Virtualization is a term that refers to the abstraction of computer resources. It is commonly defined as a technology that introduces a software abstraction layer between the hardware, operating system and applications running on top of it. More recently, virtualization at all levels (system, storage, and network) became important again as a way to improve system security, reliability and availability, reduce costs, and provide greater flexibility. Virtualization was first developed in 1960’s by IBM Corporation, which partition large mainframe computer into several logical instances and to run on single physical mainframe hardware as the host. Two primary benefits offered by any virtualization technology are ( Sahoo, J., Mohapatra, S., & Lath, R. 2010 ). (i)Resource sharing - Unlike in non-virtualized environment where all the resources are dedicated to the running programs, in virtualized environment the VMs shares the physical resources such as memory, disk and network devices of the underlying host. (ii)Isolation - One of the key issues in virtualization provides isolation between virtual machines that are running on the same physical hardware. Programs running in one virtual machine cannot see programs running in another virtual machine. Learn more in: An Evolutionary Approach for Load Balancing in Cloud Computing

Is the consolidation of operating systems deployed with several physical servers into one physical server for the better utilization of computer infrastructures (resources), that is, enables their simultaneous use in different systems. Computer networks, programs, and operating systems are virtualized. Learn more in: Application of Cloud Computing in Companies

Virtualization is a key technology to create cloud computing platform. Unused resources can be effectively utilized, based on the requirement resources can be scaled using this technology compared to physical resource scaling. Entire existing OS along with all its application also can be moved to a virtual machine or vice versa also possible. Virtualization is simulating hardware and/or software to run on top of hardware and/or software. Learn more in: Security Issues in Cloud Computing

A form of abstraction that provides location- and technology-transparent access of resources to the consumer. It decouples the tight connections between providers and consumers of resources, thus allowing sharing of the same resources by multiple users as needs arise.

The passage from the actual state of being to the virtual. The actual is a manifest state that tries to solve a problem in a creative manner, but when this creative solution is questioned again it is re-articulated and virtualized. It is a process of dematerialization but at the same time of thinking, inspiring, reasoning, and connecting different (and often non-obvious) actors.

In computing, virtualization refers to the act of creating virtual resources, including virtual computer hardware platforms, storage devices, and computer network resources. Virtualization is as old as computer science but became very popular with the hardware improvement in particular in chipset industry and the development of Linux. The different virtualization technologies are heavily used by the cloud computing industry. Virtualization is also a key driver for the development of the web technologies especially on distributed storage, big data, machine learning, and artificial intelligence.

Virtualization is the process of creating a software based (or virtual) representation of something rather than a physical one. Virtualization can apply to applications, servers, storage and networks and is the single most effective way to reduce IT expenses while boosting efficiency and agility for all size businesses (Vmware, 2016 AU129: The in-text citation "Vmware, 2016" is not in the reference list.

Virtualization one of the key technology used in cloud computing. Virtualization allows multiple OS to run on a single physical machine. All computing resources are provided to the client through Virtualization. It increases the resource utilization because same hardware can be used by multiple user. One of the important features of the Virtualization is the live migration, a process of transferring the virtual machine from one physical machine to another physical machine. Since the load on the virtual machine can be changed dynamically, so there is a possibility when the current physical machine is unable to fulfill the resource requirement of the virtual machine. This problem can be addressed either by adding the extra resources to the physical machine or by migrating the virtual machine. Live migration of the virtual machine is useful in the case server failure, server maintenance, load balancing, hot spot mitigation and severs consolidation.
