What is server virtualization?
Server virtualization is a software architecture that allows more than one server operating system to run as a guest on a given physical server host. With the server software abstracted away from the physical machine in this way, the server becomes a "virtual machine," detached from the physical plane—though the server "thinks" it is running exclusively on the compute and memory resources. It’s actually running on a virtual imitation of the server hardware.

What is virtualization?
Virtualization uses software to create an abstraction layer over computer hardware that allows the hardware elements of a single computer—processors, memory, storage and more—to be divided into multiple virtual computers, commonly called virtual machines (VMs). Each VM runs its own operating system (OS) and behaves like an independent computer, even though it is running on just a portion of the actual underlying computer hardware.
How does virtualization work?
It abstracts hardware elements and functions (e.g., connections, switches, routers, etc.) and abstracts them into software running on a hypervisor. The network administrator can modify and control these elements without touching the underlying physical components, which dramatically simplifies network management.

What is the software called that separates the physical and virtual resources?
Software called hypervisors separate the physical resources from the virtual environments—the things that need those resources. Hypervisors can sit on top of an operating system (like on a laptop) or be installed directly onto hardware (like a server), which is how most enterprises virtualize. Hypervisors take your physical resources and divide them up so that virtual environments can use them.
What is NFV in networking?
Network functions virtualization (NFV) separates a network's key functions (like directory services, file sharing, and IP configuration) so they can be distributed among environments. Once software functions are independent of the physical machines they once lived on, specific functions can be packaged together into a new network and assigned to an environment. Virtualizing networks reduces the number of physical components—like switches, routers, servers, cables, and hubs—that are needed to create multiple, independent networks, and it’s particularly popular in the telecommunications industry.
Why is virtualization important in cloud computing?
Servers started being used more efficiently (or not at all), thereby reducing the costs associated with purchase, set up, cooling, and maintenance. Virtualization’s widespread applicability helped reduce vendor lock-in and made it the foundation of cloud computing.
What happens when a virtual machine is running?
When the virtual environment is running and a user or program issues an instruction that requires additional resources from the physical environment, the hypervisor relays the request to the physical system and caches the changes —which all happens at close to native speed (particularly if the request is sent through an open source hypervisor based on KVM, the Kernel-based Virtual Machine ).
When was virtualization first used?
Once you do that, the now empty servers could be reused for other tasks or retired altogether to reduce cooling and maintenance costs. While virtualization technology can be sourced back to the 1960s, it wasn’t widely adopted until the early 2000s.
