[Biro M, 2009] Business Drivers and Challenges of Cloud Computing and Social Networking Application Development. In Proceedings of the IFIP TC8 WG8.9 International Conference on Research and Practical Issues of Enterprise Information Systems (CONFENIS 2009) (ed. by M. Raffai) - Abstract: This presentation addresses those business and academic audiences who are not developers, but who are highly responsive to the new opportunities offered by the rapidly changing software and hardware technology.
Following the overview of the business drivers and of the architectural requirements of the subject area, we actually develop within a few minutes the social software the audience can use during the presentation itself to experience its effect.

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.

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.‖

(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.‖

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)

– 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

12. 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.

25. 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.

32. 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.

37. 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.
miklos.biro Business Drivers and Challenges of Cloud Computing
37
and Social Networking Application Development
38. 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
