Dana Gardner: Hi. This is Dana Gardner, Principal Analyst at Interarbor Solutions, and you’re
listening to BriefingsDirect.
Today, we present a sponsored podcast discussion on how enterprises are increasing their use of
desktop virtualization in the post-PC era. We’ll also learn about the new
phenomena of "bring your own device" (BYOD) and explore how IT
organizations are enabling users to choose their own client devices, yet still
gain access to all the work or learning applications and data they need safely,
securely, and with high performance. [Disclosure: VMware is a sponsor of
BriefingsDirect podcasts.]
The nice thing about BYOD is that you can essentially extend what do you do
on premises or on a local area network (LAN) to anywhere, to your home, to your travels, 24×7.
The Avon Community School Corporation at Avon, Indiana has been experimenting with BYOD
and desktop virtualization, and has recently embarked in a wider deployment for both for the
2011-2012 school year. We’re about to hear their story.
So please join me now in welcoming our guests -- Jason Brames, Assistant Director of
Technology at Avon Community School. Welcome, Jason.
Jason Brames: Hello. Great to be here.
Gardner: We’re also here with Jason Lantz. He is the Network Services Team Leader there at
Avon. Welcome, Jason Lantz.
Jason Lantz: Hello.
Gardner: Let’s start with you, Jason Brames. It sounds like you've been successful with server
virtualization over the past couple of years with roughly 80 percent virtualization rate on those
backend systems. What made it important for you now to extend virtualization to the desktop?
Why has this become an end-to-end value for you?
Brames: One of the things that is important to our district we noticed when doing an assessment
of our infrastructure. We have aging endpoints. We had a need to extend the refresh rate of our

2. desktop computers from what was typical -- for a lot of school districts typical is about a 5-year
refresh rate -- to getting anywhere from 7 to 10, maybe even 12 years, out of a
desktop computer.
By going to a thin client model and connecting those machines to a virtual
desktop, we're able to achieve high quality results for our end users, while still
giving them computing power that they need and allowing us to have the cost
savings by negating the need to purchase new equipment every five years.
Gardner: So even though those PCs have 150,000 miles so to speak, you can
keep them going and keep them running for another couple of years.
Brames: Yeah, and most importantly, providing that quality of service and computing power that
the end user has grown accustomed to.
Gardner: Tell us a little bit, Jason, about Avon Community School Corporation, the grades, your
size, what sort of organization are you?
Supporting 5,500 computers
Brames: We're located about 12 miles west of Indianapolis, Indiana, and we have 13
instructional buildings. We're a pre-K-to-12 institution and we have approximately 8,700
students, nearing 10,000 end-users in total. We’re currently supporting about 5,500 computers in
our district.
Gardner: That’s a large number. What was the problem you needed to solve when you were
looking at this large number of devices and a large number of users? I assume that you probably
want to get an even higher penetration of device per user.
Brames: Absolutely. By going with virtual environment, the problem that we were looking to
solve was really just that -- how do we provide extended refresh rate for all of those devices?
Gardner: What I was driving at was not just the numbers but the ability to manage that. So the
complexity and cost, was that part of the equation as well?
Lantz: As you said, with that many devices, getting out there and installing software, even if it’s
a push, locally, or what have you, there's a big management overhead there. By
using VMware View and having that in our data center, where we can control
that, the ability to have your golden image that you can then push out to a
number of devices has made it a lot easier to transition to this type of model.
We’re finding that we can get applications out quicker with more quality control,
as far as knowing exactly what’s going to happen inside of the virtual machine
(VM) when you run that application. So that’s been a big help.

3. Gardner: And we’re talking about not just productivity apps here, I assume. We’ve got custom
apps, educational apps, and I'm going to guess probably a lot of video and rich media.
Lantz: A lot of our applications are Web-based, Education City, some of those. It’s a lot of
graphics and video. And we found that we're still able to run those in our View environment and
not have issues.
Gardner: Why don’t you tell us a little bit about your environment? What are you running in
terms of servers? What is your desktop virtualization platform, and what is it that allows you to
move on this so far?
Lantz: On the server side, we're running VMware vSphere 4.1. On the desktop side, we're
running View 4.6. Currently in our server production, as we call it, we have three servers. And
we're adding a fourth shortly. On the View side of things, we currently have two servers and
we’re getting two more in the next month or so. So we’ll have a total of four.
Access from anywhere
Gardner: Now one of the nice things about the desktop virtualization and this BYOD is it
allows people to access these activities more freely anywhere. My
kids are used to being able to access anything. If you were to tell
them you can only do school work in school, they'd look at you like
you’re from another planet.
So how do you manage to now take what was once confined to the school network and allow the
students and other folks in your community to do what they need to do, regardless of where they
are, regardless of the device?
Brames: We’re a fairly affluent community. We have kids who were requesting to bring in their
own devices. We felt as though encouraging that model in our district was something that would
help students continue to use computers that were familiar to them and help us realize some cost
savings long term.
So by connecting to virtual desktops in our environment, they get a familiar resource while
they're within our walls in the school district, have access to all of their shared drives, network
drives, network applications, all of the typical resources that are an expectation of sitting down in
front of a school-owned piece of equipment. And they're seeing the availability of all of those
things on their own device.
We’re also seeing an influx of more mobile-type devices such as tablets and even smartphones
and things like that. The percentage of our users that are using tablets and smartphones right now
for powerful computing or their primary devices is fairly low. However, we anticipate over time
that the variety of devices we’ll have connecting to our network because of virtual desktops is
going to increase.

4. Gardner: Jason Lantz, are you at the point where you're able to extend the same experience for
those students who would be in school using a PC, getting all of mileage out of that that they
can, saving you guys a few dollars in the process, but then move over to their own device, let’s
call it a tablet, and start right into the same session? How is that handoff happening? Are you
there able to segue and provide a unified experience yet?
Lantz: That’s part of phase two of our approach that we’re implementing right now. We’ve
gotten it out into the classrooms to get the students familiar with it, so that they understand how
to use it. The next step in that process is to allow them to use this at home.
We currently have administrators that are using it in this fashion. They have tablets and are using
the View client they connect in and get the same experience if they're in school or out of school.
So we’re to that point. Now that our administrators understand the benefits, now that our teachers
have seen it in the classrooms, it’s a matter of getting it out there to the community.
One of the other ways that we’re making it available is that at our public library, we have a set of
machines that students can access as well, because as you know, not every student has access to
high-speed Internet, but they are able to go to library, check out these machines, and be able to
get into the network that way. Those are some of the ways that we’re trying to bridge that gap.
Huge win-win
Gardner: It sounds like a huge win-win, because you’re able to reduce your costs, increase
your control, and at the same time give the students a lifecycle of learning across all of the
different devices and places that they might be. I think that’s fabulous.
Let's find out a bit more about how far into this you are. Jason Brames, you mentioned that you
have about 5,500 devices endpoints. How far into that number are you with desktop
virtualization? Then, maybe you can give us a sense of how many BYOD instances you have
too?
Brames: Currently have 400 View desktop licenses. We’re seeing utilization of that license pool
of 20-25 percent right now, and the primary reason that we’re seeing that utilization is because
we’re really just beginning that phase, with this being our first year for our virtual desktop roll
out. We’re really in the second year, but the first year of more widespread use.
We’re training teachers on how to adequately and effectively use this technology in their
classroom with kids It's been very highly received and is being adopted very well in our
classrooms, because people are seeing that we were able to improve the computing experience
for them.

5. Gardner: I understand that you’ve had a partner involved with this. TIG I believe it is. How did
that affect your ability to roll this out so far?
Lantz: Technology Integration Group has resources that allow us to see what other school
districts are doing and what are some of the things that they’ve run into. Then, they bring back
here and we can discuss how we want to roll it out in our environment. They’ve been very good
at giving us ideas of what has worked with other organizations and what hasn’t. That’s where
they've come in. They’ve really helped us understand how we can best use this in our
environment.
Gardner: Sometimes I hear from organizations, when they move to desktop virtualization, that
there are some impacts on things like network or storage that they didn’t fully anticipate. How
has that worked for you? How has this roll out movement towards increased desktop
virtualization impacted you in terms of what you needed to do with your overall infrastructure?
Lantz: Luckily for us we’ve had a lot of growth in the last two to three years, which has allowed
us to get some newer equipment. So our network infrastructure is very sound. We didn’t run into
a lot of the issues that commonly you would with network bandwidth and things like that.
On the storage side, we did increase our storage. We went with an EqualLogic box for that, but
with View, it doesn’t take up a ton of storage space with link clones and things like that. So
having seen a huge impact there, now as we get further into this, storage requirements will get
greater, but currently that hasn’t been a big issue for us.
Gardner: On the flip-side of that, a lot of organizations I talk to, who moved to desktop
virtualization, gained some benefits on things like backup, disaster recovery, security, and control
over data and assets, and even into compliance and regulatory issues. Has there been an upside
that you could point to in terms of being a more centralized control of the desktop content and
assets?
Difficult to monitor
Lantz: When you start talking about students bringing in their own devices, it's difficult to
monitor what's on that personally owned device. You can use appliances like Mac and things like
that.
We found that by giving them a View desktop, we know what's in our environment and we know
what that virtual machine has. That allows us to have more secure access for those students
without compromising what's on that student’s machine, or what you may not know about what's
on that student’s machine. That’s been a big benefit for us allowing students to bring in their own
devices.

6. Gardner: Otherwise you’re bringing something onto your networks that you really don’t know
what's there, and lose control. This allows you to have that best of both worlds flexibility at some
appreciation of how to keep your risks low.
Lantz: Absolutely.
Gardner: Do we have any metrics of success either in business or, in this case, learning terms
and/or IT cost savings? What has this done for you? I know it's a little early, but what's the early
results?
Brames: You did mention that it is a little bit early, but we believe that as we begin using virtual
desktops more so in our environment, one of the major cost savings that we’re going to see as a
result is licensing cost for unique learning applications.
Typically in our district we would have purchased x number of licenses for each one of our
instructional buildings because they needed to utilize that with students in the classroom. They
may have a certain number of students that need access to this application, for example, but
they're not all accessing it during the same time of the day or it's on a machine that’s on a fat
client, a physical machine somewhere in the building, and it's difficult for students to have access
to it.
By creating these pools of machines that have specialty software on them we’re able to
significantly reduce the number of titles we need to license for certain learning applications or
certain applications that improve efficiencies for teachers and for students.
So that’s one area in which we know we’re going to see significant return on our investment. We
already talked about extending the endpoints, and with energy savings, I think we can prove
some results there as well. Anything to add, Jason?
Lantz: One of the ones that’s hard to calculate is, as you mentioned, maintenance or
management of this piece and technology, as we all know you’re doing more with less. This
really gives you the ability to do that. How you measure that is sometimes difficult, but there are
definitely cost savings there as well.
Gardner: Just to be clear, the folks that are adopting this first in your organization, are these the
students, are they folks in a lab, a research environment, faculty? Who are the people that grok
this and really jump on it first?
No lab deployment
Brames: The first place where we’re deploying are the student computing stations in our
classrooms. We’re not deploying to lab environments as much as we are to those locations in our
classrooms.

7. A typical classroom for us contains four student computing stations, as well as, depending upon
the building size, three to five labs available. We’re not focusing our desktop virtualization on
those labs. We’re focusing on the classroom computing stations right now. Potentially, we'll also
be in labs, as we go into the future.
Then, in addition to those student computing stations, we’re seeing those applications where our
administrative team or principals and our district-level administrators are able to begin using
virtual desktops to access while they’re outside of the district and growing familiar with that, so
that whenever we enter into that phase where we’re allowing our students to access from outside
of our network, we have that support structure in place.
Gardner: That sounds important especially for those later grades and high school grades,
because this is probably the type of experience they’re going to be getting should they move onto
college, where they are going to each have a device and have this ubiquity. It seems to me that
they'll be one step ahead, if they get used to that now in high school. Even junior high school sets
them up to be more productive and adapted to what they'll get in a college environment.
Lantz: In a lot of organizations, it would make sense to start there. With their higher level,
they're going to be able to use it outside the districts probably more than the elementaries. But
for us, it made sense with our older hardware. It’s primarily in a lot of our elementaries, middle
schools, and intermediates. So it made sense that that’s where we would start.
Gardner: I know budgets are really important in just about any school environment. If you were
to say, "Listen, the cost it would take for us to make sure each individual student had their own
device would be X and the cost of supporting it would be additional each year," you might get
some pushback. I'm going to make a wild guess on that.
But it sounds to me like you’re able to go with desktop virtualization and increased use of
BYOD and say, "Listen, we can get to near one-to-one parity with student to device for a lot
less."
Do you have any sense of the delta there between what it would be if you stuck to traditional cost
structures, traditional licensing, fat client, to get to that one to one ratio, compared to what you’re
going to be able to do over time with this virtualized approach? Any sense of how big a delta that
we have there?
Brames: Our finance department has been very supportive of us in this whole endeavor, and the
return on investment (ROI) cost calculations and everything is something that our finance team is
very good at. We appreciate that they were able to recognize with us that this is something that
would be beneficial to the district.
I apologize that I'm not actually prepared to put any numbers on it. Because we're early, putting
an actual number is challenging for me right now.

8. Metrics of success
Gardner: Jason Lantz, I know actual numbers are dollars, but do you have any sense of maybe
a percentage or even just a generalization of what the comparison between the old way of getting
the one to one versus the new ways?
Lantz: It's little bit difficult. In our Advanced Learning Center -- and Jason, you can help me out
with this -- as far as student-owned devices versus people bringing in their own devices, do you
know what those numbers would be?
Brames: Advanced Learning Center is the school building that has primarily senior students and
advanced placement students. There are about 600 students that attend there.
Last year, 75 percent of those students were using school-owned equipment and 25 percent of
them were bringing their own laptops to school. This year, what we have seen is that 43 percent
of our students are beginning to bring their own devices to connect to our network and have
access to network resources.
If that trend continues, which we think it will, we’ll be looking at certainly over 50 percent next
year, hopefully approaching 60-65 percent of our students bringing their own devices. When you
consider that that is approximately 400 devices that the school district did not need to invest in,
that’s a significant saving for us.
Gardner: That’s a very rapid growth rate, and so you've been able to accommodate that. But
you’re going from 25 percent to 43 percent and you’re certainly not seeing that uptake in terms
of your total cost. So it’s a saving on significant basis.
Brames: It is a little bit of a small snapshot right now. Our senior center has seen this increase,
and district-wide we think that our results can be projected to our K-12 grade levels over time.
Gardner: I commend you for being able to anticipate and accommodate these trends, because
this is happening so rapidly with these devices.
One last set of questions on advice for others who would be moving towards more desktop
virtualization and the enablement of BYOD. If you could do this over again, a little bit of 20/20
hindsight, what might you want to tell them in terms of being prepared?
Lantz: One thing that’s important is that when you explain this to users, the words "virtual
desktop" can be a little confusing to teachers and your end-users. What I've done is taken the
approach of it’s no different than having a regular machine and you can set it up to where it looks
exactly the same.

9. No real difference
When you start talking with end users about virtual, it gets into, okay, "So it’s running back
here, but what problems am I going to encounter?" and those sort of things. Trying to get that
end user to realize that there really isn’t a difference between a virtual desktop and a real desktop
has been important for us for getting them on board and making them understand that it’s not
going to be a huge change for them.
Gardner: Over time, as it becomes seamless, they wouldn’t really know. They just log in based
on their password and ID and then the things just work.
Lantz: Yeah.
Brames: Yeah, I think so.
Gardner: Very good. You’ve been listening to a sponsored podcast discussion on how
enterprises and in this case, a learning group are increasing their use of desktop virtualization in
the post-PC era. And they’re also very much on top of a new phenomenon around "bring your
own device."
