Virtual systems are software-based emulations computer systems that operate on the top of physical hardware. They can provide many advantages to your company such as IT efficiency and cost savings.
Virtual machines are a great way to test new software, test Wikis or Jabber IM services, and even create backup images of your current system for faster recovery in the event of a disaster. Virtual machines can be replicated, or migrated to other physical servers with high availability configurations, reducing downtime.
The capability to virtualize multiple systems allows for significant reductions in server equipment, energy and maintenance costs. IT IT infrastructure: the backbone of modern enterprises personnel will spend less time performing maintenance tasks, like updating software because the virtual infrastructure is controlled by a central platform. This increases efficiency enables your team to concentrate on strategic initiatives that will propel your business 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 when the original software manufacturer has stopped supporting an older piece of code, or the developer has gone out of business.
The type of hypervisor used in a virtualized environment can determine the effectiveness of its management. A bare-metal virtualization based hypervisor such as VMware vSphere, Microsoft Hyper-V or Oracle VM Virtualization offers greater control and autonomy with the host operating system. A hypervisor that is hosted, such as KVM, (built into Linux kernel), passes VM requests to the host OS, which can slow VM performance.
