Business Drivers
addressed by this presentation

 Interactive problem solving, not merely information access.
 Cost reduction through economies of scale involving ICT as a
public utility.
 Flexibility in the deployment of new technologies.
 Scalability in case of unexpectedly growing demand using server
farms.
 Availability secured by load balancing.
 Maintainability, knowing that maintenance cost can customarily
exceed 75% of the total software development life-cycle cost.

What is Cloud Computing?


Larry Ellison Oracle’s chief executive (The Wall Street Journal 09/25/2008):
– ―The interesting thing about cloud computing is that we’ve redefined
cloud computing to include everything that we already do. I can’t think
of anything that isn’t cloud computing with all of these
announcements. The computer industry is the only industry that is
more fashion-driven than women’s fashion. Maybe I’m an idiot, but I
have no idea what anyone is talking about. What is it? It’s complete
gibberish. It’s insane. When is this idiocy going to stop?‖
―We’ll make cloud computing announcements. I’m not going to fight
this thing. But I don’t understand what we would do differently in the
light of cloud computing other than change the wording of some of our
ads. That’s my view.‖

 http://online.wsj.com/article/SB124580329161844787.html
(The Wall Street Journal 07/23/2009):
– ―Oracle Corp. Chief Executive Larry Ellison appears to be rethinking
"cloud computing”, saying his company was creeping into the space just
nine months after he mocked the business model.‖

Business Drivers
 http://www.economist.com/specialreports/displayStory.cfm?story_id=12411882

Inflated expectations:

„The rise of the cloud is more than just another platform shift that gets geeks excited. It
will undoubtedly transform the information technology (IT) industry, but it will also
profoundly change the way people work and companies operate. It will allow digital
technology to penetrate every nook and cranny of the economy and of society, creating
some tricky political problems along the way.‖ (The Economist Oct 23rd 2008)
 http://www.avanade.com/people/thought_detail.aspx?id=79
– What SaaS means for businesses:
 Increased business ―operational elasticity‖
 Faster time-to-market, easier to enter or exit new markets
 IT cost reduction, shift focus to strategic, vs. maintenance related efforts
 Increased connection, collaboration with customers, partners, suppliers and
others

Hype Cycle for Emerging Technologies

Are we heading to a trough of
disillusionment?
 Global Survey of Cloud Computing
September 2009
 Despite the global recession and a keen focus
on cost savings, the rate of respondents
reporting that they are beginning to plan or
test cloud computing has increased
three‐fold in the nine months since the last
survey was conducted. During the same period
of time, companies reporting no plans to adopt
cloud computing declined from 54 percent to
37 percent. The gap between those with
plans and trials, and those with no plans to
adopt, is shrinking dramatically.

and How it Won‘t

It is loose coupling between the tiers
which allows the well maintainable
zero or minimal code development in
the Visual Studio® IDE

illustrated by the following example.

24

Example Scenario
Contribution to a Presentation
 Context:
– A presentation during which the speaker would like to receive immediate
feedback from the participants whose list is known in advance.
– Usual in a classroom, conference, or large convention where there is never
opportunity for more than a few comments form the audience.
 Input:
– The list of participants in a simple Excel table imported into Access.
 Requirements:
– Allow all locally present or remote participants to give feedback to the
speaker’s prompts from their laptop, PDA, or smart phone.
– All feedback should be immediately visible and persistently stored.

Not feasible without cloud computing.

Call for Contribution

Is there any
emerging further requirement
you find necessary to satisfy
?

30

Loose coupling with zero code
in the example

 Data tier: Access database
 Presentation tier: Design view (default.aspx)
 Business logic: Events handled in code behind (default.aspx.cs)

31

Extension of the Scenario
Join Us in Person
 Context:
– We would like to offer our remote audience to join us in person.
 Input:
– The current location of a remote participant.
 Requirements:
– Provide guidance to the remote participant to get to our location:
 Follow the yellow brick road! 

 Idea:
– Experiment with an external web service which can be consumed from our
code behind using very few lines of code with loose coupling.

Conclusion 1
 The presentation gave an overview of the
business drivers for the application of strategic
technologies in 2009 and 2010 which result in
the rise of cloud computing among others.
 The zero code development of a social
application is illustrated on a scenario providing
an initiating experience of the potential of a very
simple social software accessible in the cloud.

37

Conclusion 2
 The satisfaction of further requirements leads to the
consumption of web services with very little code and
still loose coupling illustrating at least four of the ten
strategic technologies for 2009 and 2010 listed by Gartner:
– Cloud Computing.
– Web-Oriented Architectures.
– Social Software and Networking.
– Mobile Applications

following web page, and always
follow the yellow brick road
