    • ESB’s-MuleESB Swati Bansal 05-April-2012© 2011 GrapeCity inc.
    • Agenda• Need for ESB• ESB Overview• When use ESB?• Open Source ESB-MuleESB• MuleESB in Lifeway.com © 2011 GrapeCity inc. 2
    • A Typical SOA Application© 2011 GrapeCity inc.
    • SOA without ESBImplies Point-to-pointapplication integration• Troubleshootingdeployments is painful.•Changing/adding newcomponents is tedious.•No consistentmechanism to react tofailures. © 2011 GrapeCity inc. 4
    • ESB’s-Enterprise Service BusUse ESB as the backbone of all communications of SOA deployment © 2011 GrapeCity inc.
    • What is ESB?• Software architecture model used for designing and implementing the interaction and communication between mutually interacting software applications in Service Oriented Architecture.• SOA with ESB = Hub and Spoke Architecture (acts as central "bridge" or "gateway" to all applications exposing services underneath it) © 2011 GrapeCity inc. 6
    • Key Terms:• Bus: Analogous to a computer hardware bus, allows applications to plug in and out with ease, without any need of a system restart. Allows for: – Message Routing – Message Monitoring – Logging traffic• ESB Commodity Services: – Protocol conversion – Mapping: between data formats – Translation and transformation: Change data content based on rules. – Event handling• Message Queueing: Message queue is required to cope with differing handling speed and temporary failure of services. © 2011 GrapeCity inc. 7
    • ESB Acts As:© 2011 GrapeCity inc. 8
    • ESB Acts As:•Single Point of Access: Look for services in a single location. Change indeployment simplified.•Transaction Manager: Coordinate distributed transactions which multipleservices participate in, hence taking the load off the client.•Security Manager: Security aspects like authentication and authorizationcan be centralized.•Service Proxy: Function as a proxy for appliations that do not expose astandardized service interface to the world.•Gateway to the World: For service running in the outside world. © 2011 GrapeCity inc.

    • Benefits of ESB:• Increased flexibility; easier to change as requirements change.• Scales from point-solutions to enterprise-wide deployment (distributed bus).• More configuration rather than integration coding.• No central rules-engine, no central broker.• Incremental patching with zero down-time; enterprise becomes "refactorable". © 2011 GrapeCity inc. 11
    • MuleESB © 2011 GrapeCity inc. 12
    • What is MuleESB?• Mule ESB is a lightweight Java-based enterprise service bus (ESB) and integration platform.• Adaptive integration : – Standards-based and vendor-neutral – Seamless integration with existing infrastructure – Plug-in architecture allows for building block approach – Use with any application server or standalone• Development simplicity: – Simplified programming model – Ease of use through configuration and control – Rapid development and deployment through code reuse• Open source advantage: – No expensive up-front license commitments – Access to source code allows customization and lowers risk – Vibrant developer community © 2011 GrapeCity inc. 13
    • Mule ESB Architecture• Architecture is based on concepts discussed in Enterprise Integration Patterns © 2011 GrapeCity inc. 14
    • Mule Components Endpoint– Channel, MessageReceiver, Connector Transformer– Message transformation / enhancement Router– Message flow control (inbound/outbound) Service Component– Your integration logic lives here © 2011 GrapeCity inc. 15
    • Mule Configuration Spring based mule-config.xml (default) Multiple config files using import © 2011 GrapeCity inc. 16
    • Mule Example• http://www.youtube.com/watch?v=PXj48XoMalg&fea ture=relmfu © 2011 GrapeCity inc. 17
    • Mule ESB in Lifeway © 2011 GrapeCity inc. 18
    • Why Choose Mule? No prescribed message format– XML, CSV, Binary, Streams, Record, Java Objects– Mix and match Zero code intrusion– Mule does not impose an API on service objects– Objects are fully portable Existing objects can be managed– POJOs, IoC Objects, EJB Session Beans, Remote Objects– REST & Web Services Easy to test– Mule can be run easily from a JUnit test case– Framework provides a Test compatibility kit– Scales down as well as up © 2011 GrapeCity inc. 19
