Executive summary
Companies have come to realize that they can increase employee productivity
through programs such as Bring Your Own (BYO), mobile anytime anywhere anydevice access, and work shiting while streamlining operational costs by using
desktop virtualization. Virtual Desktop Inrastructure (VDI) can ree end users romthe tethers o their desktop computers and enable them to access corporate
desktops anytime rom any device, including tablets and mobile phones. The resultis a more agile, responsive and secure computing environment that scales quickly,
creating real market advantages in todays ast-paced business world.
As enterprises adopt VDI and increase business agility while reducing supportcosts, other businesses want to do the samebut ace tight resource and budget
constraints. Many VDI solutions are designed or enterprises and are an extension toserver virtualization, requiring the same type o datacenter setup, along with expert
IT resources. While companies can amortize the costs or such a ootprint, thisapproach requires a high upront investment, and i the number o virtual desktops
is low or phased in gradually, it can take a long time or a business to generate areturn on investment (ROI). For both these reasons, traditional ways o delivering VDIsimply dont work outside the enterprise.
In this white paper, we examine the top ve VDI considerations or businesseslooking to simpliy VDI and compare two approaches to implementing VDI:
the traditional enterprise VDI architecture and VDI-in-a-Box with ashared-nothing architecture.
Top ve considerations or businesses looking tosimpliy virtual desktops
1. Cost
No matter what size your organization, make sure you actor in both the hardand sot (direct and indirect) costs associated with VDI implementation in order
to come up with an accurate total project cost. In particular, considerthe ollowing:
Inrastructure costs or production use with high availability. You cannotaord to take chances with the availability o your VDI desktops. Ater all, VDI issupposed to improve agility, mobility and eciencynot leave large numbers o
users at the mercy o a single point o ailure. Make sure you extrapolate beyondthe pilot deployment to assess the costs associated with deploying a VDI that
can support high availability and scale on demand in a production environment.Assess upront the total cost o the physical servers, shared storage such as a
storage area network (SAN), load balancers, connection brokers, managementand provisioning servers and any other inrastructure needed or yourproduction deployment.

Upront costs. You probably want to start small and grow incrementally.Traditional VDI solutions are not cost-eective on a small scale because they
require a large xed upront investment which can only be cost eective orseveral hundreds o desktops. Consider both the ultimate size o your planned
deployment and whether it will take place in phases. Many companies rereshdesktops when PCs break or become obsolete, and have pre-allocatedbudget or this. I you plan to re-purpose such budgets to start your VDI
deployment, check that the upront investment required by the VDI solutionyoure considering ts within your budget constraints.
Cost o resources. Estimate the cost o the expertise needed to deployand manage the VDI solution. Does your team have expertise in desktop
and Windows administration, storage and SAN, virtualization managementand high-end networking? Would you rather have a Windows/desktop
administrator set up and manage virtual desktops without signicant re-training on other components and technologies?
2. Simplicity
Traditional desktop virtualization deployments require enterprise resources andexpertise, and typically take weeks to months to complete.
This can be a challenge or non-enterprises that are looking or implementationtimes in hours or days.
Calculate the complexity o the proposed VDI solution careully, looking past
the proo o concept to the time and resources it will take to roll out virtualdesktops in production. As you evaluate the number o hardware and sotware
components the solution will require, bear in mind that as the number ocomponents in a solution increases, the longer it will take to diagnose and
debug any issues that arise. The more complex a solution, the greater its
number o potential ailure points, which decreases overall reliability. Notice,too, the number o editions (trims) o VDI solution that your vendor oers and
which one youd need or production-quality, highly available virtual desktops.
As you size up each component, consider the resources that it might require,
and investigate whether youd need new sta with a specialized skillset toinstall and manage it. You might also nd youd need a separate crew to
manage the whole solution.
Thus, do ocus on just how simple is the VDI solution under consideration.Most companies do not have wherewithal to handle a complex VDI solution.
3. Scalability and high availability
Plan rom the outset how you can scale the solution over time. I the solutionrelies on shared storage, scaling may create bottlenecks such as bootstorms that you can only overcome by expensive over-provisioning with high-speed interconnects and higher-end SANs. Look instead or a solution that
can scale in cost-eective steps to match your needs. Enterprises are usedto overprovisioning costs, but i you are not, consider the budget impact o
scalability-related overprovisioning.

can connect servers to orm a highly available grid, which you can easily scale upby adding more servers. The grid automatically balances loads and delivers high
availability. VDI-in-a-Box has been purpose-built to simpliy and streamline virtualdesktops, so that you get a production-quality solution with built-in high availabilityor less than the cost o PCs.
VDI-in-a-Box eliminates management overheadThe picture below compares a production deployment setup using traditional
VDI with VDI-in-a-Box. A traditional VDI deployment includes a pair each o loadbalancers and connection brokers to manage the desktop sessions and ensure
high availability and servers to provision and manage the desktops. VDI-in-a-Box consolidates all this unctionality into its virtual sotware appliance, buildingin connection brokering, load balancing, high availability; desktop provisioning
and management. This radically simplies the setup and management andlowers costs.
VDI-in-a-Box delivers high availability without shared storage
Traditional VDI solutions require shared storage, typically a SAN with high-speedinterconnects, to deliver high availability in production settings. This is expensive.VDI-in-a-Box eliminates this requirement and provides high availability andscaling using inexpensive DAS. You can run VDI-in-a-Box on two or more
servers and the grid automatically balances loads and ensures redundancy.
VDI-in-a-Box does not require organizational or cultural change
The intuitive management inter ace abstracts virtual ization details so desktopIT sta can set up and manage the solution without additional datacenter
expertise. Traditional VDI requires collaboration across storage, server, anddesktop IT teams.
With VDI-in-a-Box, you can start small and deploy in phases using
current budgetsVDI-in-a-Box runs on inexpensive commodity servers and you can start with
one or two servers and scale the deployment as needs grow. Since the uprontinvestment is minimal, you can use VDI-in-a-Box to prove that this solution
works and then scale incrementally.
VDI-in-a-Box has no centralized bottlenecks that cause boot storms
and other scaling issues in traditional VDIBy eliminating centralized bottlenecks such as separate connection servers,management servers and shared storage pools, the VDI-in-a-Box grid
architecture avoids issues such as boot storms that slow down traditionalVDI architectures.
Next, let us compare the shared-nothing model o Citrix VDI-in-a-Box with a
shared-VDI model such as VMware View.

Comparison: Citrix VDI-in-a-Box versus VMware View a shared-resources VDI solution
Component Cost
Shared-nothing VDI is ideal especially or customers needing a simple virtual desktopsolution such as Small and Medium Businesses (SMBs), educational institutions, stateand local government, and departments o enterprises. These customers are looking
or easy, cost-eective solutions that deliver demonstrable short-term ROI. The tablebelow compares the costs o deploying traditional VDI with VMware View versus next-
generation shared nothing VDI with Citrix VDI-in-a-Box. Access via repurposed PCsis assumed in both cases.
Notes on the table above
1. VMware View runs its management servers on Windows server OS and hence
you see additional line items or Management server and MS Server OS. This isan additional component compared to Citrix VDI-in-a-Box.
2. Even i VMware View (VDI sotware) were oered at no charge, Citrix VDI-in-a-Box
would still be cost eective because inrastructure accounts or the bulk o thecost o VMware VDI.
3. This comparison does not include the hardware, sotware and manpower costassociated with clustered SQL that VMware View requires.
VDI-in-a-Box costs less than 1/3 to deploy than View

How the two VDI solutions stack up against the topve business considerations
Traditional shared-resource VDI (VMware View) Shared-nothing VDI (Citrix VDI-in-a-Box)
Cost Traditional VDI solution needs management and provisioningservers, load balancers, connection brokers, shared SANstorage and specialty interconnects to deliver enterprise-grade virtual desktops. This requires signifcant uprontinvestment. Most organizations will need to deploy up toseveral hundred desktops beore theyll start to realize ROI.
See the various editions o VMware View 5 in Appendix C.Chances are high that you would need the higher pricedPremier product to get all the eatures that are required toprovide your end users highly available desktops.
Take a look at Appendix A and the component cost tableabove to better understand the upront cost o deploying
VMware View.Based on the table above, total cost per virtual desktopcomes to $1321 when you deploy a minimum o 100 virtualdesktops
The all-in-one design o Citrix-VDI-in-a-Box eliminates morethan 60% o VDI costs by cutting out the need or separateconnection brokers, provisioning servers, load balancers, orshared storage or high-availability.
Citrix VDI-in-a-Box runs on o-the-shel servers and canft within an existing PC reresh budget. VDI-in-a-Boxgenerates ROI with as ew as 25 desktops.
Citrix VDI-in-a-Box enables you to deploy virtual desktopsor less than the cost o PCs.
You can start as small as 25 virtual desktops and get eachvirtual desktop or less than the cost o a PC.
The minimum quantity o VDI-in-a-Box licenses is a10-pack.
Simplicity Traditional VDI has an extensive ootprint. You needspecialized expertise in storage and servers to deploy andmanage these solutions. Do not underestimate the complexityo VMware View architecture, particularly when used in aproduction environment. Youll need many servers to host abevy o management servers, provisioning servers, connectionbrokers and specialized sotware such as the Composerwhich provides storage optimization through the use o linkedclones. In addition to these servers, youll also need sharedstorage (SAN) and specialty interconnects.
In order to manage these sotware and hardware components,you would need administrators specializing in storage,networking and virtualization to collaborate.
Take a look at various components you would need toconfgure in order to produce the frst virtual desktop withVMware View 5 in Appendix B. Be sure to veriy whicheatures are built-in versus which eatures require customdeployment confguration.
See the VMware View 5 architecture diagram in Appendix Dand compare it to that o Citrix VDI-in-a-Box.
Now, think about amount o time it would take to get thewhole VDI solution up and running.
Purpose-built to deliver simple, aordable virtual desktops,VDI-in-a-Box bundles dynamic desktop provisioning, loadbalancing, high-availability, user management and desktopmanagement into a single virtual appliance.
To deliver the frst virtual desktop, all your Windowsadministrator needs to do is install the VDI-in-a-Box virtualappliance on an o-the-shel server.
VDI-in-a-Box uses inexpensive and easyto-manage DASinstead o expensive SAN.
Users connect via Citrix Receiver, a browser session or
a small Java client. Existing Ethernet is sufcient or anew deployment.
Take a look at Appendix D to compare and contrast thesearchitectures and to appreciate the simplicity o CitrixVDI-in-a-Box.
With Citrix VDI-in-a-Box, you can deliver the frstproduction-ready virtual desktop in less than an hour.
Scalability and
high availability
VMware View meets scalability and high availabilityrequirements but at a price: upront investment in a plethorao hardware components such as expensive shared storage
(SAN), connection brokers, load balancers, clustered SQLdatabases and sotware licenses.
Citrix VDI-in-a-Box meets scalability needs at an aordableprice. VDI-in-a-Box is ideal or phased deployments, withno rip-and-replace required. As you add more desktop
host servers to scale up, you will not encounter centralizedbottlenecks.
High availability is built into Citrix VDI-in-a-Box at no extracost. You dont need extra hardware, sotware or expensiveshared storage (SAN). Citrix VDI-in-a-Box uses direct-attached storage.
