If you haven't already caught on to using cloud computing, then you'd better move quickly because "mobile cloud
computing" is the current flavor.
Like any cloud computing, it is when the infrastructure - the data
storage and the data processing - happen outside of the (mobile) device.
If you are using applications like
Gmail, Google Maps, and Google Documents, then you are using cloud computing whether you do it on your laptop, desktop
or mobile device. In the mobile world, there are still many (a majority?) of applications that do most of the data
storage and processing on the mobile devices itself and not in the cloud.
The term "cloud" is used
as a metaphor for the Internet. In computer network diagrams, the Net is depicted in the shape of a cloud. Installing
Microsoft Office on your computer and storing your documents, spreadsheets, databases and PowerPoints on your hard drive
is NOT cloud computing.
What is so appealing about using the cloud? For one thing, as a user, you do not need
knowledge of, expertise in, or control over the technology infrastructure about the cloud network you are using. If you
use those Google applications, then Google is your IT department. They handle the updates, backups and emergencies.
Users also like that they can move from computer to computer (home, office, on the road, another classroom location) and
all their data is waiting for them - not on a flashdrive or disk (Does anyone use those any more?) - in the cloud.
That cloud might include infrastructure as a service (IaaS), the platform as a service (PaaS - ex: Salesforce,
Amazon Web Services), or, most commonly for the average user, software as a service (SaaS).
More people are
purchasing lightweight netbook computers and also keeping the software load on the computer light by using software in
the cloud.
I store all my personal bookmarks in the cloud using
Xmarks which works with Firefox, Safari and Internet Explorer. The
service automatically syncs up any changes I make to my bookmarks so that what I have on my home computer is also
available on my work computer. A few years ago, I would have copied the bookmarks file and then "tried" to
copy them over to another computer. Very difficult to "synchronize." When I bought a new laptop recently, I
just added the Xmarks plug-in and clicked sync and all my bookmarks were there.
Tech pundits (see link at
bottom) are saying that cloud computing will become a disruptive force in the mobile world.
Why? First, the
sheer number of users it can reach. Second, mobile applications are currently tied to a carrier. Want an iPhone or
Blackberry app? You need a relationship with the mobile operator who carries the iPhone or Blackberry. But with mobile
cloud applications, all you need is access to the web to use the application. (see
Google Android?)
The
first mobile cloud apps will probably be business-focused, but big education players (like Blackboard) are already
showing their mobile apps for collaboration, data sharing, multitasking, scheduling and even navigation and mapping for
your campus.
So, the cloud is the place to be, right? Well, there are some problems or poetential problems.
Not everyone has a smart featurephone. Not everyone or everywhere has really fast mobile Internet access. The U.S. is
behind in its 3G coverage outside urban areas. And what happens to all your data (like your presentation, class notes
and your thesis) when you can't get online? Do you trust Google to protect your data?
Maybe new technologies,
like
HTML5 which does local caching, will
help. Some pundits predict we may end up accessing the web on mobile devices with something other than a
"browser."
Friends of mine know that I am not a big mobile user and definitely not a smartphone
user. But I keep up with the trends, particularly in education. I was talking last week with some educators at a
conference at UCONN and pointed out that many of the better practices I encounter come from business, not education.
Take this case study on "
Making the Transition to a Virtual Classroom in the Cloud" by Christine Mikolajczak. It's not
from a school, but from
ASTD
-
the American
Society for Training & Development, the "world’s largest
association dedicated to workplace learning and performance
professionals."
I wonder how her four goals would fit those of your classroom - or the goals of
your administration...
1. offer a remote training option for learners who could not travel on-site
2. create a new delivery option for end users
3. reduce operating and maintenance costs
on a per class basis
4. launch the new program within 30 days.
I am not saying that we
should necessarily be looking at the same stand-alone virtualization platforms and distance learning tools, (They used
Skytap’s Virtual Lab in the cloud in
this case) but we should be looking at what they are doing and how they are doing it.
I learned when I was
the manager of instructional technology at NJIT and we created distance learning products for non-educational clients,
that accountability, return on investment and adherence to standards (like
SCORM) were taken far more seriously outside academia. In her case study, they
accomplished "all of our objectives with a limited budget" launched a new training program "in record
time" had "learners [are] excited about using the new solution," and they were "able to lower our
tuition rates by 66 percent."
Wow. Call the provost.
