  1. Andrew White – Software Developer 18 March 2010 Integrating WSRR and DataPower

  2. Agenda • Introduction • What is WSRR? • WSRR Overview • Integration WSRR and DataPower

  3. What is WebSphere Service Registry & Repository?

  4. WSRR is… • A Registry – it is designed to represent and govern SOA services • A Repository – conceptually like a database – that stores artifacts that can be queried at both design time and runtime • A J2EE Application that runs on WebSphere Application Server • Requires a relational backing store. DB/2, Oracle and MS SQL Server are supported • Leverages all security and clustering/HA capabilities of the WAS platform

  5. Web UI Custom Views Content / Business Models WSRR Capabilities, Extensions and Customisations Eclipse/ VS plug-in Tooling IBM Products Customer Applications Third Party Products Plugin Extensions Representation Of the Service Development Lifecycle to be Governed Role based UI Perspectives Emerging Standards Web Service API REST J2EE API SOA GovernancePolicies WebSphere Service Registry and Repository Validation Extendable Content Model Modification Notification Registry RepositoryCreate, Retrieve,Update, Delete,Query GovernanceTransition,Validate,Notify Lifecycle AdminImport, Export,Configure Classifications Access Control Definition of the BusinessDomains and Service Focus Communication Decision Rights ORACLE UDDI DB2 WebSphere Application Server Operating Systems: Windows, AIX, Linux, HP, zOS Solaris

  6. WSRR and WebSphere DataPower

  7. Purpose-Built ESB Appliance for SOA Integration WebSphere DataPower XI50 • Purpose-built hardware ESB for simplified deployment and hardened security at the message level, network level, and device level • Code-free, drop-in integration across IBM SOA foundation including support for MQ and JMS • Secures services on the network with sophisticated web services access control, policy enforcement, message filtering, and field-level encryption • Dynamic Web Services Policy framework (WS-Policy and WS-Security Policy) for SOA Policy enforcement • WS-I Basic Profile and Basic Security Profile support • Optimized to bridge between leading standard protocols at wirespeed, including web services, messaging, files, and database access • Enables transformation between a wide range of data formats, including XML, legacy, and industry standards and custom formats • Captures and emits events to facilitate web services management and enable business visibility in Business Activity Monitoring solutions • Simplified customization and configuration for accelerated time-to-market

  8. Why an Appliance for SOA Governance? • Hardened, specialized hardware for helping to integrate, secure & accelerate SOA • Many functions integrated into a single device: • Impact: connectivity will require service level management, routing, policy, transformation • Higher levels of security assurance certifications require hardware: • Example: government FIPS Level 3 HSM, Common Criteria • Higher performance with hardware acceleration: • Impact: ability to perform more security checks without slow downs • Addresses the divergent needs of different groups: • Example: enterprise architects, network operations, security operations, identity management, web services developers • Simplified deployment and ongoing management: • Impact: reduces need for in-house SOA skills & accelerates time to SOA benefits

  9. DataPower XI50 Support for WSRR • Service Discovery • DataPower WS-Proxy subscribes to service definitions stored in WSRR • Dynamically enforces policies and mediations for these services • Dynamic Endpoint Selection and Routing • Query WSRR for endpoint location(s) and dynamically route service requests • Service Metadata Lookup • Lookup service metadata such as XSLT, XML and XSD for use in service mediation

  10. Service Discovery Example • WebSphere DataPower XI50 • WS-Proxy – configuration object for proxying and/or mediating web services • WSRR Server – configuration object for WSRR server information • WSRR Subscription Object – configuration object for subscribing to WSRR • Status Providers – view the current state of the WSRR configuration objects • WSRR • WSDL Documents • Concept – in the DataPower case, used to logically group service definitions for which DataPower will provide mediation and policy enforcement

  11. Configuring DataPower and WSRR for Service DiscoveryWSRR Configuration • Configure WSRR Concept to group services • Upload Service Definitions (WSDLs) to WSRR

  12. Configuring DataPower and WSRR for Service DiscoveryDataPower Configuration • Configure DataPower WSRR Subscription Object • Configure DataPower WSRR Server Object • DataPower queries WSRR via the SOAP API • Support for WAS security and SSL • Subscribe to WSRR Concept or WSDL objects • Support for polling and manual updates • Configurable update interval

  13. Configuring DataPower and WSRR for Service DiscoveryDataPower Configuration (cont’d) • Configure DataPower WS-Proxy service to use WSRR Subscription

  14. Configuring DataPower and WSRR for Service DiscoveryDataPower Configuration (cont’d) • Configure Centralized Service Level Management for Subscribed Services • Configure SLM for all services in the WSRR Subscription • Optionally configure SLM for each individual WSDL component

  15. Configuring DataPower and WSRR for Service DiscoveryDataPower Configuration (cont’d) • Centrally Configure and Enforce Policies and Mediations for Subscribed Services • Mediation applied to all services in the subscription • In this case, WS-Security, SLM, SQL Injection filter and transformation • Configure and enforce WS-I compliance policy for the subscription

  16. Dynamic Endpoint Routing Example • Configure dynamic routing using the DataPower “route” action • Select WSRR endpoint lookup routing control file (stylesheet) • Configure parameters

  17. Comments or Questions?

  18. At its core, WSRR manipulates objects • Every entity in WSRR is represented as a Service Data Object (SDO). • All objects in WSRR also implement the BaseObject Interface. This is the parent interface that all other WSRR interfaces extend. • The BaseObject interface defines the basic set of attributes that can be found on all WSRR objects: • bsrURI (ID) • Name • Namespace • Version • Description • Owner • CreationTimestamp • LastModified • LastModifiedBy • It also defines the methods that allow you to associate metadata with objects in WSRR: • Properties • Relationships • Classifications

  19. Document objects • Files stored in WSRR (WSDLs, XML schemas, word docs, etc.) are all sub-types of the Document type: • WSDLDocument • XSDDocument • XMLDocument • PolicyDocument • GenericDocument, etc… • For certain document types, WSRR creates additional objects to represent the contents of the document. • These objects are known as Logical Objects because they are derived automatically from Document objects. • For example, a WSDLPort object is a logical object which is automatically derived from a WSDLDocument object. • It is not possible to create instances of LogicalObjects directly.

  20. Business objects • You can define your own types to represent objects that make sense to you in your SOA (e.g. an object type that represents an SLA). • These objects are known as Business Objects(referred to a concepts in the Web UI). • All Business Objects in WSRR are instances of GenericObject.
