-Server Based Computing Model

-Applications run on a central back end server and are displayed ondesktop devices

ingle server can support dozens of devices


5/33

Simple computers designed to run applications from acentral server

lower microprocessor requirements

lower memory requirements than PCs

-providing an identical end userexperience

, ,Smaller some the size of a CD case and most lack removable( ),drives or any drives making it impossible for those using

them to steal electronic data on floppy disk or introduceviruses to the network

designed to cost less than PCs to run and maintain( )reduces TCO

Advantages of Zero ClientOver Thin Client

No

Local ProcessingNoLocally Installed SoftwareQ ,uick efficient and safe to run application

when it is coupled with virtual desktop( ).infrastructure VDI

More compact While thin client operates on Windows CE or

Embedded XP platforms and havecomparatively bigger size of RAM that

,ranges from 16 to 256 MB its competitorworks on completely embedded platforms andhave a much smaller size of RAM that is

.between 4 and 32 MBMu ch more stable and safe from virus


9/33

If you take into contemplation thepower usage, you'd see that on onehand where thin client system uses

somewhere between 15-40W ofpower because of the fans attachedto it, zero client systems use

maximum power of 5W because ofno moving part included with itIt is tougher in its usage, more reliable

and most importantly costs muchlower.

Desktop VirtualizationAdvantages

simpler to apply new desktops

reduced Downtime in both serverand client hardware-failures

lower cost of deploying newapplications

desktop image-managementcapabilities

secure remote access to desktop


30/33

Limitations of desktopvirtualization

challenges in setting up andmaintaining drivers for printers andother peripherals

difficulty in running certain complexapplications (such as multimedia)


31/33

perating SystemApplication virtualization

Features Decouple applications and data from

OS Agent-less architecture Wide platform and application support Plug into existing application

management tools

Benefits Enable OS migrations and streamline

application patch updates Enable application mobility and

flexibility of access Minimize the number of desktop

images managed Eliminate application conflicts Enable the use of multiple versions of

applications

Limitations of application

virtualization

Not all software can be virtualized.Some examples includeapplications that require a device

driver. Some types of software such as anti-

virus packages and applications

that require heavy OS integrationare difficult to virtualize.
