    Overview Introduction

    In traditional business environments, workers suffer from

    productivity loss in many ways, including downtime during PC

    refreshes, patches and updates, or simply when they are away from

    the ofce. Application and desktop virtualization centralizes apps

    and desktops in the datacenter, rather than on local devices. Thisallows IT to deliver apps and desktops to users on demand, to any

    device, anywhere.

    Experience from the eldTake the following response from a desktop virtualization user. As

    a remote employee for [company], I struggled every time I needed

    to access the companys intranet, which forced me to VPN into

    the network. I also kept data on my local device because tryingto access it over my broadband connection was too slow. Some

    coworkers did the same and lost data due to a virus, thankfully I was


    Depending on my mood (and the weather), changing devices and

    locations was a challenge as I had to have my applications and

    data copied to many different endpoints. I know this was unsecure,

    but I didnt care because I was more concerned with exibility.

    Since moving to a virtual desktop, Im able to use any device. Im

    able to work from any location. And best of all, I dont have to worryabout copying my data and applications onto all of my personal

    devices. I paid for these devices; I dont want work to clutter up my

    personal space.

    Unfortunately, organizations sometimes struggle to achieve this

    level of success. Why does one organization succeed while another

    organization struggles?

    If we compare the factors between success and failure between

    desktop virtualization and other technology related projects, we see

    that there is little difference:

    Lack of justication Without a solid business reason, desktop

    virtualization is simply a new way to deliver a desktop. A business

    justication gives the project team a goal to strive towards.

    Lack of a methodology Many people who try and struggle to

    deploy a desktop virtualization solution do so because they jump

    right in without understanding or implementing the appropriate

    prerequisites. A structured methodology provides the path for the


    Lack of experience For many who embark on a desktop

    virtualization project, there is a lack of experience, which creates a

    lack of condence in the design. Architects begin to second-guess

    themselves and the project stalls.

    Our hope is that this handbook can alleviate the anxiety associated

    with desktop virtualization by showing how challenges can be

    resolved in a manner that is technically sound, but also feasible and

    effective for organizations facing deadlines and other organizational


    Citrix Consulting has successfully employed the methodology,

    experience and best practices shared within this handbook across

    thousands of desktop virtualization projects.

    The Citrix Virtual Desktop 5.xand Virtual Desktop 7.x handbooks are

    not the only resource to guide you through the desktop virtualizationjourney. Citrix also provides Project Accelerator; an interactive

    online tool creating customized sizing and design recommendations

    based on the methodology, best practices and expert advice

    identied within this handbook.

    MethodologyThe Citrix Virtual Desktop Handbook follows the CitrixConsulting methodology. A proven methodology that has been

    successfully employed across thousands of desktop virtualization

    projects. Each phase includes guidance on the important questions

    to ask, what tools to use and tips to help you succeed. The Citrix

    Consulting methodology consists of ve phases:

    Dene Builds the business case for desktop virtualization by

    creating a high-level project roadmap, prioritizing activities and

    estimating storage and hardware requirements.

    Assess Key business drivers are rated so that work effort canbe prioritized accordingly. In addition, the current environment is

    reviewed for potential problems and to identify use cases for the

    project. This information will be used to set the direction of the Citrix

    deployment, upgrade, or expansion.

    Design Dene architecture required to satisfy key business

    drivers and success criteria identied during the assess phase.

    Topics such as environment scalability, redundancy and high

    availability are addressed.

    Deploy During the deploy phase,

    FlexCast Infrastructure is installed and

    congured as described in thedesign

    phase. All components of the infrastructure

    should be thoroughly unit and regression

    tested before users are provided with access to the


    Monitor Dene architectural and operational processes required

    to maintain the production environment.

    The Citrix Consulting methodology follows an iterative Assess >

    Design > Deploy process for each major initiative of your project.

    In doing so, your organization is left with tangible improvements tothe environment at the end of each engagement. For example, high

    priority user groups can progress through the assess, design and

    deploy phases earlier than other user groups

    Note: The Virtual Desktop Handbook provides content on the

    Assess and Design phases of the Citrix Consulting methodology.

    Additional phases will be released soon

    Overview Project Plan

    A detailed, up-to-date project plan is vital to the success of

    the project. The project manager should use the project plan

    to monitor costs, manage project staff, follow progress against

    milestones and track key dependencies such as hardware, storage,

    training, licenses and certicates so that they can be addressedbefore they can become bottlenecks. The project plan should be

    regularly distributed between project team members to ensure that

    everybody is aware of progress as well as remaining tasks.

    At the start of the project, only plan for the Assess phase. You wont

    be able to plan for the Design or Deploy phases yet because youll

    need a better understanding of the FlexCast models, capabilities,

    user groups and applications required. After the roadmap stage,

    update the project plan to include separate design and deploy

    activities for each user group identied, ordered by priority. This will

    help to ensure that the business receives maximum value from their

    investment as soon as possible and allow infrastructure to be built

    out in manageable IT projects that minimize risk and maximize the

    chance for project success.
