Data that's spread all over can be consolidated into a single source . allows companies to treat data as a dynamic supply —providing processing capabilities that can bring together data from multiple sources, easily accommodate new data sources, and transform data according to user needs .

Types of Virtualization

Desktop, Data, Network, Storage, Server, Application, Cloud

Virtual Machine

Each _________ 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.

A P P L I C A T I O N V I RT UA L I Z A T I O N

This is when an application is stored virtually on a server and then accessed by the user's device through the server, instead of being installed directly on the device

S E RV E R V I RT UA L I Z A T I O N

This is when more than one virtual server can be stored on one physical server . Instead of purchasing more and more physical servers, you can save on floor or room space, and instead virtualize multiple servers and store them on one single machine instead . It also means you can easily allocate physical resources between different servers and change it as necessary.

Virtualization

a process that allows for more efficient utilization of physical computer hardware.

Virtualization

a standard practice in enterprise IT architecture.

Virtual Desktop Infrastructure (VDI)

a technology used to create a virtualized environment in which the hardware is segmented into different virtual desktops. These virtual desktops are hosted on a central server.

D A T A C E N T E R V I RT UA L I Z A T I O N

abstracts most of a data center's hardware into software, effectively enabling an administrator to divide a single physical data center into multiple virtual data centers for different clients.

S T O RA G E V I RT UA L I Z A T I O N

allows applications and servers to access information from storage systems without needing to know which physical or virtual device the data is stored on . Virtualizing storage allows data to be easily backed up and transported between locations, and data can be more easily accessed .

virtual machine (VM)

are often referred to as a guest while the physical machine they run on is referred to as the host.

virtual machine (VM)

are virtual environments that simulate a physical compute in software form.

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.

Desktop virtualization

creates a virtual desktop . In this way, the user can move his personal workplace, as it were, and it remains accessible everywhere and at all times . The basic operation that achieves this is relatively simple : one separates the desktop from the device on which it is used .

Type 1 or " bare-metal"

interact with the underlying physical resources, replacing the traditional operating system altogether . The most commonly appear in virtual server scenarios .

virtual machine (VM)

is a virtual representation, or emulation, of a physical computer.

hypervisors

is the software layer that coordinates VMs. It serves as an interface between the VM and the underlying physical hardware, ensuring that each has access to the physical resources it needs to execute.

N E T W O RK V I RT UA L I Z A T I O N

is when physical networks are combined into a virtual network based on software instead of hardware .

Virtualization

it enables cloud users to purchase only the computing resources they need when they need it, and to scale those resources cost-effectively as their workloads grow

Virtualization

n enables cloud providers to serve users with their existing physical computer hardware

Type 2 hypervisors or " Hosted"

run as an application on an existing OS . Most commonly used on endpoint devices to run alternative operating systems, they carry a performance overhead because they must use the host OS to access and coordinate the underlying hardware resources .

hypervisors

separate the physical resources from the virtual environments—the things that need those resources.

Virtualization

the foundation of cloud computing.

S T O RA G E V I RT UA L I Z A T I O N

the process of combining a group of physical storage devices into one group as if they were one device . A commonly known type of virtual storage is called a Storage Area Network , or SAN .

Virtualization

the technology that drives cloud computing economics.

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).
