Compared January 14, 2011 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 iPad lead shrinks as
tablet sales grow Android tablets -- mostly
Samsung's Galaxy Tab -- take 22 share in Q4

What Is Desktop Virtualization?
Evolution of End-user Computing
Another Way to Put It
  • Traditional Desktop Model
  • Asset maintenance and support costs
  • Deployment and configuration of hardware
  • Management of app and OS configurations
  • Troubleshooting
  • Virtual Desktop Model
  • New desktop and new or upgraded application
    stacks delivered by updating central image
  • Eliminates need to individually deploy or
    configure new desktop hardware

What can we do?
Otherwise known as Centralize, Virtualize, and
Deliver on Demand
Remote Worker
Mobile Worker
Separate Applications and Operating Environments
Local Users
  • Move applications and data from individual
    machines to the data center
  • Maintain and test in one secure place
  • Deliver instantly and on-demand to any device,

Quality of service is dependent on hosting

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 govt 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
convenientPC, 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,
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 Its 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 analysis

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 users machine and reload a new master
    image (with applications, student exercises,

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
  • Their virtual desktops (with their settings and
  • Their email
  • Their files
  • All securely (with dual authentication, if
  • While user data and files are kept within the
  • 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

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
  • 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 synced 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
Provide remote users access to virtual desktops
from their own access devices at home instead of
deploying laptops
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

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

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

  • Server Capacity
  • Network Storage

Stop Light Analysis
Proof of Concept
  • Assess current infrastructure, applications,
  • What applications can and cannot be migrated
  • Outline benefits risks, with architecture and
  • A step by step process to move you towards a
    virtualized environmnent

Conducting a Successful Proof of Concept
POC Requirements List
  • A good requirements list
  • Is discretely measurable
  • Is comprehensive
  • Some examples
  • User needs to load email application and be ready
    for user input within 15 seconds
  • User must not have access to Windows 7 games
  • 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)

  • Conclusion

  • 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
  • There are many configurations possible
  • find the low-hanging fruit in your organization,
  • find a trusted partner and GET STARTED
