2 AGENDA Business oriented SOA: Agility and Flexibility Application Integration: Policy-driven ESB Process Integration: orchestration SOA Events: Management of SOA s SOA vision and outlook Page 1

3 Are you familiar with this situation? Initial situation MAIL 1999 High redundancies through isolated stovepipe solutions Missed business opportunities through lacking/inconsistent information, little exchange, unclear data ownership High cost of maintenance/ modification/extension through unmanaged spaghetti interfaces Source: Deutsche Post World Net Page 2

4 What is the IT challenge in today s fast moving world? Changes in the Process Architecture influence directly the IT Application landscape and vice versa Objects of discourse Process architecture Business processes Business rules Application architecture A B C D E Applications Databases Connectivity Infrastructure architecture LAN DBMS Middleware Networks, Storage Operating systems, hardware platform Source: Deutsche Post World Net Page 3

5 And what is the solution? Vision: A logical layer decouples business and technology Objects of discourse Process architecture Business processes Business rules Logical service architecture Application architecture A B C D E Business domains and services Business objects SOA Framework Applications Databases Connectivity Infrastructure architecture LAN Source: Deutsche Post World Net DBMS Middleware Networks Operating systems, hardware platform Page 4

6 What is the basic idea of SOA? Modular services can be assembled like Lego pieces into new applications Complaint Management Process Customer data maintenance Data entry and Data analysis segmentation ( ) Products CampaignComplaint development processing Access coordinationactivity / cost-benefit Responsecontrolling capture Evaluation / feedback Evaluation ( ) Relationship ( ) Production Billing Source: Deutsche Post World Net Page 5

8 Dimensions of Integration Scenario ƒ Network Objective Semantic Integration, encapsulation, service representation Focus Remote functionality invocation Interaction Document or Object oriented Office Automation Data Integration Application Integration Process Integration SOA Source: Deutsche Post World Net Page 7

9 Application Integration Evolution Next generation of an Enterprise Bus Web s Simple functionality invocation using internet standards Enterprise Bus Encapsulation of whole communication and mediation functionality within an SOA Framework Increased flexibility by policy driven mediation Page 8

10 Application Integration: Plain Web s Oriented Architecture Web s Enterprise Bus Next generation of an Enterprise Bus WSDL Get WSDL file from Web Provider (WSP) Consumer WSP stub XML http XML Web Provider Generate static bindings for WSP invocation (stub) Generate SOAP message and send it to Web Provider Receive response document from Web Provider Loosely coupled applications Usage of standards and proven technology for communications But poor non-functional capabilities, needed essentially for an Enterprise SOA Source: Deutsche Post World Net Page 9

11 ESB added value beyond basic mediation Web s Enterprise Bus Next generation of an Enterprise Bus Consumer SP stub Auth stub Priv stub Tran stub KM stub Provider To fulfill enterprise requirements, additional functionality is required Custom implementation by each participant is wasted effort Transformation Registry Key Management Authentication Privilege Page 10

12 ESB added value beyond basic mediation Web s Enterprise Bus Next generation of an Enterprise Bus Consumer Validation Compression Encryption SP stub Auth stub Priv stub Tran stub KM stub ESB encapsulates WS complexity Provider Decryption Decompression Authorization/Authentication Transformation Validation Compression Encryption To fulfill enterprise requirements, additional functionality is required Custom implementation by each participant is wasted effort ESB encapsulates WS complexity Transformation Registry Key Management Authentication Privilege Page 11

13 Which vendors are trying to provide ESB solutions? Web s Enterprise Bus Next generation of an Enterprise Bus Examples Open Source/ Freeware Apache SOPSOLUTIONS SOA Mediators SOPSOLUTIONS Big Players Oracle Microsoft IBM SAP New Vendors Systinet SOA Software Cape Clear Cordys ESB Market CORBA IONA Borland EAI Tibco WebMethods SeeBeyond FusionWare PolarLake J2EE BEA MOM Sonic Fiorano Source: Deutsche Post World Net Page 12

14 What are the principle differences between ESB solutions? The ESB infrastructure must be flexible and offer long-term stability Web s Enterprise Bus Next generation of an Enterprise Bus 1 EAI-driven versus SOA-driven ESB solution 2 Hub & Spoke versus Federal Architecture 3 Single Vendor Product versus Best-of-Breed Integrated Solution 4 Proprietary versus Standard Technology (Java Business Integration JSR 208) 5 Configurative versus Policy-driven Mediation Next generation of an ESB Source: Deutsche Post World Net Page 13

16 Dimensions of Integration Scenario Orchestration Engine Objective Encapsulation of complete process business logic Network Office Automation Focus Remote functionality invocation Interaction Application Document or Object oriented Integration Data Integration Process Integration SOA Source: Deutsche Post World Net Page 15

17 Process Integration Scenario: BPEL Middle-Tier Solution (Extended) Other Order Management Customer System Impl. C SOA Adpt. Recommendation Use BPEL engine only for service orchestration avoid yet another (classical) integration scenario! Process Definition SOA Adpt. Customer Data SOA Adpt. Adapt. Fr. BPEL Runtime Adapt. Fr. Other SOA SOA Integration Infrastructure SOA Adpt. Production System SOA Components Non-SOA Technology invocation with content Use Case Impl. Legacy Systems Page 16

18 Are there good examples for SOA Frameworks? Deutsche Post has implemented a powerful SOA Framework including the next generation of an ESB SOPware SOPware Support SOPware Application Integration SOPware ToolSuite SOPware Data Integration SOPware Process Integration SOPware Security Integration SOPware Management of SOP s (MSS) Network Office Automation Data Integration Infrastructure Components Transport Java Security High Availability Application Integration Hardware, Operating System Process Integration Registry SOA Framework Source: Deutsche Post World Net Page 17

20 Events in an SOA Messaging Events when a message is processed by a participant Consumer E S B XML XML E S B Provider Contain MessageID, MessageExchangeID, ParticipantID, time Events can be used to track the propagation of messages in an SOA Overhead to implement event generation in each application => Integrate event generation in ESB Source: Deutsche Post World Net Page 19

21 Events in an SOA Correlation Consumer E S B XML Header: Process#4711 XML <?xml version="1.0"> <order id= 1234 id="1234 > <name>foo Inc.</name> <orderno>42</orderno> <items> <item/> </items> </order> XML E S B Provider Events when a message is processed by a participant Contain MessageID, MessageExchangeID, ParticipantID, time Correlation events contain MessageExchangeID and BusinessID SOA messaging events do not contain any business-related information provide correlation data via correlation events Possible sources for correlation data: Message headers (set by sender application) Message content (e.g., identified by xpath) Source: Deutsche Post World Net Page 20

22 Events in an SOA Complexity SOA events from one business process Page 21

23 Events in an SOA Complexity SOA events from one business process plus SOA events from other business processes plus other infrastructure events Page 22

25 SOA Vision and Outlook Technology SOA, SAM, BAM activity monitoring Lifecycle and resource management of Participants usage metering QoS monitoring Business activity monitoring High-level business events during business process execution Fusion Given the right infrastructure, SAM and BAM can be seen in context Aggregation will provide insights for impact analysis, capacity planning, evaluations Source: Deutsche Post World Net Page 24
