In this talk I discussed the role of SOA and open source technology in building large scale distributed systems for national defence and regional cooperation. My primary objective was to encourage collaboration in the form of FOSS and open standards to make better software systems for a given military organization or for groups of friendly nations.

7. Open source and its implications

8. Open standards

9. Interoperability framework for net centric operations

10. US DoD SOA activities

11. Open source SOA for defence applications

12. Summary

15. Service metadata is often registered for easy discovery and governance

16. SOA?

17. Typical business SOA picture

22. Try before you buy

23. Lower cost of entry

24. Better security

26. Everything from server/desktop/embedded system operating systems to all middleware to desktop apps to enterprise apps

30. Closed-source SOA products are complex, non-agile and expensive

31. Deployment of SOA always requires a lot of customization

34. Open standard means has wide adoption and support

35. Critical for long term data protection

36. Critical for interoperability between friendly nations

39. Use of interoperable message protocols and standards

41. SOA in an SOA (in an SOA ...) MoD MoD Common Services Navy

43. Scalable authentication

44. Fine grained authorization

46. End-to-end security is now possible

50. Incredible amount of legacy to deal with

54. Promote early and continuous collaboration among all stakeholder (e.g., developers, material providers, testers, operators, and users) throughout the development life-cycle

55. Rapidly deliver effective and efficient development and test capabilities for DoD technology development efforts

56. Help protect the operational environment from potentially harmful systems and services

57. Encourage modularity so that large programs to be developed, fielded, and operated as a set of independent components that can evolve and mature at their own rates

61. Opportunity to leapfrog!

65. Make military software technology a strategic weapon for the country & allies

67. SOA enables scalable, strategic sharing of information in net centric operations

68. Free & Open Source Software (FOSS) provides a superb platform for building SOA solutions

69. FOSS provides intrinsic strategic advantages to the country
