It's been raining tablets here at CES 2011. No
seriously, it as if the sky has opened up in Vegas and dropped
touchscreen slabs with Android and Windows 7 operating systems on
our heads. It's been nearly impossible to keep track of the number of
tablets released and the detail

What Is Desktop Virtualization?
Evolution of End-user Computing
From
Server-based
Computing
To
Distributed
Computing
Another Way to Put It:
The Age Old IT Problem
Traditional Desktop Model
•Asset maintenance and
support costs
•Deployment and configuration
of hardware
•Management of app and OS
configurations
The Solution
Virtual Desktop Model
•New desktop – and new or
upgraded application stacks –
delivered by updating central
image
Virtual Desktop Model
•Eliminates need to individually
deploy or configure new
desktop hardware
•Troubleshooting

What can we do?
Otherwise known as:
Centralize, Virtualize, and Deliver on Demand
Separate Applications
and Operating
Environments
•
Move applications and
data from individual
machines to the data
center
•
Maintain and test in one
secure place
•
Deliver instantly and ondemand to any device,
anywhere

Traditional Distributed Computing
IT Focus
Service
End User
Virtualized Desktops
The focus is on acquisition,
configuration, and deployment
of distributed hardware assets.
The focus is on delivery of a
centrally hosted desktop
computing experience to end
users.
Ongoing support involves
configuration and deployment of
applications, and OSs across
distributed assets.
Quality of service is dependent
on hosting servers, network,
connection brokering, and
endpoint access devices.
Desktop PC is the focal point
between user needs and IT’s
ability to deliver service. PC
support is critical to service
levels.
The desktop access device is no
longer the focal point. Drive
endpoint maintenance and
support toward zero while
maintaining or improving

How Does Application Virtualization Help?
Application Virtualization:
Four Simple Steps
First: Centralize Applications
Centrally configure, store, and maintain a
single (or a few) application image(s) in the
datacenter, either on multi-user terminal
servers or centralized virtual machines
Enable seamless delivery from any operating
system.
Application Virtualization
Second: Configure Access
System intelligence and configurable access
controls automatically determine the optimal
method for delivering each application based
on the user scenario, device capabilities,
network performance, connection location, and
security profile
Granular access depending on who you are
and where you are connected from
Example: Connection from gov’t issued device
gets all access, while same user connected
from mobile device cannot download or print
Application Virtualization
Third: Enable Self-Service
(If Desired)
Users can subscribe to the applications they
need from a simple enterprise app storefront
and gain instant access from whichever device
is most convenient–PC, Mac, netbook, tablet,
or smartphone
Think of ITunes app store
In addition, users can use self-service to
perform routine help desk functions (password
resets, etc.)
Application Virtualization
Then: Deliver Apps on Demand
XenApp delivers applications via a high speed
delivery protocol for use while connected:
Streamed vs Hosted mode
Copied to the device for use when offline
(Offline Mode)
Application Virtualization
And It’s Enterprise Ready
Enable as few as two servers or scale on
demand to support multiple datacenters, more
than 100,000 concurrent users, and even
multiple sites throughout the world
IT can ensure rapid response to business and
user needs with built-in comprehensive
management capabilities that enable rapid
provisioning, centralized control, workflow
automation, and system-wide performance

Desktop Virtualization Benefits for IT
• Reduce desktop support costs by up to 40% through
centralized desktop & app deployment and management, and
improved desktop reliability.
• Boost productivity and flexibility by providing users with
anywhere and any-device access to their work.
• Bolster security of user data and simplify DR by separating
desktop processing & storage from desktop hardware.
• Lower operational expenses by extending the life of desktop
hardware

Use Cases for Desktop/Application Virtualization
Classroom Environment
Scenario: A new class is taught each week
Traditional Method:
• An IT administrator works all weekend:
•
Wipe old images
•
Clean old user data files
•
Go to each user’s machine and reload a new master image (with
applications, student exercises, etc.)
Classroom Environment
Scenario: A new class is taught each week
With Desktop Virtualization:
• Accomplished with about 5 mouse clicks.
•
Old Virtual Desktops blown away
•
New Virtual Desktops provisioned from a template, either pushed to
the device or instructor tells student which image to use
•
Green user space created
Telework Environment
Telework Enhancement Act of 2010
According to the U.S. Office of Personnel Management,
only 102,900 federal employees were teleworking in
2008. That figure represented only a fraction of the
1.2 million who were estimated to be eligible to do so
A Few Facts:
• 62% of federal workers eligible to work remotely
• $100 Million - Estimated loss (in salary $ per day)
during government closures due to snowstorms, etc.
• 150,000 - Goal of Obama administration for teleworkers
by 2011 (46% increase)
Telework Environment
With a virtualized environment users have access to:
•
•
•
•
Their virtual desktops (with their settings and preferences)
Their email
Their files
All securely (with dual authentication, if required)
While user data and files are kept within the datacenter:
• Effective security
• Ease of patch application
• Reliable backup
IT does not have to worry what endpoint the user is connecting from
(remember: Hosted or Streamed mode)
Telework Environment
If 40% of the U.S. population that holds telework-compatible
jobs and wants to work from home did so half of the time:
280,000,000 barrels of oil saved (37% of Gulf oil imports)
equivalent of taking 9 million cars permanently off the road.
The gas savings would total more than twice what the U.S.
currently produces from all renewable energy sources
combined
Offline Workers
Only for users with this permission
Users automatically download packages (applications)
and have offline access to those applications and
corresponding data while away
When they return (automatic timeout avail), license is
“returned,” user data is sync’ed and users return to
Streaming or Hosted mode
Excellent for:
•Investigators
•Census workers
•Frequent travelers
How to Get Started
Focus the Pilot on Delivering Quick Wins
and Short-term Savings
Consider the following scenarios of “low-hanging fruit”
Secure Home Access
Provide remote users access to virtual desktops from their
own access devices at home instead of deploying laptops
Why it works…
Laptops are often used to provide work-at-home users with
access to a secure desktop providing a DR option
Implementers have saved by providing remote access to
secured virtual desktops instead without sacrificing user
experience

and Short-term Savings
New PC Candidates
Pilot with users ready for a new PC to secure participation
and user buy-in
Why it works…
Users will be more willing participants given degraded
performance on their old PC, and often see a performance
boost on the virtual desktop
It may also be possible to provide them with a performance
and software upgrade without upgrading their hardware

Focus the Pilot on Delivering Quick Wins
and Short-term Savings
Virtual Test Lab
Create a test lab of server hosted virtual PCs to test a new app
or OS upgrade
Why it works…
This will eliminate the need to build out separate hardware for
a pilot group to try out a new OS and software (such as
Windows 7) because they can access upgraded hosted VMs
from current hardware
The virtual test lab is cheaper and less disruptive for testers

Conducting a Successful Proof of Concept
POC Requirements List
A good requirements list :
1. Is discretely measurable
2. Is comprehensive
Some examples:
1.User needs to load email application and be ready for user
input within 15 seconds
2.User must not have access to Windows 7 games
3.User must have access to their existing files on a shared
drive upon boot
Top 5 Mistakes in Conducting a
Proof of Concept
5. Application virtualization strategy
4. Optimize anti-virus
3. Manage boot storms
2. Proper storage configuration
1. Calculate network impact
(client tuned to network performance)

Desktop Virtualization is powerful for IT and flexible for
the user
Application virtualization adds strength to the offering or
stands alone to deliver applications to users
