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.

Microsoft Application Virtualization (App-V)

Microsoft Application Virtualization (App-V) enables enterprises to meet the needs of users and IT by empowering anywhere productivity and accelerated application deployment. App-V provides anywhere user access to applications that are dynamically available on any authorized PC without application installs. Virtual applications and user settings are preserved whether users are online or offline. App-V increases business agility through faster application deployment and updates with no user interruptions. It minimizes conflicts between applications, allowing enterprises to reduce application compatibility testing time. App-V together with Microsoft User State Virtualization (USV) provides users with a consistent experience and reliable access to applications and business data, no matter their location and connection to the Internet.
