ESB inter-connects requestor and provider ESB provides Service Virtualization Intelligent processing of service request / responses, events, messages Service Provider Service Requestor What is an Enterprise Service Bus? Core Principles of the ESB Architectural Pattern ESB
What is an Enterprise Service Bus? A flexible connectivity infrastructure for integrating applications and services. An ESB performs the following between requestor and service • MATCHES & ROUTEScommunications between services • CONVERTSbetween different transport protocols • TRANSFORMSbetween different data formats • IDENTIFIES & DISTRIBUTESbusiness events
What can an Enterprise Service Bus do? An ESB enables integration between loosely-coupled applications and services within and across: Services oriented architectures – where distributed applications are composed of granular re-usable services with well-defined, published and standards-compliant interfaces Message driven architectures - where applications send messages through the ESB to receiving apps Event driven architectures - where applications generate and consume messages anonymously
What can an Enterprise Service Bus do? An ESB enables simple application integration across different platforms programming models messaging standards

Why can an ESB help your connectivity needs? • Reduce the number, size and complexity of interfaces • Reduces cost and risk involved as business changes and new opportunities arise • Promotes reuse – Data and business logic more usable and applications easier to service-enable • Dynamic real-time, event-driven SOA – replacing unresponsive, batch-updating IT systems
Leverage the benefits: Reliable and secure data movement anywhere in the enterprise Application Programmers focused on logic simplified programming tasks Dedicated environment Common tooling, management and operational support Why can an ESB help your connectivity needs?
Loose coupling requires greater investment More design work More implementation work Benefits of an ESB: Loose coupling
Tighter coupling tends to cost more over time Synchronizing multiple organisations on change Adapting, redeploying updated components without affecting others Making changes is hard and expensive, or impossible Different parts of the solution are difficult to manage separately Hard to move, hard to scale, hard to distribute, hard to replace More coupling implies more expensive testing Benefits of an ESB: Loose coupling
Benefits of an ESB: Loose coupling Delivery Assurance Semantic Interface Location Language Data Format Interaction State Provider Consumer Business Data Model Service Version Security Protocol Service Provider Identity Platform Time
What is an Enterprise Service Bus? Business Innovation & Optimization Services Provide for better decision-making with real-time business information Interaction Services Process Services Information Services IT ServiceManagement DevelopmentServices Manages diverse data and content in a unified manner Enables collaboration between people, processes & information Orchestrate and automate business processes Enable inter-connectivity between services ESB Integrated environment for design and creation of solution assets Manage and secure services, applications & resources Partner Services Business App Services Access Services Apps & Info Assets Connect with trading partners Build on a robust, scaleable, and secure services environment Facilitate interactions with existing information and application assets Infrastructure Services Optimizes throughput, availability and performance SOA Reference Architecture – Model of the Logical Architecture
What is an Enterprise Service Bus? An ESB-centric view of the logical model ESB Application Services Security Interaction Process Information Management Services Development Services Partner Business App Access Management Registry • Outside of the ESB: • Business logic (“Application Services”) • Tightly coupled to the ESB: • Service Registry • Tooling required for ESB • Development • Administration • Configuration (via Service Registry) • Loosely coupled to the ESB: • Security and Management
What is an Enterprise Service Bus? “Uncluttered” Well Defined Self-Contained Application / Service Logic The ESB decouples connectivity logic from application and process logic – making SOA possible Flexible “Uncluttered” Business Process Logic Process Logic Intelligent Connectivity Logic Connectivity Logic The Enterprise Service Bus Application/Service Logic

Deciding... to use WebSphere ESB You use WebSphere Application Server Your team has skills with WAS Administration and Java coding You are now or planning on developing business process using WebSphere Process Server WebSphere ESB and WPS have common tooling, programming model, and runtime You are integrating with ISV business applications hosted on WAS or 3rd party solutions which extend and support WAS You are focused on standards based interactions using XML, SOAP, and WS* You want to mediate between Web services and existing systems using JMS and WebSphere JCA Adapters Reliability and extensive transactional support are key requirements You want to minimize your server investment by co-hosting WebSphere services and ESB in one application server You want integration with other IBM WebSphere and Tivoli products
Deciding... to use WebSphere Message Broker You are currently using WebSphere MQ or WebSphere Message Broker Migrate to V6; implement ESB Patterns Leverage existing WMB skills You have extensive heterogeneous infrastructures, including both standard and non-standards-based applications, protocols, and data formats You have extensive MQ skills and infrastructure You are using Industry formats such as SWIFT, EDI, HL7 You are integrating core z assets (e.g. connecting to CICS COBOL applications) You are implementing a wide range of messaging and integration patterns Examples include event processing, message splitting, aggregation You need extensive pre-built mediation support To achieve very high-performance with horizontal and vertical scaling You have complex transformation needs Reliability and extensive transactional support are key requirements You want integration with other IBM WebSphere and Tivoli products
Deciding... to use WebSphere DataPower XI50 Ease of use is a pre-dominant consideration Simple experience of drop-in installation and admin-based configuration with no or minimal development required You are transforming between XML-and-XML or XML-and-any other format Your interaction patterns are relatively simple Your mediation requirements are met by the existing DP mediations and minimal extensibility is needed You are using XML-based or WS-Security extensively You require use of advanced Web services standards You need to minimize message latency when adding an ESB layer You are doing extensive XML processing combined with high performance reqs Your ESB must be in production very quickly You want integration with other IBM WebSphere and Tivoli products
Deciding... to use WebSphere DataPower XS40 You are using an ESB gateway pattern All XML interaction with 3rd parties should go through XS40 for XML threat protection
