    • The following is intended to outline our general product direction. It is intended for information purposes only, and may not be incorporated into any contract. It is not a commitment to deliver any material, code, or functionality, and should not be relied upon in making purchasing decisions. The development, release, and timing of any features or functionality described for Oracle’s products remains at the sole discretion of Oracle. Next Level Challenges of SOA Moving Forward While Reducing Complexity Benefits New Challenges • Re-Focus on Innovation, New Business Services Large XML Payloads • Service Enablement of IT Assets Tearing Down / • Leverage investment, reuse De-coupling • Business Agility Silos • Better align with the Business Needs Unexpected Usage • Automate Business Function Demands • Business Process Orchestration • Composite Applications Meeting SLA • Flexibility Expectations • Loose Coupling, Modularity Increased Cost of • Easily integrated, upgraded, replaced Transacting • IT Cost Reduction Sharing Information • Shared Services Across Multiple • Eliminate Redundancy Services 4 2

    • Service Grid (a.k.a. SOA on App Grid) 8 Service Grid Combines Orchestration, Mediation, State Caching, Demand based provisioning, Deterministic GC WS-Addr WS-Addr Service <ReplyTo> <ReplyTo> Consumer Callback Callback My CRM / Portal ERP Services 1 2 3 4 5 BPEL CEP BAM Rules Service Provider State-aware continuous availability for service infrastructure, services, application data, and processing logic 1 2 3 4 =Service state data 5 =Stateful Service Orchestration 9 4
    • SOA on App Grid Value Proposition • Reduce cost of hitting back-end systems multiple times over the life of a session • Improve response times for service requests and front-end users while keeping load off backend systems • Improved fault tolerance without sacrificing performance • Ensuring predictable latency under increased sustained loads • Achieving dramatic overall increase in performance and throughput • Predictable scalability for XTP • Based on advanced software clustering techniques • Scales out linearly, whether 2 or 2,000 servers • Heterogeneous Environment • High-end / low-cost commodity hardware 10 Key Capabilities • Caching Results of Services Calls • To offload loads on backend services and SOA Infrastructure use side cache to cache results of service calls, c.f. Web cache • Without sacrificing consistency and programmability • Seamless State Management for Stateful Services • Without the need to enforce “state passing” / scrap book design patterns across the organization • Reduced/Eliminate dependency on disk persistence and State Repositories • Without sacrificing HA • Ability to Efficiently Handle Process XML Payloads within SOAs • Without Loss in throughput and increases in latency s • Data Grid and Compute Grid • Linearly scalable shared memory and logic • Intelligent co-location and affinity between processing logic and Grid storage 11 5
