A high-level overview of some SOA concepts and of SAP PI, presented as part of the BCO6181 course at Victoria University

1. Intro to SAP PI …and SOA in the SAP World

2. SOA

3. http://geekandpoke.typepad.com

4. Service-Oriented Architecture Business + Technology! Expose app functionality via services A is for Architecture Usually focus on reusability Governance

6. The Business Side of SOA Think Processes, not Departments This is hard! Business Process focus, technology later

7. IT comes into play here

8. Governance Design-Time ‘Model’ Service Definitions Outside-In Design: 1st: interface first 2nd: implementation Library of artefacts Change control etc. Run-Time Focus on Control Usage metering & billing Enforce policies Service Discovery – UDDI Performance monitoring etc. More info: http://www.infoq.com/presentations/SOA-Governance-Development-Deployment-Runtime

10. ESB Enterprise Service Bus “Your SOA Middleware” Facilitates implementation of an SOA at run-time and design-time PI is SAP’s ESB

11. Standards… WS-* Soup of standards of various quality WS-I Basic Profile is pretty much all that counts to be honest Too many, complex standards without wide support Take a look yourself: http://en.wikipedia.org/wiki/WS-*

12. ES Workplace http://esworkplace.sap.com SAP’s “yellow pages” of standard web services There are 2,600+ service operations Public website, no login required

15. SAP PI

16. PI = Process Integration SAP’s Middleware product Message-Oriented Middleware + ESB (Enterprise Service Bus) Design-time governance features Many adapters from SAP and third parties Orchestration of different services across systems Monitoring, metering, etc.

17. Some Use Cases Suppliers send Invoices to ERP via XML (B2B) CRM triggers Refunds to customers in ERP via web service (SOA) PI aggregates many production stats messages and sends 1 big IDoc to ERP (orchestration) ERP HR updates Access Control system by writing into its database (A2A)

18. Design-Time Run-Time NetWeaverWebAS Java & ABAP Runtime Workbench Monitoring, alerting, etc. Enterprise Services Repository Global Data Types, Schemas, processes, mappings, etc. Enterprise Services Registry (UDDI v3) Integration Builder Routing rules, connections Integration Server Execution Environment System Landscape Directory System information, connection information, etc. Components More on the next slide!

19. Integration Server in Detail Stand-alone Java-only install with PI 7.3

22. High-Level Runtime Features Sync & Async XML-centric integration Supports the popular WS-* standards Supports ‘hub & spoke’ and federated deployment Out-of-the-box integration with SAP systems Different transformation technologies (drag & drop, XSLT, Java, ABAP) 1-to-1 and 1-to-n processing, message splits, multi-stage mappings, etc. Loosely-coupled development object model to facilitate reuse Stateful orchestration (avoid if possible)

23. Future Roadmap Java-Only deployment Robustness & Scalability improvements Tight integration with NetWeaver BPM Better JMS integration

24. Use at Post Single PI 7.11 system 3 Java nodes, 60GB RAM, IBM “Big Iron” 39 Interfaces 150,000 messages on an average day Peak load 1.2 million/day in about 3 months

25. REST …but that’s a whole new session
