Business Driversaddressed 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?

2 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.‖

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

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.

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.

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.

Example Scenario

Zero Code Contribution 1

The FollowUs message wall is obtained by omitting the yellow items!

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.

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
