Virtual systems are software-based emulations of computer systems that run on top of physical hardware. They can provide many benefits to your business including IT efficiency and cost savings.
Virtual machines can be used to test new software, or deploy Wikis and Jabber IM, and even create backup images of the system currently in order to recover faster from an incident. Virtual machines can be replicated, and even migrated between physical servers to create high-availability configurations to reduce downtime.
The capability to virtualize multiple systems enables significant reductions in server energy, hardware and maintenance costs. IT personnel will spend less time performing maintenance tasks, like updating software because the virtual infrastructure is controlled by a central platform. This improved efficiency allows your team to focus on strategic projects which 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 especially useful in cases where the original software manufacturer has discontinued support for an older piece of software or the developer has been shut down.
The type of hypervisor used in a virtualized environment can 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 independence from the host operating system. A hosted hypervisor, such as KVM, (built into Linux kernel) can forward VM requests to the host OS which can affect VM performance.
