COURSE PREREQUISITE: Object-Oriented Programming and Design skills. Moderate understanding of computer architecture and of operating systems. Moderate understanding of distributed computing 3. COURSE OBJECTIVE: What are the risks associated with the SOA approach What are the trade-offs How to assess potential profit with SOA What real business case studies has been already made When and to what extent SOA should be implemented What are simplification and decomposition benefits How to migrate from existing solutions to SOA and why migration to SOA does NOT require rebuilding the whole existing infrastructure How to extend legacy applications with SOA What are the existing SOA suites and platforms

How can you achieve loose coupling in a soa? 6. Do you recall any pattern which could be use to leverage loose coupling? 7. What is composition of a Service? 8. How do I integrate my Legacy applications with SOA? 9. How does the ESB fits in this picture? 10. What are the common pitfalls of SOA? 11. What's the difference between services and components? 12. What are ends, contract, address, and bindings? 13. The concept of SOA is nothing new, however why everyone started to talk about SOA only in the last years? 14. What is the most important skill you need to adopt SOA? technical or cultural? 15. Is SOA really needed on your opinion? 16. Why there is need to concrete and abstract wsdl? 17. Correlation vs WS-addressing? 18. What is the difference between Async and Sync activity on wsdl level? 19. What is structure of SOAP message? 20. Why do we need to have messages in WSDL, aren't operations and types enough to describe the parameters for a web service? 21. What is forward delay in JMS Queue? 22. What is redelivery limit in JMS Queue? 23. Difference between JMS Queues and Topics? 24. While identifying services which one is better top-down and bottom-up methodologies encourages re-use and maintenance? 25. Do you recall any pattern which could be use to leverage loose coupling? 26. How do I integrate my Legacy applications with SOA? 27. Explain in detail the business layers and plumbing layers in SOA, if possible with an example. Page 7 of 7
