1 Taming the SOA Chaos Debu Panda Oracle

2 Many initiatives lack Business/IT collaboration Business - Strategic modeling Requirements, powerpoint, visio model, Export files IT Executable modeling Enter order Sell products Service customers Get paid Update ERP Update GL No visibility into IT? Disconnect between conceptual model and implemented process Not sure how to improve process and reduce costs? Change in business rules and processes Fulfill order Print invoice Requirements not clear? Business is constantly asking for changes No visibility to process execution Change in partners and technology Slide 2

3 SOA Quiz Context: SMS to Which of the following is true: A. SOA is no longer a buzz word B. SOA creates chaos C. SOA is the answer to solve all IT chaos D. All of the above A Lucky winner will be appointed as Head of SOA COE Slide 3

4 Service Oriented Architecture Defined Service Oriented Architecture is an architectural style whose goal is to achieve loose coupling among interacting software agents. A service is a unit of work done by a service provider to achieve desired end results for a service consumer. Dr. Hao He, W3C Web Services Architecture Working Group Slide 4

5 Characteristics of Service Oriented Architecture Services have platform independent, self describing interfaces (XML) Messages are formally defined Services can be discovered Services have quality of service characteristics defined in policies Services can be provided on any platform Interoperable Composable SOA Loosely Coupled Re-Usable Slide 5

11 Key Standards: BPEL and Process Orchestration Standard markup language for composing a set of discrete services into an end-to-end process flow 10+ years of R&D from MSFT and IBM Rich Flow Semantics SalesDB start Duplicate Number! Optimized Bindings (not just Web services) Billing Transformation WS-Security A Process is a Service Router end Slide 11

12 The BPEL Process Manager Enterprise-strength infrastructure for BPM BPA Suite JDeveloper Process Modeler BPEL BPEL Designer Comprehensive and native BPEL implementation Easy-to-use modeling tool Workflow Services BPEL Process Manager Scalable and reliable engine Integrated BPM Services Workflow Decision Service Sensors WSDL Binding Web services Java, JMS File, FTP Dehydration Store (Oracle Database) Flexible binding framework Rich management and monitoring Core BPEL Engine Database Apps Process Console J2EE Application Server (Oracle AS, WebLogic, JBoss, WebSphere) MANAGE Slide 12

13 Business Process Blueprint Problem Models are only used for documentation and project planning. They become obsolete as soon as they are released. Gap between functional experts and technical experts. Solution - Business Process Blueprint - Shared metadata between BPA suite and SOA suite - Annotation on existing process metadata (NOT import/export) - Link operational models to strategic and conceptual models - Self-Documenting Processes - Self-Auditing Processes Business Analyst Process Outline Automated Activities Human Activities Business Events Business Rules Notifications Key Performance Indicators Application Composer Slide 13

15 Business Rules Rules de-couple decision services from SOA applications Are declarative not procedural Best practice for SOA applications Agility Transparency Can be generated from GUIs Applications requiring agility Frequently changing (legal) regulations Frequent policy changes to reflect market changes Requirements for high levels of customization Slide 15

Web services Management: Service virtualization in DMZ? end Select Lowest Offer 4. WS-Policy: System-wide service auditing Slide 22

23 Web Service Management Decouple your Security and Management Policies from Service Logic Without WSM, policy is hard-coded into each Web Service Result is siloed, inconsistent security and management A change in enterprise standards = rework of every service Higher cost, more fragile, harder to change No unified insight into operations across services Slide 23

24 Policy Attachment Search for available policies Attach/detach policies to a port Slide 24

25 Policy Management - Policies Search for policies Port dependency per policy Customize out-of-box policies create like Create new policies Edit policies Generate client policies Export/import policies Policy subject validation Slide 25

26 Oracle WSM Components BUILD Policies ENFORCE Policies Deployment as Gateway Process or as Embedded Agents MONITOR Policies Policy Gateway Policy Manager Policy Agents Oracle Enterprise Manager Web Services Slide 26

27 The UDDI - Registry? Provides visibility into services, service providers and related resources across the enterprise Policy Manager Policies SOA Infrastructure Services, BPEL Processes, ESBs SOA Repository XSDs, XSLTs, Etc. Slide 27

28 Who Uses a UDDI Registry? B2B partner relationships Provisioning/release of services to partners Portal integration to enable discovery Business analysts/it management Definition of service portfolio Visibility into current portfolio Impact analysis Product development Re-use of existing services Design-time access to related artifacts such as policies and schemas Slide 28

29 Key Benefits Enables service providers to categorize, catalogue and advertise offerings Allows users and consumers to find, access and/or invoke services that meet defined criteria Slide 29

30 Service Registry - Provides Key SOA Governance Capabilities Those IT managers seeking closer alignment with business goals must combine the ideas of registries, policy and business services to increase the chances of success. Gartner Group Lifecycle management via custom taxonomies Change notification Controlled view and access into services SOA metadata management Quality control through approval process Slide 30
