Desktop virtualization System architectures

1 Neither approach explicitly requires the use of a hypervisor; however, in practice most desktop virtualization implementations do incorporate a

hypervisor component.


Desktop virtualization Remote desktop virtualization

1 It should be noted that VDI is often used incorrectly to refer to any

desktop virtualization implementation.



1 Remote desktop virtualization is

frequently used in the following

scenarios:https://store.theartofservice.com/the-desktop-virtualization-toolkit.html


1 Remote desktop virtualization is also used as a means of resource sharing,

to provide low-cost desktop computing services in environments where providing every user with a dedicated desktop PC is either too

expensive or otherwise unnecessary.


Desktop virtualization Remote desktop services

1 The use of a single shared server Operating System instead of individual desktop

Operating System instances consumes significantly fewer resources than the same number VDI sessions. At the same time VDI licensing is both more expensive and less flexible than equivalent Remote Desktop

Services licenses. Together these factor can combine to make Remote Desktop Services-based remote desktop virtualization more

attractive than VDI.


Desktop virtualization User virtualization

1 The major desktop virtualization platform vendors, Citrix, Microsoft

and VMware, all offer a form of basic user virtualization in their platforms.


Desktop virtualization Layering

1 Desktop layering is a method of desktop virtualization that divides a disk image into logical parts to be

managed individually


Desktop virtualization Local desktop virtualization

1 Local desktop virtualization implementations run the desktop environment on the client device using hardware virtualization or

emulation. For hardware virtualization, depending on the

implementation both Type I and Type II hypervisors may be used.


Desktop virtualization Local desktop virtualization

1 For example, while it is possible to use local desktop virtualization to run Windows 7 on top of OS X on an Intel-based Apple Mac, using a

hypervisor such as VirtualBox, Parallels Desktop for Mac, or VMware Fusion, as both use the same x86 architecture, and as it was possible to run Windows on a PowerPC-based

Mac using Virtual PC, it is currently not possible to run Windows 7 on an ARM-based tablet, as there are no emulators that run on those tablets and emulate an x86-based PC.


Virtualization - Desktop virtualization

1 Desktop virtualization is the concept of separating the logical desktop from the

physical machine.



1 One form of desktop virtualization, virtual desktop infrastructure (VDI), can be thought as a more advanced

form of hardware virtualization



1 Desktop virtualization simplifies software versioning and patch

management, where the new image is simply updated on the server, and the desktop gets the updated version

when it reboots

Workspace virtualization - Workspace Virtualization vs Desktop Virtualization

1 When it comes to system resources, Workspace Virtualization requires

fewer resources than Desktop Virtualization because it doesn't contain a complete copy of the Operating System running in a

virtualization environment


Multiseat desktop virtualization

1 'MultiSeat Desktop Virtualization' is a method by which a common desktop

Personal computer|PC, with extra Keyboard (computing)|keyboards, mice, and video screens directly

attached to it, can be used to install, load, and concurrently run multiple

Operating Systems


Multiseat desktop virtualization - Multiseat desktop virtualization differences

1 Multiseat desktop virtualization is an entirely new methodology which

combines the cost saving benefits and ease of maintenance of server

based computing, the time savings of hardware agnostic cloning, and the

capabilities of desktop virtualization, with the performance capabilities of

real PC functionality


Virtualisation - Desktop virtualization

1 Desktop virtualization is the concept of separating the Desktop

environment|logical desktop from the physical machine.


Virtualisation - Desktop virtualization

1 Thin clients, which are seen in desktop virtualization, are simple and/or cheap

computers that are primarily designed to connect to the network. They may lack

significant Hard disk drive|hard disk storage space, Random access memory|RAM or even Central processing unit|processing power, but

many organizations are beginning to look at the cost benefits of eliminating “thick client”

desktops that are packed with software (and require software licensing fees) and making

more strategic investments.


Desktop Virtualization

1 'Desktop virtualization' is software technology that separates

the desktop environment and associated application software from the physical client device that is used

to access it.

1 Below are more detailed descriptions of the types of desktop virtualization technologies that will be used in a typical deployment.

1 Neither approach explicitly requires the use of a hypervisor; however, in practice most desktop virtualization implementations do incorporate a

hypervisor component.


Desktop Virtualization - Desktop as a Service

1 Remote desktop virtualization can also be provided via a Cloud computing similar to

that provided using a Software as a service model. This approach is usually referred to as

Desktop-as-a-Service (DaaS). The DaaS provider typically takes full responsibility for

hosting and maintaining the compute, storage and access infrastructure, as well as

applications and application software licenses needed to provide the desktop service in

return for a fixed monthly fee.

1 One form of desktop virtualization, virtual desktop infrastructure (VDI),

can be thought of as a more advanced form of hardware

virtualization
