Slide 4: 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. miklos.biro Business Drivers and Challenges of Cloud Computing and Social Networking Application Development 4

Slide 7:  Larry Ellison Oracle’s chief executive (The Wall Street Journal 09/25/2008): What is Cloud Computing? 2 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://www.youtube.com/watch?v=0FacYAI6DY0 – ―The interesting thing about cloud computing is that we’ve redefined  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.‖ miklos.biro Business Drivers and Challenges of Cloud Computing and Social Networking Application Development 7

Slide 10: 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 Business Drivers and Challenges of Cloud Computing and Social Networking Application Development 10 miklos.biro

Slide 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.  How Cloud & SaaS Will Change IT in 2010, and How it Won‘t http://www.avanade.com/people/thought_de tail.aspx?id=79 miklos.biro Business Drivers and Challenges of Cloud Computing and Social Networking Application Development 12

Slide 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. miklos.biro Business Drivers and Challenges of Cloud Computing and Social Networking Application Development 25

Slide 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 and Social Networking Application Development 37
Slide 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  If you want to take part in the experience, visit the following web page, and always follow the yellow brick road http://rex.uni-corvinus.hu/mbiro/joinusv07/ Business Drivers and Challenges of Cloud Computing and Social Networking Application Development 38 miklos.biro
