CNIT 242 Chapter 18 Application & Desktop Virtualization

T/F Individual resources can be virtualized without virtualizing the entire platform

True

T/F Almost any individual resource can be virtualized

True

Benefits

Provide access to resources that don't exist

Provision resources more efficiently

Share resources among several physical devices

Resource Virtualization

Complete abstraction of local storage

Network shares

RAID Arrays

SAN and NAS

Storage Virtualization

Virtualized VLANs

Network Virtualization

Grid computing

CPU Virtualization

____ allows apps to be encapsulated from the underlying OS

App virtualization

Apps are installed and configured in a bubble

and then the bubble is made available to clients

The bubble virtualizes resources such as environment variables, registry keys, etc.

The app bubble is used to execute the app and deleted when execution is over

Application Virtualization

All application bubbles reside on an ____

application server

T/F Apps can run in non-friendly environments

True

Eliminate application conflicts

Protect underlying OS from poorly written apps

Force apps to run in a less-privileged OS mode

Can simplify application rollouts

Application Virtualization Benefits

These are what

VMware Thinapp

Microsoft App-V

Novell ZENworks Application Virtualization

Citrix XenApp

Etc...

Application Virtualization Solutions

Links a virtual operating environment with an embedded file system to provide a single executable

VMware Thinapp

T/F VMware Thinapp requires an agent

False it does not

The virtual environment is "merged" with local

resources so everything appears local

VMware Thinapp

____% of companies are investing some money into desktop virtualization

Only ____% of desktops are currently virtualized

41% 6%

Decouples desktop environments from the underlying PC hardware

Sometimes called VDI

Virtual Desktop Infrastructure (or Interface)

Desktop Virtualization

T/F Unlike server virtualization, hardware consolidation is not a goal of desktop virtualization

The main goal revolves around ease of desktop management

True

O/S, data and apps are stored centrally and presented to users using virtualization.

Desktop Virtualization

Desktop delivery is considered a "____"

managed service

Benefits

Users can access data and apps without being tied to specific hardware

Remote access to standard desktop environments andv applications

Desktop Virtualization

T/F Almost all aspects of a users' desktop can be centrally managed

Can maintain 1:1 desktop images to users

Almost all aspects of a users' desktop can be centrally managed

Can maintain 1:many desktop images to users

Standard OS, apps, patch level, corporate compliance, etc.

False 1:many

T/F Using Desktop Virtualization, Desktops can be easily provisioned to new users

True

T/F Without Desktop Virtualization, desktop environments can be managed as VMs

VMotion, remote storage, etc.

False with desktop virtualization

Similar to server virtualization, single points of failure can exist

Low level of support for complex client/server apps or driver/hardware compatibility

Security can be an afterthought

Lack of standardization for PC hardware

Users' perception

Loss of autonomy

Loss of privacy

Desktop Virtualization Disadvantages

Citrix XenDesktop

Microsoft Enterprise Desktop Virtualization

(MED-V)

Others

Desktop Virtualization Vendors

T/F Some solutions require an agent, others don't

True

What are the user's perception of Desktop Virtualization

Loss of autonomy

Loss of privacy
