  1. Service-Oriented ArchitectureAn Agent of Change? Huy Pham

  2. Before we start… • Why a social and business focus? • Not because I am a business person • Found some questions that might be of interest to you • Most of you know more about SOA and WS than I do • Spent the last 6 years trying to become a roboticist! • Not a one-way presentation: • A group discussion • A radio pod-cast, if you like!  Your participation is needed!

  3. Agenda • Technical summarization of SOA and WS • An Agent of Changes • How SOA and WS can be useful in addressing the problems of this ever-changing world • And how they create the new kind of changes themselves • Fears/Opportunities • What can we, the techies, do to ride/survive these waves of changes It's a disscussion, remember?

  4. SOA and WS • What are they? • What are they good for?

  5. Change – The technical challenge • “The only constant is change” • Types of change: • Personnel • Requirements • Development and Deployment Platform • Organizational Restructuring • Cannot be ignored • Point solutions are no longer useful • The dire need of Robustness

  6. SOA as a technical answer • A universal connection technology • The PCI bus in the PC • The RCA connectors in A/V equipments • Services are independent and replaceable system components •  Modularity  Reuse: From class level to service level  Robustness: Quicker response to changes

  7. Change – The social challenge • How well can you live with change? • Different people have different tolerance • The same person would have different response in different situations • In all cases, change can be very unpleasant! • Especially when we are unprepared  Be prepared!

  8. SOA as the • SOA is an agent of changes for the IT industry • Large-scale yet robust systems will be built in modular ways using standardized services • Organizations will buy standardized software packages instead of building custom ones • The employment market for software developers will not remain the same • If you are not prepared for the changes, SOA can become a fear factor!

  9. How do we prepare?

  10. A visit to The Oracle • “The world won’t change overnight – Thy shall make a fortune adapting the existing systems to the new standard” • “Thy shall not find entry-level development jobs, but shall find highly skilled jobs with ISVs that cater services to specific industries” • “In both cases, thy shall learn about the transitional stages”

  11. Expected Transition Stages • Experiment with Web Services • Organizations send people for training, hire new people with the required knowledge • Adapting existing systems to WS • Continue training and hiring process • Building enterprise-wide SOA infrastructures • Integrating with industry-wide systems

  12. Conclusions • As a universal connection technology, SOA: • Helps solve the scalability and robustness problem of enterprise information systems • Make the IT industry a better place for those who are prepared • Thank you for your participation! • I am eager to have more discussions!
