Virtualization allows multiple operating system instances to run concurrently on a single computer; it is a means of separating hardware from a single operating system. Each “guest” OS is managed by a Virtual Machine Monitor (VMM), also known as a hypervisor.

What is Virtualization?
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.

Definition - What does Virtualization mean?

Virtualization refers to the creation of a virtual resource such as a server, desktop, operating system, file, storage or network.

The main goal of virtualization is to manage workloads by radically transforming traditional computing to make it more scalable. Virtualization has been a part of the IT landscape for decades now, and today it can be applied to a wide range of system layers, including operating system-level virtualization, hardware-level virtualization and server virtualization.

Benefits of Virtualization:

Virtualization can increase IT agility, flexibility, and scalability while creating significant cost savings. Workloads get deployed faster, performance and availability increases and operations become automated, resulting in IT that's simpler to manage and less costly to own and operate. Additional benefits include:
*Reduce capital and operating costs.
*Minimize or eliminate downtime.
*Increase IT productivity, efficiency, agility and responsiveness.
*Provision applications and resources faster.

Server Virtualization?

Definition - What does Server Virtualization mean?
Server virtualization is a virtualization technique that involves partitioning a physical server into a number of small, virtual servers with the help of virtualization software. In server virtualization, each virtual server runs multiple operating system instances at the same time.

Data Virtualization?

Definition - What does Data Virtualization mean?
Data virtualization is the process of aggregating data from different sources of information to develop a single, logical and virtual view of information so that it can be accessed by front-end solutions such as applications, dashboards and portals without having to know the data's exact storage location.

Storage Virtualization?

Definition - What does Storage Virtualization mean?
Storage virtualization is the process of grouping the physical storage from multiple network storage devices so that it looks like a single storage device.
The process involves abstracting and covering the internal functions of a storage device from the host application, host servers or a general network in order to facilitate the application and network-independent management of storage.
Storage virualization is also known as cloud storage.

Network Virtualization?

Definition - What does Network Virtualization mean?
Network virtualization refers to the management and monitoring of an entire computer network as a single administrative entity from a single software-based administrator’s console. Network virtualization also may include storage virtualization, which involves managing all storage as a single resource. Network virtualization is designed to allow network optimization of data transfer rates, flexibility, scalability, reliability and security. It automates many network administrative tasks, which actually disguise a network's true complexity. All network servers and services are considered one pool of resources, which may be used without regard to the physical components.

Network virtualization is especially useful for networks experiencing a rapid, large and unpredictable increase in usage.

The intended result of network virtualization is improved network productivity and efficiency, as well as job satisfaction for the network administrator.

Desktop Virtualization?

Definition - What does Desktop Virtualization mean?
Desktop virtualization is a virtualization technology that separates an individual's PC applications from his or her desktop. Virtualized desktops are generally hosted on a remote central server, rather than the hard drive of the personal computer. Because the client-server computing model is used in virtualizing desktops, desktop virtualization is also known as client virtualization.

Linux Virtualization?

Definition - What does Linux Virtualization mean?
Linux virtualization is a process through which one or more virtual machines can be installed, executed and maintained on top of the Linux operating system. Linux virtualization enables the consolidation of hardware and software resources used by the Linux OS, and allows them to be shared and divided across several virtual machines and their associated processes.
