2. Agenda Next generation business highly distributed,dynamic applications based on 'services' Design / Architecture Patterns provide re-useand accelerated development Infrastructure virtualization and refactoring improves business agilitySun Proprietary Page 2 3. Next Generation Applications 4. A Shift in IT Today's reality IT reacts slowly to business requirements, hasunpredictable reliability, inefficient IT is a cost center IT organization owns IT strategy Tomorrow's vision IT detects/acts in real time to business, reliably, with costscorrelated to business priorities IT is a profit center, providing value based business services,that drive business, focussed on business strategy How can we save money and enable new business? We need a roadmap and specific technology injection points?Sun Proprietary Page 4 5.

Next Gen Business Models- exposing core apps as business 'services' Salesforce.com CRM services Enterprise network services from BT and AT&T. Amazon & eBay e-commerce services used in collaboration with core enterprise apps. CBDI JournalSun Proprietary Page 6 7. Applications evolving as Graphs of ServicesSun Proprietary Page 7 8. Shifting to the Network Enterprise- Dynamic Mapping of Applications & Infrastructure Applications are assembled (via co-ordination / orchestration) of distributed services Application was: webserver / database, now Application is: Amazon.com No one writes the whole application, components delivered, imported The computer is assembled from heterogeneous compute & storage & network resources This requires a real-time approach to architecture XML XML XML EJBJSP cache/Midlets SQL AppWebfilterJ2ME 6 LDAP X 10 DB Dir MSG SLASun Proprietary Page 8 9. Using 'Patterns' to Architect Services 10. Services Oriented Architecture (SOA)- a shift to 'business' programming Loosely coupled, Coarse-grained, Process coordinated, business aligned, Network-based shared services SOA as an architectural style may best berealized using Java web services But how do we Refactor and map business processes to coarse grained SOA processes? Architect re-usable services & systems?Sun Proprietary Page 10 11. Patterns provide architecture re-use at multiple levels A pattern describes : a problem which occurs over and overagain in our environment the core of the solution to that problem,in such a way that you can use thissolution a million times over, withoutever doing it the same way twiceBuild Patterns Structural Architecture Styles implementation Abstract common architectures & requirements Micro-architecture Describe sub- Design Patternsarchitectures Used to express detailed functional designSun Proprietary Page 11 12.
