Virtual systems are software-based emulations of computer systems that run on top of physical hardware. They can provide many benefits to your business such as IT efficiency and cost savings.

Virtual machines are great for testing new software, deploy Wikis or Jabber IM services and create backup images of your current system for faster recovery in the event of a natural disaster. VMs can also be replicated and transferred between physical servers for high availability configurations that minimize downtime.

Virtualizing multiple systems can reduce server hardware, maintenance and energy costs. The IT team can be less busy with maintenance tasks, such as updating software, since the virtual infrastructure is managed by an integrated platform. This efficiency boost can aid your team in focusing on projects that will propel your business forward.

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 the event when the creator of an older piece of software is no longer in business or is not supported anymore by the original equipment manufacturer.

The type of hypervisor that is used in a virtualized environment could determine the success or failure of its management. A bare-metal virtualization hypervisor such as VMware vSphere, Microsoft Hyper-V or Oracle VM Virtualization allows for greater control and autonomy over the host operating system. On the other the other hand, a hosted hypervisor like KVM (built into the Linux kernel) is able to pass VM requests through the host OS to process them, which can slow down VM performance.
