What is Virtualization

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.

In computing, virtualization refers to the act of creating a virtual (rather than actual) version of something, including virtual computer hardware platforms, operating systems, storage devices, and computer network resources.

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.

The creation of a virtual (rather than real) version of something such as an operating system, a server, a storage device or network resources.

The act of creating virtual computer hardware, storage devices, and/or computer network devices.

It allows you to use a physical machine’s full resource by distributing its capabilities among many users, environments, or virtual machines.

The division of a computer into multiple execution environments so that one level (e.g. the physical) can be abstracted from another (e.g. the operating system).

A machine, which can switch to previous instances, paused and restarted easily.

Virtualization refers to the way of hiding the physical characteristics of the computing resources in a way in which other applications or systems interact with those resources.

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.

A base component of the cloud that consists of software that emulates physical infrastructure.

Profoundly transforming how people connect with each other in ways that supersede activities in the physical world. Virtualization and its impact are best understood in reference to three core concepts: 1) Digital transformation is not perpetual, 2) is critical to reaching today’s audiences, and 3) is critical to reaching today’s audiences (Media.Monks, 2022).

The creation of a virtual version of something, such as a server, a storage device, network resources, or an operating system.

Virtualization, in computing, is the creation of a virtual (rather than actual) version of something, such as a hardware platform, operating system, a storage device or network resources.

A trend in IT that separates hardware from the software. Cloud computing, for example is the virtualization of computer program which allows its user to use different software through the Internet without needing to have installed all the software.

Virtualization is a technology that enables the creation of virtual instances or representations of computer resources, such as servers, storage, or networks. This allows multiple virtual environments to run on a single physical hardware, leading to better resource utilization, improved scalability, and energy efficiency.

The creation of a virtual—rather than actual—version of something, such as an operating system, a server, a storage device or network resources.

A logical view of a computing resource, in many cases a computer but also possibly storage or networking.

Virtualization is a software technology that uses a physical resource, such as a server, and divides it into virtual resources called virtual machines (VMs). Virtualization helps to consolidate physical resources, simplify deployment and administration, and reduce power and cooling requirements.

Is simulating a network resources, giving an application program the impression that it has contiguous working memory, isolating it from the underlying physical memory implementation.

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.

Computer term which generally refers to a structure given to a physical server which allows to host several emulated servers. These can interact independently with other devices and users, as if they were physical resources themselves.

Virtualization is a technique for hiding the physical characteristics of computing resources to simplify the way in which other systems, applications, or end users interact with those resources.

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.

It refers to creation of a virtual (rather than actual) version of something, including but not limited to a virtual computer hardware platform, operating system (OS), storage device, or computer network resources.

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.
