uniform policy application and simplifies maintenance by leveraging your existing software, personnel, and most importantly, your existing IT management process.
 
Popular virtualization products include:
  • VMware
  • Microsoft Hyper-V
Microsoft Hyper-V
Microsoft Windows Server 2008 R2, the most advanced Windows Server operating system yet, increases server infrastructure flexibility while saving time and reducing costs. With Windows Server 2008 R2 you can develop, deliver, and manage rich user experiences and applications, provide a highly secure network infrastructure, and increase technological efficiency and value within your organization.
Everything needed to support server virtualization is available as an integral feature of the operating system as Windows Server 2008 R2 Hyper-V. With Hyper-V as a role, plus flexible licensing policies, it's now easier than ever to take advantage of the cost savings of virtualization through Windows Server 2008 R2.
Windows Server Hyper-V R2, the next-generation hypervisor-based server virtualization technology, allows you to make the best use of your server hardware investments by consolidating multiple server roles as separate virtual machines (VMs) running on a single physical machine. With Hyper-V R2 you can also efficiently run multiple different operating systems Windows, Linux, and others in parallel, on a single server, and fully leverage the power of x64 computing. And because Hyper-V R2 uses the same VHD format as Hyper-V as well as Virtual Server 2005 R2, migrating workloads from this earlier technology is relatively straightforward.
 
Vmware
Transform your Business with Virtualization
Improve the efficiency and availability of IT resources and applications through virtualization. Start by eliminating the old one server, one application model and run multiple virtual machines on each physical machine. Free your IT admins from spending so much time managing servers rather than innovating. About 70% of a typical IT budget in a non-virtualized datacenter goes towards just maintaining the existing infrastructure, with little left for innovation.
An automated datacenter built on the production-proven VMware virtualization platform lets you respond to market dynamics faster and more efficiently than ever before. VMware vSphere delivers resources, applications an even servers as when and where they're needed. VMware customers typically save 50-70% on overall IT costs by consolidating their resource pools and delivering highly available machines with VMware vSphere.
  • Run multiple operating systems on a single computer including Windows, Linux and more.
  • Let your Mac run Windows creating a virtual PC environment for all your Windows applications.
  • Reduce capital costs by increasing energy efficiency and requiring less hardware while increasing your server to admin ratio
  • Ensure your enterprise applications perform with the highest availability and performance
  • Build up business continuity through improved disaster recovery solutions and deliver high availability throughout the datacenter
  • Improve enterprise desktop management & control with faster deployment of desktops and fewer support calls due to application conflicts
