4 SAP's Platform Delivers a New Level of Governance to Ensure Enterprise Readiness Manage & Optimize Analyze & Discover Model & Build Enterprise Services Repository: The Basis for End-to-End Co-Innovation and Governance Test, Integrate & Deploy Compose & Orchestrate Enterprise Services Repository Integration Scenarios Process Components Processes Service Interfaces Global Data Types Interface Mapping Moving beyond service definitions Services, business objects, processes Moving beyond development Business process expert, architect, developer Moving beyond discovery UDDI based discovery, lifecycle management governance Governance SAP 2008 / Enterprise SOA for the SAP Business Suite InfoDays 2008 / Page 4,

5 Lifecycle of SOA-based Applications SAP s Approach Governance along all phases of the lifecycle Enterprise Architects Analyze business requirements Discover available enterprise services in ESR for reuse Gap analysis Analyze & Discover Providers Design and model services Implement new business logic Create new services reusing existing assets and publish to SR Manage & Optimize Model & Build Administrators Manage change Security Monitor service execution (e.g. performance, availability, process progress, events) Integrate & Deploy Administrators Compose & Orchestrate Package and deploy application Configure runtime (adapt to IT landscape) Consumers Compose views by reusing implemented services and BOs Compose and orchestrate services and views to form new business process Test and validate SAP 2008 / Enterprise SOA for the SAP Business Suite InfoDays 2008 / Page 5,

6 Enterprise Services Repository is... the central repository where service interfaces and enterprise services are modeled and their metadata is stored. ES Repository - The metadata repository of all service objects for enterprise SOA Services Registry Services Registry - UDDI V3 compliant registry that supports publishing, classifying and discovering services SAP 2008 / Enterprise SOA for the SAP Business Suite InfoDays 2008 / Page 6,

7 Key Usage Scenarios Process Visibility and Design Governance Focus: Process Component architecture models in ES Repository, Drill down to standards based service interface design Value: Enable SOA Governance Benefit: Transparency into Business Semantics, Contextualization of Service metadata, Easy access to Enterprise services & gap analysis. Service Provisioning Focus: Model Service Interface based on GDTs, Provide Service Metadata, Seamless Tool integration Value: Manage service metadata in one central repository Benefit: Enable reuse of design time artifacts, End to end modeling support, Governed definition of SOA assets. Process Integration Focus: Use services defined in ES Repository for consumption in A2A and B2B scenarios Value: Enable integration in heterogeneous landscape Benefit: Collaboration knowledge of non-sap systems, Support for defining Integration Scenarios Composition Focus: Composition tools query Repository- Registry to discover services Value: Composite Application Development Benefit: Contract first development process, Easy discovery, consumption & composition.
