Virtual systems are computer-based simulations that run on software systems, that run on top hardware. They can offer a range of benefits to your business, including IT efficiency and cost savings.
Virtual machines can be used to test new software or to deploy Wikis and Jabber IM as well as create backup images of the current system to recover faster from a disaster. Virtual machines can be replicated and moved between physical servers for high availability configurations, which can reduce downtime.
The ability to virtualize multiple systems allows for significant reductions in server hardware, energy and maintenance costs. IT teams will spend less time on maintenance tasks, such the disadvantages of keeping paper records as the installation of software updates, since the entire virtual infrastructure is managed via a central platform. This increased efficiency allows your team to concentrate on strategic projects which will move your company forward.
Improved Data Security and 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 beneficial in cases where the original software manufacturer has removed support for an older version of code or has been shut down.
The type of hypervisor used in a virtual environment could determine the effectiveness of its management. A bare-metal hypervisor such as VMware vSphere, Microsoft Hyper-V or Oracle VM Virtualization gives you more control and independence from the host operating system. A hypervisor that is hosted, such as KVM, (built into Linux kernel) allows VM requests to the host OS, which can slow VM performance.
