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 Oracles chief executive (The Wall Street Journal 09/25/2008):

The interesting thing about cloud computing is that weve redefinedcloud computing to include everything that we already do. I cant think

of anything that isnt cloud computing with all of these

announcements. The computer industry is the only industry that is

more fashion-driven than womens fashion. Maybe Im an idiot, but I

have no idea what anyone is talking about. What is it? Its complete

gibberish. Its insane. When is this idiocy going to stop?

Well make cloud computing announcements. Im not going to fight

this thing. But I dont understand what we would do differently in the

light of cloud computing other than change the wording of some of our

ads. Thats 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 digitaltechnology 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 Technologies2009 (Gartner)


13/43

Analysis by Gartner Cloud Computing. The levels ofhype around cloud

computing in the IT industry are deafening, with every

vendor expounding its cloud strategy and variations,

such as private cloud computing and hybrid approaches,

compounding the hype.

Social Software Suites. Disillusionment is beginningbased on the realization that, even with a suite, much

work must be done to build an effective social software

deployment.

Microblogging. Microblogging, in general, and Twitter,in particular, have exploded in popularity during 2009 to

the extent that the inevitable disillusionment around

"channel pollution" is beginning

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

threefold in the nine months since the lastsurvey was conducted. During the same periodof 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. How Cloud & SaaS Will Change IT in 2010,

and How it Wont

Letter from the Editors (December 2009)It is hard to believe thatjust seven short months ago, we pulled

together a diverse group of individuals from all corners of the

technology industry to publish the first Security Guidance for

Critical Areas in Cloud Computing. Since its launch, this seminal

publication has continued to exceed our expectations for helping

organizations around the world make informed decisions regarding if,

when, and how they will adopt Cloud Computing services and

technologies. But over those seven months our knowledge, and

cloud computing technologies, have evolved at an astounding rate.This second version is designed to provide both new knowledge and

greater depth to support these challenging decisions.

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

speakers prompts from their laptop, PDA, or smart phone.

All feedback should be immediately visible and persistently stored.

Not feasible without cloud computing.

Conclusion 1

The presentation gave an overview of the

business drivers for the application ofstrategic

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 andstill 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
