    • IBM Software Group An ESB enables “Loose Coupling” of Services Turn this… …into this. Service Service Service Service Service Service Service Service Interface Interface Interface Interface Interface Interface Enterprise Service Bus Interface Interface Interface Interface Interface Interface Interface Interface Service Service Service Service Service Service Service Service Decouples the Allows for Enables more Enables you to point-to-point dynamic flexible coupling find both the connections selection, and decoupling of applications and from the substitution, and the applications the interfaces for interfaces matching re-use RESULT Greater Business Responsiveness 12
    • IBM Software Group What is an Enterprise Service Bus (ESB)? Flexible connectivity infrastructure for integrating applications and services to power your SOA Built on MESSAGING ROUTING messages between services CONVERTING transport protocols between requestor and service TRANSFORMING message format between requestor and service HANDLING business events from disparate sources Shape = Protocol Color = Data type 13
    • IBM Software Group SOA Critical Success Factors 1 2 3 4 4 5 5 Connectivity Ability to connect all assets Universal transformation Scalability and performance Transactions 24 x 7 operations Complex event processing 14
    • IBM Software Group IBM Delivers a World Class ESB Portfolio ESB: Advanced ESB: WebSphere ESB WebSphere Message Broker [+WDSTX] provides Web Services connectivity and provides universal connectivity and data data transformation transformation ESB Advanced ESB SOAESB SOA Appliance Connectivity SOA Appliances: WebSphere DataPower XS40XI50 enhances security, simplifies and accelerates processing for the ESB 15
    • IBM Software Group Application Integration Customer Challenges Customer Benefits Applications are not integrated in a flexible and Reliably and seamlessly exchange data reliable method across the enterprise, between multiple applications reducing business responsiveness Manage differences between multiple Differences between many internal and applications and business partners partner applications must be managed Adopt an enterprise wide, flexible, service Maintaining point to point or custom written oriented approach to integration integration interfaces is cost and time prohibitive Application Connectivity Application and Partner Mediation Enterprise Integration Backbone Suppliers Customers Assure reliable and flexible information flow between diverse applications and organizations 16
