This document summarizes a proposal for implementing a virtual desktop infrastructure (VDI) at ABC Inc. It includes an executive summary highlighting benefits of VDI like simplified provisioning and centralized management. It then provides an overview of the current desktop challenges, typical corporate desktop models, and advantages of VDI. The objective is to evaluate the financial and operational impacts of VDI solutions. The analysis compares the 5-year total cost of ownership for the current (BAU) environment versus a VDI solution. It finds that while the VDI solution has higher initial capital costs, it provides overall savings of $66,000 over 5 years through reduced operating expenses.

4. Executive Summary
 Over the past years many organization have realized the benefits of server
virtualization. A favorite technology to dramatically compress server footprint
and lowering both capital and operational expenditures.
 IT organizations today are looking for new ways to address their desktop
challenges (Quick provisioning, Windows 7 migration, Patching, Security).
 More recently, desktop virtualization has emerged as a serious topic of
discussion. The concept of consolidating hundreds, or even thousands, of desktop
images onto a single server platform has great appeal to many organizations.
 Gartner recently estimated that the number of virtualized desktops could grow
to 660 million by 2012. Some reasons for the mass appeal are the promise of:
 simplified provisioning of desktops
 centralized desktop management and support
 streamlined new desktop OS upgrades
 secure remote access and Disaster recovery

Infrastructure Overview

6. Desktop Infrastructure Challenges
Limited control of PCs
• Patch compliance
• Security
• Regulatory compliance
Management complexity
• Deployment
• Support
• Security
• Multiple OS images to
manage
Focus on PC hardware
• Many makes & models
• Refresh cycles
• Solutions for aging
hardware
Reducing Cost
•Operating and desktop
maintenance/support
costs

7. Typical Corporate Desktops
Tightly coupled
relationships between
HW,OS, Application and
Data in the corporate
desktop PC model.

8. Typical Corporate Desktops
In most environments,
the components are
linked together in
ways that are difficult
to support and
maintain.

9. Problems Can Start At Any Layer
A problem at one layer
often causes a chain
reaction that can
destroy the whole
stack.

10. Local Failures Can Mean Data Loss
This makes recovery
difficult and threatens
any locally stored user
data and settings.
Most organizations
just replace or re-
image the whole PC.

11. What is Virtual Desktop Infrastructure?
11
Virtual Desktop Infrastructure –it is a concept not a product, an architecture
for running virtual desktops on an ESX server.
Leverage the advantages of the data center for the desktop
Virtual desktop as a concept, separates a PC desktop environment from a
physical machine.
The model stores a “virtualized” desktop on a remote central server
instead of on the local storage of a PC client.
In a virtual desktop model the programs, applications, processes, and data
are stored and run in a centralized server environment.
End users connect to a remote desktop, but have a local experience
Enables a scalable highly available, highly accessible user environment
This allows users to access their desktops on any capable device, such as
a traditional personal computer, notebook computer, smartphone, iPad, or
thin client.
Dominant Products to build VDI: Citrix [XenDesktop XenApp,] VMware [View, ThinApp]

12. Key Points about Virtual Desktop Infrastructure
12
Tasks like procurement of desktop computer hardware, deploying or
patching desktop operating systems, updating antivirus signature,
securing data, and desktop support become more and more challenging as
the size of an organization grows, and the disbursement of employees
across multiple locations increases
Replacing all or a bulk of an organization’s computer workstations with
thin client terminals and managing the client OS and applications in a
centralized location is something most organization would love to be able
to do.
As smartphones, tablets, and other mobile devices become the data
access and communication tools of choice in the work place, the systems
needed to support this new generation of mobility are changing.
Companies supporting bring your own device programs need to deliver
corporate desktops and applications to various mobile devices in a secure
way, and VDI does just that.

13. Advantages of Virtual Desktop Infrastructure
13
Reduced cost in purchasing desktop computers, as thin clients often last
two to three times longer than a desktop computer
Centralized Client OS Management
Rapid Client Deployment
Reduction in desktop support costs
Reduction in electricity costs, as thin client computers use only a
fraction of amount of energy that is used by a desktop computer.
Improved Data Security and centralized data storage
Improved worker productivity because of reduced PC downtime and the
ability to access desktops from multiple locations;
Fewer Application Compatibility Problems than with Terminal Server and
Citrix, as users have their own, single user OS.
Better business continuity and disaster recovery capabilities.
Secured access to corporate data across a wide range of corporate and
employee owned devices including Mac, Windows and Linux devices as
well as iPad and Android tablets.

14. Objective of the Desktop Virtualization
The purpose of this desktop virtualization and application is to provide
decision makers a framework to evaluate the potential financial and
operational impacts of desktop virtualization solutions on the
organization.
The aim is to show the benefits and savings, through calculations and
assumptions used in the analysis.
Note: All simulations and calculations in the slides ahead are based on renown
virtualization software, which is considered as one of the most renowned virtualization
suites available in the market.

15. Virtual desktops are not for everyone. For example, employees who works in
marketing, and Technical team; These type of employees use laptops and mostly
spend much of their time using graphics and video editing software, or use
specialized I/O devices, are usually not good candidates for virtualization. They also
need to install applications themselves for their activities and need administrative
privileges and high-performance desktop, may not be a good fit for VDI.
But many workers are well served by virtual desktops, including “day extenders” that
use laptops only between working hours. The following examples describe standard
virtual desktop usage scenarios:
Ideal Users For Desktop Virtualization
Organization Descriptions
Call center Employee class who relies on only office and web applications seems to be the right candidates (Microsoft’s
Virtual Desktop Infrastructure ).Employees get a session when they arrive that can be permanently or temporarily
assigned. Temporary desktop assignments are ideal for application access, reducing the overhead of provisioning
More desktops. The system ensures there are sufficient desktops available for employee access.
Outsourced staff Outsourced staff performs tasks while sensitive applications and data remain within control of the organization.
Organizations can control when users can access the system and where information can go.
Development & test Instead of providing multiple PCs to employees for development and test activities, provide multiple virtual
desktops, each provisioned with a temporary lease or permanently. Users can access multiple PCs through
thin client.

17. Analysis Summary
This 5-year analysis for ABC Inc calculates the estimated total cost of
ownership (TCO) comparison between current (As Is) environment and
implementing the proposed virtualization solution.
Based upon the information provided, the desktop virtualization
products does not seems to provide any potential IT capital savings
and operating savings over 5 years.
Financial Projections:-
 From TCO analysis overall savings : US$ 66,000 in 5 years!!
Representing a 1.8% improvement in TCO!!
 However from NPV analysis: BAU's NPV is US$216k lower than
VDI’s NPV!!

18. Financial Modeling Overview – Scenario
18
BAU (Business As Usual) Case:
Current: 1000 PCs - assuming that network engineering, executive laptops, marketing etc are not eligible
candidates
Lifecycle distribution – 200PCs each in each slot of ageing (1 yr to 5 yrs old)
YOY growth in PCs and IP ports @10%
New PCs also at some cost, ie, US$900 with 3 yrs warranty
Model the next five years in terms of PC – Capex on account of growth & replacement, and Opex in terms
of maintenance, power & cooling (needed even in user workspace area)
VDI Virtualization Case: Migrate to virtualized environment & grow
Starting Point: Each virtual host server (2Px4C, 2.4Ghz+, 128GB RAM, 4xGeNIC, 2xHBAs) to virtualize
existing 40 PCs- moderate sizing
Thumb rule >> Conservative estimates:32 PCs, Aggressive : 50 PCs, to a virtual host server of above
configuration
Additionally need SAN+ storage for the virtual host servers, Usable disk space on SAN storage= 40GB per
virtualized
Warranty=3 yrs for virtual host servers, existing PCs and thin clients for growth
AMC= 15% ESX servers, 10% on thin clients
YOY growth= 10 %
Model the next five years in terms of virtual host servers, Thin clients & associated equipment, and DC
facilities- Capex on account of growth, DC infrastructure, and Opex in terms of maintenance, power & cooling,
rental costs. All PCs TO BE REPLACED BY THIN CLIENTS, AND FURTHER GROWTH ONLY ON THIN
CLIENTS

24. Key Drivers for Virtualization
VDI is unlikely to result in any significant $ savings. However, its usefulness
is in the "soft" benefits
Higher availability
Improves Manageability
Operations Automation & Effectiveness
Shortens provisioning time.
Environmentally friendly
Data centralization on SAN results in better data protection & backup
Enhanced Compliance and Data Security
Enables “Thin Client” compute capability – Workplace independence from the Data Center in
terms of distance and connectivity B/W constraints
Enables ‘Bring Your Own Device’ policy to deliver corporate desktops and applications to
various mobile devices (i.e. Mac, Windows, iPad and Android tablets) in a secure way.

25. Recommendation
 All tests done in POC with CITRIX and VMware were successful. One
limitation that was found with audio in both the solutions (delay in
propagating sound) remains unresolved but according to vendor this can
be circumvented with next software release around min 2013. Windows
7 didn’t encounter any significant issue.
 Given that the architecture is very complex than server virtualization,
we recommend to start VDI implementation with phased approach and
build the environment incrementally.
 The phase 1 implementation is planned to be done in 2013. First phase’s
cost is already proposed in 0+12, 2013 budget.
 Based on the pricing [Software and License] will move forward to
implement the solution.

27. Desktop Virtualization Implementation - (Phased
Approach)
27
 Total 1000PCs were identified as “candidates for Desktop virtualization”.
 We proposed to migrate these 1000 PCs into virtual desktop in 3 phases
 Proposed Project Phases are:
– Phase 1 : Phase 1 covers replacing 100 PCs into VMs. This phase is
expected to be started in H1 2013 and will require 6 months to complete.
This phase will consider Call Center, Sales and HR & Admin users
– Phase 2 : Phase 2 covers replacing 500 PCs with VMs. This phase is
expected to be started in H1 2014 and will require 6 months to complete.
This phase will consider Call Center and O&M users
– Phase 3 : Phase 3 covers replacing 400 PCs with VMs. This phase is
expected to be started in H1 2015 and will require 6 months to complete.
This phase will consider finance and Technical users who’s profile is fixed,
does not need to install applications themselves for their activities and won’t
require administrative privileges or high-performance desktop.
