3 SOA Governance is a key requirement for overall successful SOA implementations Gartner You only need one service to need governance. You only need one service to destroy your business. 3

4 A scenario on the importance of SOA governance* Client focusing on service reuse Accounting department Sales xx Order fulfillment 1. Provide a currency service that fills a specific line of business (LOB) xx 2. Other LOBs start using the service App. 1 xx xx App. 2 Currency conversion service 3. LOBs increase use of services / quality suffers 4. Service is fixed at provider s expense Legal xx xx 5. Fix works temporarily but problem reappears Purchasin g 6. Maintenance costs soar / provider ends service * Scenario from Introduction to SOA Governance, Bobby Woolf. 4

5 SOA Governance drives symbiotic relationships SOA Governance: Defines who can make decisions and what decisions can be made SOA Management Execution of the underlying infrastructure that supports Service Lifecycle Management SOA Runtimes and Enforcement SOA Governance SOA Runtimes And Enforcement SOA Management Enforcement of Runtime policies and Mediation of Service Consumers and Providers Each component is required to complete the overall SOA framework Each component will have a piece of overall SOA Policy 5

8 WebSphere Service Registry & Repository: Proven Value WSRR deployment on average results in: 30% increase in software reuse 25% reduction in integration costs 40-60% improvement in application maintenance productivity. On average, the ROI (in WSRR) ranges from 300% to 700% with a payback period of just 9 to 13 months. Source: Cross-industry averages b ased on estimates b y IBM s Business Value Assessment Team.

9 WSRR is the market leading registry/repository solution Analyst evaluations deliver the proof Gartner Report: IBM's Federated Metadata Management Strategy (April 2007) we strongly advise organizations that are strategically using IBM WebSphere for their SOA solutions to instead consider using WSRR Gartner s Yefim Natis: By 2010, more than 40% of SOA projects will use a centrally managed extended service registry, up from less than 5% in 2006 (0.7 probability) 9

10 Overview of WSRR

11 WebSphere Service Registry and Repository Provides value throughout the service lifecycle IBM WebSphere Service Registry and Repository Enhance Connectivity Promote Reuse Optimize Service Usage Enable Governance 11

12 Promote Reuse Publish and Find Capabilities Build a catalog of trusted, high quality services Multiple methods to publish service Standards based API support to access to content including REST interfaces (Web 2.0) Service Discovery to discover deployed services on.net, Oracle/BEA, JBOSS and WAS servers Powerful queries to find best-fit services Faceted Search for a natural, user-friendly way to refine search using attributes, document types or classification Customizable ontologies to classify services aligned with your business domain 12

13 Enhance Connectivity Enrich capability Increase runtime flexibility of applications in your SOA Pre-built integration points allow applications to query WSRR for service end-points during runtime WSRR also provides associated metadata for those services Applications can invoke services that best match their needs WSRR ensures the currency of service end-points and associated meta-data 13

14 Enhance Connectivity of Enterprise Service Bus (ESB) Enable your ESB to be more dynamic, more flexible, more adaptable! IBM WebSphere Service Registry and Repository (3) Retrieves candidate providers information Message Message ESB Mediation Message Service (1) A Message is received (2) Invokes a selection mediation. (4) Executes matching algorithm to identify the provider service. (5) Message is routed to the selected endpoint. 14

15 Optimize Service Usage Manage capability Ensure utilization, health and performance of services Impact analysis using intuitive graphical views of service relationships Change notifications sent using / JMS Management of multiple service versions Clients can dynamically select latest version Support for publishing policies (W S-Policy & W AS Policy sets) and applying to services W SRR provides rich service information to better manage your IT infrastructure Understand dependencies between applications, processes and services W SRR can associate health and performance information as service metadata 15

16 Optimize Service Usage SOA Healthcheck Monitor the health of services in your SOA ITCAM for SOA monitors the health and performance of services Performance and Health Alerts WSRR captures alerts generated by ITCAM for SOA if a service is not performing as expected DataPower SOA Appliance or other ESB can react to the information in WSRR Monitor Services Resolve Services. Enforce Policy and Security WebSphere DataPower SOA Appliance 16

17 Enable governance Govern capability (1 of 3) Better control your SOA through governance Role based access to services for sharing and reuse Easy to use access-control editor Complete service life cycle management User definable collections of service metadata that can be governed together Controlled lifecycle state transitions Customizable validators Subscriber notifications Support for service promotion from one environment to another (e.g. staging to production) 17

18 Enable governance Govern capability (2 of 3) Better control your SOA through governance Governance profile that includes templates, lifecycles, generic validator, classifications and roles to help you get started quickly Prescriptive service lifecycle governance Service Provider / Consumer Contract Management Service Version Management Support for MQ Service definitions allowing governance and lifecycle management service-enabled MQ applications 18

19 Enable governance Govern capability (3 of 3) Better control your SOA through governance Centralized policies that can be shared and enforced across the SOA infrastructure New support for W ESB mediations and W AS policy sets WESB Mediations WAS Policy Sets WebSphere Service Registry and Repository Policy Policy WebSphere Message Broker WebSphere DataPower SOA Appliances 19

20 Take Control of your MQ Applications! Provide visibility to MQ applications by cataloging them as services Promote reuse of MQ services Make controlled changes to MQ services Based on usage by processes & applications Apply recommended practices to govern MQ services Just like for other services in your SOA Service visibility and lifecycle governance 20

23 WSRR integration with CICS Transaction Server 4.1 Support added into the CICS Web Services Assistants in CICS TS 4.1 Allows language structure generation to use a WSDL document that has been stored in WSRR as input instead of requiring it to be on the local file system. Supports the automatic publishing of WSDL documents (with metadata) generated from language structures Both DFHLS2WS and DFHWS2LS include parameters to interoperate with WSRR DFHLS2WS also includes an optional parameter so that you can add your own customized metadata to the WSDL document in WSRR 23
