Hyper-V 2012 R2 is Microsoft’s virtualization platform, or ‘hypervisor’, which enables administrators to make better use of their hardware by virtualizing multiple operating systems to run off the same physical server simultaneously.
With Hyper V, you can virtualize server operating systems in the data center or Windows phone environments on your desktop and most everything in between. It is also a great tool for developers that want a safe sandbox to test software.
Benefits of Hyper-V:
1. Stretching Your Hardware Dollar Further
Hardware continues to accelerate in almost every performance metric. Each year, new CPUs can process more data in the same amount of time, memory chips can hold more data for the same amount of money, and hard drive densities increase. On the other side, the demands of the most common software applications have not increased at the same pace. Hyper-V allows you to make much better use of the hardware that you’ve purchased by consolidating more computing jobs on less hardware without fear of compatibility issues.
2. Reduced Energy Demands
With the increasing popularity of “green” initiatives to reduce energy consumption, consolidation of systems onto fewer physical systems translates directly into a lower energy footprint, both in direct power and in auxiliary power, such as lighting and cooling. A smaller ecological footprint also means a smaller utility bill.
3. Enhanced Portability for Server Applications
Hyper-V also provides a great deal of portability to your server-based applications. They can be easily moved to new hardware with little or no downtime. Workloads can be rebalanced if hardware becomes overloaded, or they can be quickly recovered on another system if hardware fails. The VHDX file format that Hyper-V uses to hold virtual machine data can be mounted by any current Windows operating system so you can recover data quickly and easily.
4. Rapid Deployment of Server Environments
With a physical infrastructure already in place, new operating system environments can be deployed from templates in a few minutes, drastically reducing the time necessary to provision and deploy a new Windows Server or Linux installation.
5. Built-In Lab Environments
With the rapid provisioning and isolation features that are natural to Hyper-V, you can quickly design and deploy test and sandbox environments quickly. Disposing of them once testing has been completed is even quicker.
6. Reduced Management Effort
All virtual machines running on a host or cluster can be viewed from a single pane using existing tools. For larger installations, management tools are available to monitor virtual machines across the entire data center. PowerShell and other tools enable mass simultaneous management of these systems.
7. Licensing Savings
Of all currently available virtualization platforms, Hyper-V Server is one of the few that has no price tag, regardless of the feature set. All features of Hyper-V are available in even the free edition, including failover clustering, multi-path I/O, and no artificial limits on CPU or memory utilization.
