Virtual systems are computer-based simulations that run on software systems, that run on top hardware. They can offer a range of advantages to your business that include IT efficiency and cost savings.
Virtual machines can be used to test new software or deploy Wikis and Jabber IM, as well as to create backup images of the current system to be able to recover faster after an event. Virtual machines can be replicated or migrated to other physical servers in high availability configurations, which can reduce downtime.
Virtualizing multiple systems could reduce server hardware, maintenance and energy costs. IT teams are able to spend less time on maintenance tasks such as updating software because the entire virtual infrastructure is managed by a central platform. This improved efficiency allows your team to concentrate on strategic projects which will improve the performance of your business.
Improved Data Security & Disaster Recovery
VMs are hardware-independent, meaning that they can be moved from one physical server to another just as easily as moving files on your desktop or laptop. This is particularly useful in situations where the original software manufacturer has removed support for an older version of code or has been shut down.
The type of hypervisor that is used in a virtual environment could determine the efficiency of its management. A hypervisor that is bare-metal, such as VMware vSphere or Microsoft Hyper-V, provides more control and independence from the host operating system. A hypervisor hosted on a host, like KVM, (built into Linux kernel), passes VM requests to the host OS which may slow VM performance.
