  1. From Spaghetti to Lasagne 7 December 2009

  2. Ctac does eSOA What will you do in 5 years? eSOA is maintainable tailor-made SOA is the new Architecture and for everyone So not SAP specific Standard SAP is in the past from spaghetti to lasagne

  3. CTAC • Ctac is present in Belgium (2004) and the Netherlands (1992): its consulting force amounts up to 500+ consultants of which 120 in Belgium, mainly in SAP & Business IT • Ctac offers a full range SAP Services Portfolio • Implementation (various predefined template solutions available) • Application Maintenance & Hosting • Business Consulting, Improvement & Optimisation • Ctac is SAP Partner in multiple areas & SAP AiO (VAR) Partner in the Benelux • The Ctac holding is noted on the Amsterdam stock market (euronext).

  4. CTAC Enterprise Technology Management focusses on: • SAP NetWeaver, eSOA and integration with SAP-systems • Optimizes business processes with SAP NetWeaver as a basis • Raises productivity by using the SAP portal and composites • Integration of processes and applications using PI • Maintains qualitative Master Data with MDM

  5. Agenda • What is Enterprise SOA and why is that important? • What is Sap NetWeaver and where are we now? • Sap NetWeaver technology in some more details • The impact of eSOA on the IS organisation

  6. Objectives • Obtain an understanding of: • the rationale behind SAP’s SOA strategy; • the role and components of a technology platform; • NetWeaver as supporting technology platform for implementing SOA; • the challenges the technology brings and its impact on IS organisations

  7. Agenda • What is Enterprise SOA and why is that important? • What is Sap NetWeaver and where are we now? • Sap NetWeaver technology in some more details • The impact of SOA on the IS organisation

  8. Present : 2010 • Focus on business networks • Lots of “casual” users • Industrial-specific processes • Business performance, grow! Strategic drivers for change Past • Focus on Internal efficiency • Less users with special training • “One-size-fits-all” solution • Standardization, cost savings

  9. Business Driver • Strategic differentiation • InvestmentFocus • IS Enabler • Servicebased Platforms • Agile Development • Assemble /Build Differentiation • Business Driver • Internal Efficiency • Cost Focus • IS Enabler • Best Practice based packaged application(ERP, CRM, SCM,…) • Buy Strategic importance of your processes Core Support Process execution compared to your competitors Under perform Market perform Out perform Differentiation Matrix Identifying the Need for Change Differentiation Zone Parity Zone

  10. Application Development with SAPInternal reflection • SAP recognised that customers were asking more than only ERP and dull GUI screens that nobody seemed to like anymore. • SAP recognised that customers were looking for application platforms based upon open standards; applications that could easily interoperate with other applications within the company and with external systems. • SAP recognised that Java and .Net were strong development languages highly adopted by the development community. • SAP recognised that Service Oriented Architectures would be the next hype in techno land.

  11. SOA Service Oriented Architecture: a new hype?! SOA is the new Architecture for everyone It is not invented by SAP

  12. Some SOA misconception • SOA is a new technology • SOA is a marketing term • Webservices = SOA • Everything should be a webservice • The more webservices, the better • It is not possible to start with small projects • SOA is still immature

  13. The term “SOA” in wikipedia • Service Oriented Architecture (SOA) is an architectural style that guides all aspects of creating and using business processes, packaged as services, throughout their lifecycle, as well as defining and provisioning the IT infrastructure that allows different applications to exchange data and participate in business processes regardless of the operating systems or programming languages underlying those applications. SOA represents a model in which functionality is decomposed into small, distinct units (services), which can be distributed over a network and can be combined together and reused to create business applications. These services communicate with each other by passing data from one service to another, or by coordinating an activity between one or more services. • SOA is an architectural model, not a technology • Enterprise Service Bus (ESB) • Services are often executed as Web Services

  14. Lego and SOA

  15. What is a Service Definition : “A callable software component that is self-contained and self-describing and that is accessed via the exchange of messages. A service has a clearly defined interface.” • Web Services: • Act as a blackbox with obligatory input and a fixedresult • Can be published and called based on open technology standards (HTTP, XML) • Works in synchronous and asynchronous scenarios • A Web Service allows simple communication between different systems since it is using simple text messages in stead of complex and costly to maintain RPC. Stand alone No guarantee No Governance

  16. +SOA ES eSOA What is an Enterprise service? Definition : “An Enterprise Service is a service with the SAPBusiness logic!” eSOA is SAP specific Business logic Scalable defined repository https://www.sdn.sap.com/irj/sdn/esworkplace

  17. Components of a Web Service Yellow Pages UDDI Service Directory HTTP(S) HTTP(S) Service Discovery Service Publication WSDL WSDL Service Execution Web Service Consumer Web Service Provider SOAP HTTP(S) e.g. J2EE Web Application e.g. ‘Create Order’ e.g. R/3

  18. Summary • SOA is an architectural model, not a technology • Services are often executed as webservices • Platform independent • Services and enterprise services (sap: eSOA) • Enables possibilities (www.webservices.nl , www.xmethods.com ,…)

  19. Agenda • What is Enterprise SOA and why is that important? • What is Sap NetWeaver and where are we now? • Sap NetWeaver technology in some more details • The impact of eSOA on the IS organisation

  20. Application Platforms An Application Platform is an out-of-the-box integrated suite of common infrastructure services to build, integrate and run applications. Channels (Portal, Kiosk, Smartphone, etc) Process (Collaboration, Workflow, etc) Integration Lifecycle management & Security Solution modelling & development Application Service Application Service Application Service Application Service Common Data/Information

  21. Netweaver History • SAP NetWeaver™ technology platform is an integration, application and business process platform which helps with: • Reducing the total cost of ownership • Facilitating integration and orchestrate Information, People and processes across departments and technologies. • SAP NetWeaver is the technical basis for mySAP™ Business Suite and SAP® xApps™ and is a Webservices-based platform

  22. SAP has transformed its SAP proprietary Basis Platform into an Application Platform “NetWeaver” SAP’s core business used to beproviding best practice functionality for different business areas R/3 CRM SRM … BI SAP Basis / ABAP WB And revolutionised its business suites by making functionality available as enterprise services. A visual overview With NetWeaver 2004S, SAP has realised : A fully integrated and SOA based Application Platform supported by a rich repository of out-of-the-box application services.

  23. Putting all components togetherThe Strategic value of SAP NetWeaver as Business Process Platform

  26. Swaps Swaps Systems Systems Cash Flow Cash Flow G/L G/L IRS IRS System System IT challenges are considerable • Enable service of existing legacy-applications is difficult • Spaghetti of GUI, workflow, business logic and data • Parallel use of new services and old transactions • How define services (granularity)? • ESB is complex technology • Qualified competencies needed • ESB is very flexible: ‘create your future mess…’

  27. In practice Its not simple: • A lot of acronymes, standards and technologies • Every vendor has SOA solutions • How to justify IT-investments with the business? • Is there a shot-term business value? • Where to start? Technical issues (to expect!) • Security • Performance • maintenance • ….
