    5. 5. The Challenge…
    6. 6. … but even after yesterday’s promises…
    7. 7. … we still have the same IT mess, only worse Copyright © 2007, ZapThink, LLC
    8. 8. <ul><li>Companies require Business Agility… </li></ul><ul><li>Responding quickly to change , </li></ul><ul><ul><ul><ul><li>and </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Leveraging change for competitive advantage </li></ul></ul></ul></ul>Why does a business need an SOA Strategy? J Agility is the key to innovation
    9. 9. Service Orientation: A Business Approach <ul><li>It’s not about connecting things, it’s about enabling business processes & continual change </li></ul><ul><li>The core business motivation is business agility </li></ul><ul><li>Rather than “rip and replace” old systems – make them work better together </li></ul><ul><li>It’s not about technology, integration, or middleware </li></ul>
    10. 10. So What Does a SaaS SOA Strategy Entail? David S. Linthicum SOA Thought Leader and Practitioner [email_address]
    11. 11. Core tenants of an SOA Strategy… <ul><li>SOA is architecture – a set of best practices for the organization and use of IT, and the discipline to follow them </li></ul><ul><li>Abstracts software functionality as loosely-coupled, business-oriented Services </li></ul><ul><li>Services can be composed into applications which implement business processes in a flexible way, without programming </li></ul>Just as a building architect is more concerned with the space, not the walls, the IT architect is concerned with how people use the technology, not the technology itself
    12. 12. … which enable… <ul><li>Leveraging of legacy systems – SOA does not mandate replacement of runtime infrastructure, but enable migration when needed </li></ul><ul><li>Metadata to control how the system behaves instead of code – business logic trumps application logic </li></ul><ul><li>The contracted interface to matter most, not the underlying runtime environment </li></ul>
    13. 13. SOA shifts the way we think Traditional Distributed Approach Service Oriented Approach Designed to last Designed to change Tightly Coupled Loosely Coupled, Agile and Adaptive Integrate Silos Compose Services Code Oriented Metadata Oriented Long development cycle Interactive and iterative development Middleware makes it work Architecture makes it work Favor Homogeneous Technology Leverage Heterogeneous Technology
    14. 14. Emerging Web-Delivered Platform…a catalyst for change <ul><li>We are moving in three clear directions: </li></ul><ul><ul><li>First, the movement from visual to service-based interfaces </li></ul></ul><ul><ul><li>Second, the movement to outsourced or virtualized business processes </li></ul></ul><ul><ul><li>Finally, the acceptance of an on-demand platform for applications, services, and now development and enterprise architecture </li></ul></ul>
    15. 15. Advantages of a Web-Delivered Platform as part of an SOA Strategy <ul><li>While clearly a huge leap in thinking for many traditional developers and architects, the use of an on-demand platforms makes logical sense when considering the advantages of this model, including: </li></ul><ul><ul><li>The cost of the platform is always going to be less expensive than more traditional platforms, and also provide more value. </li></ul></ul><ul><ul><li>The shareable nature of this platform allows designers, developers, and architects to leverage best practices, reusing existing design, code, configurations, metadata, and application architectures. </li></ul></ul><ul><ul><li>Services deployed on this platform are immediately sharable, intra- or inter-enterprise, for any business purpose, including B2B partner integration. </li></ul></ul><ul><ul><li>Services may be layered into an orchestration mechanism or process layer for configuration into solutions. </li></ul></ul>
    16. 16. Externally Managed Systems Internal Systems External Trading Partners Internal Systems Normalizing Authentication Identity and Single Sign-On Protocol Translation Session Management Data Format Mapping Translation Error Handling Integration Monitoring Systems Management Business Process Workflow Business Activity Monitoring Service Providers Service Providers Approaching Integration Using SaaS-Delivered SOA
    17. 17. Integrating Applications, Services and Content Inside the Enterprise Outside the Enterprise Enterprise Systems On Demand Applications & Business Services On Demand Content Desktop Applications
    18. 18. Traditional Integration Approach <ul><ul><li>Costly to build, deploy and maintain </li></ul></ul><ul><ul><li>Complex, hard to change, doesn’t scale </li></ul></ul><ul><ul><li>Lengthy implementation </li></ul></ul>Different protocols Different standards Different data formats Firewall issues Multiple point-to-point connections Multiple business rules Different security models Different applications
    19. 19. SaaS Delivered SOA Solves the Need for Shared Infrastructure <ul><li>Simplifies the many to many problem </li></ul><ul><li>Moves complexity to the network </li></ul><ul><li>Increase value by providing shared infrastructure & services </li></ul><ul><li>Mediates technical and business differences </li></ul>
    20. 20. The Basic Architecture Web Delivered SOA System System
    21. 21. Getting Ready <ul><li>First, accept the notion that it's okay to leverage services that are hosted on the Internet as part of your SOA. Normal security management needs to apply, of course. </li></ul><ul><li>Second, create a strategy for the consumption and management of outside-in services, and use of a Web-delivered SOA, including how you'll deal with semantic management, security, transactions, etc. </li></ul><ul><li>Finally, create a proof of concept now. This does a few things including getting you through the initial learning process and providing proof points as to the feasibility of leveraging outside-in services. </li></ul>
    22. 22. B2B Exchange Distributor Service Provider Partner Service Provider Web Services Web Delivered SOA <ul><li>Abstract back-end functions, screens, and data stores and expose them as services </li></ul><ul><li>Mediate semantics through a transformation and routing layer </li></ul><ul><li>Mediate security, accounting for the difference within the source and target systems </li></ul><ul><li>Structure information for movement to and from the service provider </li></ul>Existing Systems ? What Needs to be Done
    23. 23. Remember, there are a few technical issues that you must address… <ul><li>Semantic and metadata management , or, the management of the different information representations amount the external services and internal systems. </li></ul><ul><li>Transformation and routing , or, accounting for those data differences during run time. </li></ul><ul><li>Governance across all systems , meaning, not giving up the notion of security and control when extending your SOA to the global SOA. </li></ul><ul><li>Discovery and service management , meaning, how to find and leverage services inside or outside of your enterprise, and how to keep track of those services through their maturation. </li></ul><ul><li>Information consumption, processing, and delivery , or, how to effectively move information to and from all interested systems. </li></ul><ul><li>Connectivity and adapter management , or, how to externalize and internalize information and services from very old and proprietary systems. </li></ul><ul><li>Process orchestration and service, and process abstraction , or, the ability to abstract the services and information flows into bound processes, thus creating a solution </li></ul>
    24. 24. Approaching SOA Using an On-Demand Platform <ul><li>Step 1: Accessing Current Enterprise Architecture Issues </li></ul><ul><li>Step 2: Making the Business Case </li></ul><ul><li>Step 3: Understanding Semantics </li></ul><ul><li>Step 4: Understanding Services </li></ul><ul><li>Step 5: Understanding Processes </li></ul><ul><li>Step 6: Understanding the Technology </li></ul><ul><li>Step 7: Execution and Assessment </li></ul>
