Agenda § Introduction § What is WSRR? § WSRR Overview § Integration WSRR and Data. Power 2 © 2009 IBM Corporation

What is Web. Sphere Service Registry & Repository? 3 © 2009 IBM Corporation

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 J 2 EE Application that runs on Web. Sphere 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 4 © 2009 IBM Corporation

WSRR and Web. Sphere Data. Power 6 © 2009 IBM Corporation

Web. Sphere Data. Power XI 50 Purpose-Built ESB Appliance for SOA Integration § 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 7 © 2009 IBM Corporation

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 8 © 2009 IBM Corporation

Data. Power XI 50 Support for WSRR § Service Discovery – Data. Power 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 9 © 2009 IBM Corporation

Service Discovery Example § Web. Sphere Data. Power XI 50 – 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 Data. Power case, used to logically group service definitions for which Data. Power will provide mediation and policy enforcement 10 © 2009 IBM Corporation

Comments or Questions? 17 © 2009 IBM Corporation

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 Base. Object Interface. This is the parent interface that all other WSRR interfaces extend. § The Base. Object interface defines the basic set of attributes that can be found on all WSRR objects: – bsr. URI (ID) – Namespace – Version – Description – Owner – Creation. Timestamp – Last. Modified. By § It also defines the methods that allow you to associate metadata with objects in WSRR: – Properties – Relationships – Classifications 18 © 2009 IBM Corporation

Document objects § Files stored in WSRR (WSDLs, XML schemas, word docs, etc. ) are all sub-types of the Document type: – WSDLDocument – XSDDocument – XMLDocument – Policy. Document – Generic. Document, 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 Logical. Objects directly. 19 © 2009 IBM Corporation

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 Generic.
