Virtual systems are software-based emulations computer systems that operate on the top of physical hardware. They offer a number of benefits for your business including IT efficiency, cost savings and security.
Virtual machines can be used to test new software or deploy Wikis and Jabber IM, as well as to create backup images of the system currently in order to get back up and running faster following the aftermath of a catastrophe. Virtual machines can be replicated, or migrated to other physical servers in high availability configurations, thus reducing downtime.
The capability to virtualize multiple systems results in significant reduction in server energy, hardware and maintenance costs. IT personnel will be less busy with maintenance tasks, such as updating software, because the virtual infrastructure is managed by a central platform. This increases efficiency enables your team to concentrate on strategic projects that 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 particularly useful in situations where the original software manufacturer has stopped supporting an older piece of code or the developer has been shut down.
The type of hypervisor that is used in a virtual environment could make or break the effectiveness of its management. A bare-metal hypervisor such as VMware vSphere, Microsoft Hyper-V or Oracle VM Virtualization allows for 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 affect VM performance.
