  1. 1. SOA: An Approach to Information Sharing BJA Regional Information Sharing Conference Minneapolis, Minnesota March 28, 2007 Scott Came Director of Systems and Technology SEARCH
  2. 2. Agenda <ul><li>By the end, you should know: </li></ul><ul><ul><li>What is SOA? </li></ul></ul><ul><ul><li>What is a reference architecture, and how does it help with SOA adoption? </li></ul></ul><ul><ul><li>What value does SOA bring to information sharing? </li></ul></ul><ul><ul><li>What resources are available to help you consider or adopt SOA? </li></ul></ul><ul><ul><li>What are some SOA success stories? </li></ul></ul>
  3. 3. What is SOA?
  4. 4. Lets start with “architecture”
  5. 5. Architectural Style <ul><li>An architectural style is a set of characteristics that distinguish an architecture </li></ul><ul><li>The characteristics are intended to produce certain effects in things designed according to the style </li></ul>
  6. 6. Architectural Styles: Integration Shared User Interface Shared Database File Transfer SOA
  7. 7. SOA is an architectural style <ul><li>SOA is an architectural style, not for houses, but for sharing information and functionality between systems </li></ul><ul><li>Like any architectural style, SOA has a set of distinguishing characteristics </li></ul><ul><li>There are many ways to build a functional house…the right one depends on what you find important </li></ul>
  8. 8. Distinguishing Characteristics <ul><li>Interactions between consumers and providers (of functionality, data) take place across a minimalist interface </li></ul><ul><li>Interface based on open (versus proprietary) standards </li></ul><ul><li>Interface defined in business event terms, not system or technology terms </li></ul><ul><li>Consumer can discover interface dynamically </li></ul>
  9. 9. What is SOA…really? <ul><li>A set of policies, standards, and guidelines that constitute the architectural style </li></ul><ul><li>A reference architecture can provide a starting point for these by standardizing terminology and then standardizing how concepts are implemented </li></ul>
  10. 10. The Global JRA <ul><li>The Global Infrastructure/Standards Working Group is defining a Justice Reference Architecture </li></ul><ul><li>The JRA: </li></ul><ul><ul><li>Establishes common terminology for discussing SOA </li></ul></ul><ul><ul><li>Evolves SOA concepts into reference standards/guidelines that you can use in establishing a specific SOA in your environment (rather than starting from scratch) </li></ul></ul>
  11. 11. Key JRA Deliverables <ul><li>The JRA itself (common terminology) </li></ul><ul><li>Service Interaction Profiles: Think “messaging standards” </li></ul><ul><ul><li>Web Services </li></ul></ul><ul><ul><li>Others </li></ul></ul><ul><li>Service Modeling Guidelines </li></ul><ul><li>Service Design Principles </li></ul><ul><li>Methodology for identifying services </li></ul><ul><li>Guidance on necessary investments to support services and interactions </li></ul><ul><li>Management/Policy guidelines </li></ul>
  12. 12. What SOA is Not <ul><li>The same as web services </li></ul><ul><li>Service buses and message brokers </li></ul><ul><li>An infrastructure investment strategy </li></ul><ul><li>The brainchild of any particular vendor </li></ul><ul><li>Radically new </li></ul>
  13. 13. Why SOA? <ul><li>What is the value? </li></ul><ul><li>How do I sell it? </li></ul><ul><li>Why is an architecture with these qualities a good thing? </li></ul><ul><li>What value will I get by adopting SOA as my integration / information sharing approach? </li></ul>
  14. 14. Agility <ul><li>Accessing capabilities through services, if done with care, should result in more agile integrated systems </li></ul><ul><li>Agility: the ability to adapt to changing business requirements and environmental context </li></ul>
  15. 15. Agility Makes a Difference <ul><li>Agility is the hallmark of successful modern enterprises </li></ul><ul><li>Citizens expect rapid response to changing requirements </li></ul><ul><li>In the public safety arena: </li></ul><ul><ul><li>Clever opponents </li></ul></ul><ul><ul><li>New partners and requirements </li></ul></ul><ul><ul><li>Policy initiatives </li></ul></ul>
  16. 16. How is SOA agile? <ul><li>Minimizing dependencies: loose coupling </li></ul><ul><li>Interoperability </li></ul><ul><li>When context changes, there is minimal impact on existing systems </li></ul><ul><li>What kinds of context changes can happen? </li></ul>
  17. 17. Summary <ul><li>SOA is a style of designing integration solutions to achieve technical and policy agility </li></ul><ul><li>SOA is not technology that you buy…it’s a way of thinking about positioning your technology capabilities for agile sharing </li></ul>
  18. 18. BJA/Partner Resources <ul><li>Global JRA: http://it.ojp.gov/topic.jsp?topic_id=242 </li></ul><ul><li>Training: </li></ul><ul><ul><li>IJIS/SEARCH SOA Seminar available through GTTAC </li></ul></ul><ul><li>Technical Assistance available through BJA partners </li></ul>
