Server Virtualization Overview
What is Server Virtualization Software?
The concept of virtualization generally refers to separating the logical from the physical. For servers in a datacenter, the norm is for one machine to run a single operating system. Virtualization allows multiple operating systems to be run completely independently on a single machine. Virtualization uses specialized software called a Hypervisor that encapsulates a guest version of the operating system and emulates a range of hardware resources like server CPU, memory, hard disk and other resources so that these resources can be shared across multiple virtual machines. In this way multiple operating systems can be run on a single machine.
The benefits of this approach are clear: reduced need, physical hardware systems; lower maintenance costs, and subsequent reduced power and cooling requirements.
The recent emergence of Docker has given an impetus to an alternative to server virtualization called containerization. The difference between these two approaches is that containerization achieves far greater efficiency by eliminating the hypervisor and its multiple virtual machines. Each application shares a single instance of the operating system and runs on the “bare metal” of the server.
Server Virtualization Features & CapabilitiesServer virtualization products have a large number of potential features, but among the most common are:
- Automation of virtual machine provisioning
- Ability to centrally control and optimize the virtual machine environment
- Ability to backup running virtual machines without interrupting service
- Ability to migrate live virtual machines between hosts during scheduled maintenance
- Hypervisor-level security, including antivirus and anti-malware
