HYPER V

Secure Track > Solutions > HYPER V

Hyper-V is Windows Server virtualization platform that is included as a role of Windows Server. Hyper-V does not use its host operating system to run the virtual machines, but does this via a so-called hypervisor. A hypervisor sits between the physical hardware and the host operating system and enables the physical hardware to be virtualized and therefore can run multiple operating systems. This technique makes it possible for physical hardware to be used very efficiently.


HIGHER PERFORMANCE:

Hyper-V does not use its host operating system to run the virtual machines, but does this via a so-called hyper visor. A hyper visor sits between the physical hardware and the host operating system and enables the physical hardware to be virtualized and therefore can run multiple operating systems. This technique makes it possible for physical hardware to be used very efficiently. One of the biggest advantages is that the resources (CPU, memory and disk) can easily be added to different virtual machines. Another additional advantage is that Hyper-V also supports 64 bit systems and therefore supports more than 4GB of memory.

SECURITY:

Hyper-V uses the individual virtual machines and their associated disk partitions to store device drivers. As a result, drivers can run independently for each virtual machine. The compartmentalized nature of Hyper-V gives it a layer of security that monolithic hypervisors like VMware’s vSphere lack. By dividing its virtual machines across drive partitions, hackers need to crack open each virtual machine in Hyper-V rather than simply latching onto a single hypervisor via its API.

MORE STABLE:

Increased stability is another benefit of the compartmentalization that comes with Hyper-V. With each virtual machines’ device drivers running at the virtual level rather than the hypervisor level, if a virtual machine becomes unstable, it’s only going to take down only the effected machine rather than the whole virtual platform.

REPLICATION:

Hyper-V Replica is a much lauded new feature built into Hyper-V in Windows Server 2012. It means you can easily clone servers across a WAN or secure VPN and have them spare in case of a VM outage. This is a feature that was once only available to large and well-resourced companies to small and medium businesses.


HYPER-V IS WINDOWS BASED:

As a virtual platform built in Windows, its familiar interface, functions and layout mean it is much easier to use if you are used to the working in Windows environment. This is a great benefit if you are the informal admin for your office or if you just prefer working with Windows.

HYPER-V IS INCLUDED IN SERVER 2012

It comes as a freebie in Windows Server 2012 and who doesn’t like a freebie, especially as many IT departments are under pressure to cut down their costs. On top of this the included features in Hyper-V are comparable to what you find in the more expensive versions of other hypervisor platforms.
