Virtual systems are software-based simulations of computer systems, that run on top hardware. They can offer a range of advantages to your business such as IT efficiency and cost savings.
Virtual machines can be used to test new software or to deploy Wikis and Jabber IM, as well streamline tasks with robotic process automation as to create backup images of the current system in order to recover faster from an event. Virtual machines can also be replicated and migrated between physical servers for high-availability configurations to reduce downtime.
The capability to virtualize multiple systems enables significant reductions in server energy, hardware and maintenance costs. IT teams can spend less time on maintenance tasks, such as deploying software updates because the entire virtual infrastructure is controlled by a central platform. This increased efficiency will allow your team to concentrate on strategic projects that move your company 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 when the original software manufacturer has removed support for an older version of code, or the developer has been shut down.
The type of hypervisor used in a virtual environment could determine the effectiveness of its management. A hypervisor based on bare metal, like VMware vSphere or Microsoft Hyper-V, provides more control and autonomy from the host operating system. On the other hand, a hosted hypervisor like KVM (built in the Linux kernel) is able to pass VM requests through the host OS to process, which can slow down VM performance.
