The process of virtualization enables the creation of virtual forms of servers, applications, networks and storage. The four main types of virtualization are network virtualization, storage virtualization, application virtualization and desktop virtualization.

Virtualization
3. Virtualization is the technology which enables the creation of a virtual version of applications,
network resources, storage devices and computer hardware platforms. It is the process that
makes it possible to create multiple simulated environments from a single hardware. It uses a
software to install multiple OS (Operating Systems) on a system and lowers IT expenses as
well as augments efficiency.
Virtualization can be of various types, such as network virtualization, storage virtualization,
application virtualization, server virtualization and desktop virtualization. The content of this
PPT focuses on desktop virtualization.
To digress, servers are used by web hosting companies for the purpose of storing the files of
websites to keep websites up and running. Web hosting companies use different types of
servers, such as dedicated, VPS etc. Terms such as “Self Managed Windows VPS”, “Self Managed
Linux VPS”, “Managed Windows VPS” etc. refer to the various types of servers that are used by
web hosting service providers.

4. Desktop Virtualization refers to the technology that enables simulation of workstation load by
users for the purpose of accessing a desktop from a remotely or locally connected device. This
helps to segregate the desktop environment along with its applications from the client device
that is used to access it. This type of virtualization is an important element of workspaces that
are digital and it depends on application virtualization.
Desktop virtualization is a type of client-server computing model. That is because the
virtualized desktop gets stored on a server that is centralized or remote. Virtual desktop
environments are made accessible to users on the network. Desktop virtualization enables
remote log in for accessing one’s desktop from any location.

5. Although there are various ways to attain desktop virtualization, two types of desktop
virtualization are the most important. These are Remote Desktop Virtualization and Local
Desktop Virtualization. This classification depends on whether the OS (Operating System)
instance is remote or local. Each of these will be discussed in the next two slides.

7. Remote Desktop Virtualization functions in a client/server computing environment. This type of
virtualization presents a common use of virtualization and lets users run applications and OS
from a server that is inside a data center. All user interactions in this type of virtualization
happen on a client device, such as a laptop, a smartphone etc.
Remote Desktop Virtualization enables IT departments to exercise centralized control over
desktops and applications.

8. In Local Desktop Virtualization, the OS runs on a client device by using hardware virtualization.
All the processing and workloads in it take place on local hardware. Such a virtualization is a
good option when a continuous network connection is not required by users and when they
can fulfil application computing needs through local system resources. Since processing happens
locally, one can’t use this type of desktop virtualization for the purpose of sharing virtual
machines or resources across a network to mobile devices or to thin clients.

9. Desktop virtualization offers many benefits depending on the deployment model that has been chosen. Its major
benefits are mentioned below, in no particular order.
Reduced IT costs
Reduced downtimes
Accelerated deployments
Better user experience
An increase in the productivity of employees
Simplified administration and resource management
Mobile access to apps
Remote work

Benefits of DesktopVirtualization
10. The major drawbacks of desktop virtualization are mentioned below.These are in no particular order.
Capital expenditure intensive
Doesn’t reduce the number of computers that are required in the network
Users’ licenses for OS and applications need to be bought, without any reduction in costs
Thin-clients are often more expensive than individual computers
Extra bandwidth needs to be handled by the network infrastructure
It is challenging to handle high-definition video/graphics
Certain vendor solutions work exclusively with their server virtualization counterparts
Desktop virtualization products support a limited number of OS
Display quality might suffer when there is insufficient bandwidth on the remote end
