  2. Whatis SOA?

  3. SOA is More Than Middleware and ESB Middleware and ESB arethecommunicationlayer Theyarethestreetsandcodeoftraffic

  4. Governance Frontend Services Semantics Abstraction Middleware Persistence Virtualization Security & Safety Physical Layer SOA istheMarketplacefor Services

  5. SOA is the Service Marketplace SOA caters for an infrastructure and basic services to make the execution of services as convenient as possible

  6. SOA ComponentStack Governance • Investment, arbitration, SOA marketing Frontend • Design, Accessability, Desktop Integration Services • ERP components, APIs, UDDI Semantics • BI, Search, Semantic Web 3.0, repository Abstraction • Programming, VM, ManagedRuntime Middleware • Messaging, Workflow, ETL, Data Source Persistence • DB, MQ, Filesys, Replication Virtualization • Ressource sharing, Scaling, Recovery Security & Safety • Firewalls, compliance, Access security, encryption Physicallayer • Network, Hardware

  7. How Do I Get SOA? Waystocontroluncertainty: learnfrom Cities

  8. Imagine SOA Governancelike City Administration Cities wentthroughthe same phasesofdevelopmentthan IT

  9. In thebeginning …. • therewereisolatedhabitats • Every farmautonomous • Water, nutrition … all suppliedbythemselves • That was inefficient

  10. Thenhabitatsstartedsharingservices • Common fountain • Farmsspecialiing in meat OR crop • Expert serviceswerecreated • Schools, smiths, waggoners, carpenters, bakeries … • Onetown wall protectseverybody

  11. Community ismoreefficientthanthesumofindividuals

  15. Demand iscontrolledbysupply Wewantsupplybecontrolledbydemand

  16. Usecasesof(e)SOA • Collaboration: Postingnewsto web site • Write article online • Nobackup • Write article offline • Go to web site • Post article • Change formatting • In realitymuchmorecomplicated • Whatwriterswant • Write article in outlook • Press send and …. Voila!

  17. UseCasesof(e)SOA • Findingdocuments • Today mostprojectdocis WRITE-ONLY • Findingismoredifficultthanwriting • SOA provides uniform dataaccess • Every searchenginecanspideranydatasource • Youcanchoosesearchengine • Youcanuse multiple search-engines

  18. Enterprise 2.0 Learns WWW • Enterprises adoptthesuccesful WWW • WWW isbased on services • WWW is a grown SOA •  • Learning from AMAZON, Google, XING, Wikipedia, eBAY et.al.

  19. Enterprise 2.0 • „Webification“ ofenterprisecollaboration • Central Sharepoints fordata • Life Collaboration • Enterprise Search • Wiki Libraries insteadofdirectorytrees • Enterprise widediscussionforums • ERP   Desktop Integration • Application  Outlook

  20. Social Networks are on therise • Socialcommunitieslike XINK, LinkedIn • Stay in touchwithbusinessfriends • The bigMathematicalbrain: Matheon • Best mathgenies form a newgiantmathbrain • Developer networks • No OSS anymore SDN istheplacetogo

  21. SOA isthegroundworkfor Enterprise 2.0 Enterprise 2.0 isbased on collaboration Collaborationrequiresservicesarchitectures

  22. Enterprise AppsBecome Services • Enterprise Suites turn into Service Collections

  23. Thinking different The importantthing in SOA is not so muchtoobtainnewtechnologyastodiscovernewwaysofthinkingaboutthem.

  24. Imagine SOA Marketplaceas a City • Cities meancommunities • SOA isforcommunities • Enterprise 2.0 is a community

  25. IT in ERP todayis „vendor-oriented“ The capabilityofprocuctsdecideswhatto do withthesoftware Recombinationoffeaturesisnearlyimpossible

  26. Wewantthebestofeach Wewantto „mash-up“ thefunctionalitiesofspecializedsoftware

  27. Windows isAlready a Mashup King Weuse Microsoft Office OrmayuseOpenOfficeinstead UseUleadPhotoImage Use Browser fromFirefoxor Flock DestopSearchfrom Google  Best ofBreed Just Download, install  Run

  28. ERP may Look LikeThisSoon • Scenario • Run MM on SAP ERP • Use Amazon andvendorcatalogues • Run SD on Microsoft Dynamics AX • SRM on Web-based SAP SRM • CRM on Jira • Financials on Oracle • PP on own IBM i5 • PM on systemofexternalservicepartner

  29. WWW isalready a freemarketofservices • Windows softwarefrom download.com • Email from Yahoo, google etc. • Shopping directoryby eBay • Books andelectronicsby Amazon • Homepageprovider, bloggertools, socialnetworks…

  30. SAP Is Readyfor SOA • Netweaver • BAPI delivers SAP asservices • Unfortunately not yetcomplete • Workflow connectstomessaging • SRM, CRM, BI areservicehubs • Fullconnectivity via RFC and HTTP • BusinessByDesign (ByD) • An excellentservicesuite • Dynamics AX andByD will be ERP champions

  31. HowGetting SOA?

  32. ChallengesofInteractingSocieties Freelyinteractingagentscreate an uncontrollable form ofcomplexity

  33. 3-Body Problem

  34. How Do YouControlComplexity? • Howtocontrolthecrewof a ship? • Howtoyoucontrol an army? • Howtogovern a city? • Howtoyoucontrol China, Zimbabwe?

  35. WaterfallDoesn‘tMeetComplexity • Waterfallmethodimplylinearity • Waterfallignoresthatactionmayreverberatetoearlierconditions • Waterfallis not agile

  36. How doyoucontrolplanets‘ motion? • Planetsarecontrolledbygravitation. • Gravitation produces a focalpoint. • Gravitation meansattraction. gravitation

  37. Attractioncontrolscommunities • Enterprises arecommunities • Attractionmaybe • More money, lesscosts • More creativeness • More funandjoy • More productiveness • Betterquality

  38. ADevine Circle • SOA CreatesAttraction • Attractioncreatesservices • Services driveenhancements in architecture • Better SOA createsmoreattractions

  39. SOA Staysand Falls With Services • SOA needsElementary (=Public) Services • Otherwise SOA islike a citywithoutcraftsmen • City Services: • Government,&Administration, Police, Justice • Streets, water&electricty, garbageremoval • Private Services • Craft, commerce (commoditiesandassistence)

  40. Johann Wolfgang Goethe Every bright idea has been thought of before, you only need to try thinking of it again. Alles Gescheite ist schon gedacht worden, man muss nur versuchen, es noch einmal zu denken.

  41. SOA Is Not New • SOA hasbeentheresincetheearlydaysofcomputing • Operating Systems Are Early SOA Implementations • BIOS Are Service Frameworks • Theycaterforservices in repeatingtasks • Printer drivers • Screen outout • Mouse, Windows, Drawing, Network etc.
