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.

    • Agenda
      • SOA & its implications
      • Open source and its implications
      • Open standards
      • Interoperability framework for net centric operations
      • US DoD SOA activities
      • Open source SOA for defence applications
      • Summary
    • What is SOA?
      • An approach for building large scale systems where functionality is bundled as interoperable “services”
        • Details of how the service is implemented are not important
        • Consumer operates against a service contract that defines the business interface and qualities of service
      • Services interact with each other by sending messages in an interoperable standard
      • Service metadata is often registered for easy discovery and governance
    • SOA?
    • Typical business SOA picture
    • SOA in Sri Lanka government: LankaGate Other Applications Services Providers Open Standards SOA Architecture Enabling Web 2.0 Concepts Mobile Payment Gateway Other portlets Lanka Interoperability Exchange Citizens Businesses Visitors Government Multiple Access Channels (eg. Web, Mobile, Email, etc.) Identity Mgt. CMS portlet GIC portlet e-Gov Service 1 portlet e-Gov Service m portlet Services Directory Service 1 (eg. e-RL) Service n
    • Advantages of SOA
      • Localized management of information and data
        • (Think of object orientation taken to the next level)
      • Decentralized deployment
        • Owner of information runs the service that exposes the data
      • 100% securable
        • Complete security platform available
      • Total focus on interoperability
        • While maintaining proper authentication & authorization
      • Open-ended, decentralized customization and localization
        • Scalable for a single country or a coalition
    • Open source
      • Open source fundamentally about source code being available
        • Under license terms that allow you to improve & redistribute
      • Collaborative development paradigm
        • Enabled by the Internet
      • Does not necessarily mean free of charge
        • Support often costs money
      • “Free software” vs. “open source software”
        • Free & open source software (FOSS)
    • Advantages of FOSS
      • Freedom to innovate
      • Try before you buy
      • Lower cost of entry
      • Better security
    • FOSS software?
      • Anything !
      • Everything from server/desktop/embedded system operating systems to all middleware to desktop apps to enterprise apps
      • Very often FOSS builds on other FOSS
        • Standing on the shoulders of giants
        • Culture of easy license-compatible dependency taking
      • EVERY software vendor now has FOSS in some form, inside or shipping
        • No longer a niche concept
    • FOSS & SOA
      • “You can't buy SOA, you have to build it”
      • Closed-source SOA products are complex, non-agile and expensive
      • Deployment of SOA always requires a lot of customization
      • Especially in military context, does not provide the framework for the military organization to take control of the software
        • Build local skill and knowledge and reduce external dependency
      • Opportunity to “fork”
    • Open standards
      • Standards are critical for interoperability
      • Open standard means has wide adoption and support
      • Critical for long term data protection
      • Critical for interoperability between friendly nations
    • Interoperability framework vs. architecture framework for net centric operations
      • Traditional thinking on building large scale systems is to have an architecture framework
      • Does not provide sufficient room for innovation within local contexts
        • “Local” can range from national level to different military branches to different parts of a single organization
      • Key criteria is interoperability
        • Documented data standards
        • Use of interoperable message protocols and standards
        • Use of interoperable security protocols and standards
      • Opportunity to share code across units, branches, nations
    • SOA in an SOA (in an SOA ...) MoD MoD Common Services Navy
    • Security in SOA
      • SOA technology platform provides complete security story
        • Message level security
        • Scalable authentication
        • Fine grained authorization
        • Audit / Non-repudiation
      • Even enemies can share the same technology platform and use policy driven security to ensure proper access and protection
      • End-to-end security is now possible
    • US DoD SOA activities
      • DoD Net Centric Enterprise Services (NCES)
        • Common services for the DoD
        • SOA platform
      • SOA Symposium in Washington, DC in March
        • 500+ attendees from all branches of military – CIOs, senior IT officers
        • Focused on education of SOA concepts
      • Very large complex problem for US DoD
        • 3.5m people in organization
        • Incredible amount of legacy to deal with
        • Complex procurement processes that are inherently designed around enterprise systems
          • (Which have repeatedly proven to not deliver on time or on budget!)
    • Forge.mil
      • US DoD effort to start an “open source” community around their requirements (initiated in 2009)
      • Sharing code, data standards, protocols, documents:
        • Enable cross-program sharing of software, system components, and services
        • Promote early and continuous collaboration among all stakeholder (e.g., developers, material providers, testers, operators, and users) throughout the development life-cycle
        • Rapidly deliver effective and efficient development and test capabilities for DoD technology development efforts
        • Help protect the operational environment from potentially harmful systems and services
        • 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
        • Eliminate duplicative testing and improve dependability by adopting common test and evaluation criteria supported by standard testing tools and methods
      • SoftwareForge now operational
        • Meant for US military use primarily
    • FOSS for defence
      • Software is underpinning everything – from weapons systems to vessels to operational aspects
      • Depending on external software technology providers only is a huge national security risk
        • Exposes one to external threats
      • FOSS allows one to not only consume, but also PRODUCE software assets
        • Which can become currency in global relationship management
      • On a grander national scale, help develop local IT expertise and industry
        • E.g.: US DoD has been catalyst for much innovation
        • Opportunity to leapfrog!
    • Recommendations
      • Each country DoD needs to set up their own SOA platform
        • Using FOSS products to give maximum flexibility
      • Each country needs to set up its own equivalent of Forge.mil
      • Set up shared registry of data standards
        • E.g.: Definitions of various types of vessels and their characteristics
        • (Not mandatory to use, but enable serendipitous reuse when possible)
      • Set up shared data centers using (FOSS) cloud computing technology for use within branches of the military as well as across
      • Make military software technology a strategic weapon for the country & allies
    • Summary
      • Service Oriented Architectures (SOA) is now the accepted approach for building very large scale systems that actually work
      • SOA enables scalable, strategic sharing of information in net centric operations
      • Free & Open Source Software (FOSS) provides a superb platform for building SOA solutions
      • FOSS provides intrinsic strategic advantages to the country
      • It can be done – local expertise is already there in every country
        • Look for it, enable it, sponsor it, nurture it
