Virtual systems are software-based versions of computer systems that operate on the top of physical hardware. They provide a range of advantages to your business, such as IT efficiency as well as cost savings and security.
Virtual machines are ideal for testing new software, implement Wikis or Jabber IM services and also create backup images of your current system for faster recovery in case of disaster. Virtual machines can be replicated or transferred to other physical servers in high availability configurations, which can reduce downtime.
Virtualizing multiple systems can cut down on server hardware, maintenance and energy costs. IT staff can spend less time on maintenance tasks, like updating software, because the virtual infrastructure is controlled by an integrated platform. This efficiency boost can help your team focus on strategic projects that can propel 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 especially beneficial in cases where the original software manufacturer has stopped supporting an older piece of code or the developer has been shut down.
The type of hypervisor used in a virtualized system can affect the management of the virtualized environment. A bare-metal hypervisor such as VMware vSphere, Microsoft Hyper-V or Oracle VM Virtualization gives you more control and autonomy over the host operating system. A hosted hypervisor, such as KVM, (built into Linux kernel) is able to pass VM requests to the host OS which can affect VM performance.
