2. TOPICS
 Integration, SOA, and ESB
 ESB Market
 Why Mule ESB?
 Mule ESB advantages
 Mule flows
 Mule Message
 Mule Environment

3. INTEGRATION
Problems in Point to Point Integration
 Change in Message Producer's Endpoint URL will
affect the message consumers which are
accessing it.
 If Message Producers and consumers are
Exposed by different Protocols, they cant interact.
 If Message type of two applications are differs.
 Doesn't scale Single Points Of Failure Happens
more at application to application level, may not
be aligned properly with business goals.
 Tightly Coupled connections between
components.

4. SOA
 Design & develop smaller software components as
services for reusability
1. Service provider:
• It creates a web service and provides its information
to the service registry
2. Service broker:
• known as the service registry
• to make the information regarding the web service
available to any potential requester
3. Service requester/consumer:
• Invokes a service,

5. What is ESB ?
 An enterprise service bus (ESB) is a software
architecture for middleware that provides
fundamental services for more complex
architectures.
 Enterprise Service Bus (ESB) which simplifies
that integration and flexible reuse of business
components using standard service-oriented
architecture (SOA) providing a responsive, low-
cost, high-impact framework for the technology.

6. ESB MARKET
ESB Market Commercial ESB Products:
 IBM Websphere ESB
 Software AG Web methods
 Tibco AM Service Bus
 Oracle ESB
 Progress Software FUSE ESB

7. ESB MARKET
ESB Market Open Source ESB Products
 Mule Soft Mule ESB
 Apache ServiceMix
 JBoss ESB
 Apache Camel
 WSO2 ESB
 Open ESB

8. Why Mule ESB?
 The world’s most used enterprise service bus.
With over 3,200 production deployments in
mission-critical environments and an active road
map for future development and support.
 Mule ESB takes the complexity out of integration,
enabling developers to easily build high-
performance, secure, multi-protocol interactions
between heterogeneous systems and services.
• It´s Open
• It´s Light and it´s Fast:
• It´s Developer friendly:
• It´s Cloud ready:

9. MULE ESB
 Mule ESB is a lightweight Java-based enterprise
service bus (ESB) and integration platform that
allows developers to connect applications
together quickly and easily, enabling them to
exchange data.

10. MULE ESB ADVANTAGES
 The key advantage are :
1. Service creation and hosting
 Expose transport end-points, EJBs, Spring beans, and
POJOs as modular and reusable services
 Host services as a lightweight service container
2. Service mediation
 Separate business logic from messaging
 Shield service components from message formats and
protocols
 Enable location-independent service calls

11. MULE ESB ADVANTAGES
3. Message routing
 Route messages based on content and complex rules
 Filter, aggregate and re-sequence in-bound messages
4. Data transformation
 Exchange data across applications with varying data
formats
 Transform data as needed, based on need
 Format messages across heterogeneous transport
protocols

12. MULE FLOWS
 A flow is the construct together several individual
elements to handle the request, processing, and
eventual routing of a message. You can connect
many flows together to build a complete
application which you can then deploy on
premise, on Mule or another application server, or
in the cloud.

13. MULE FLOW
 How Message is Passing among different
applications.
 Carrying data from Message Providers to
Message consumers.
 While Carrying data it may transform,Route or
Filtered.
 Single flow can integrate number of applications.
 Configure XML
 Sub-flows

14. MULE MESSAGE
The data that passes through an application via one or
more flows.
Properties
 Inbound :Header
 Outbound:Payload.
Variables
 Flow variables- Apply only to the flow in which they exist.
 Session variables- Apply across all flows within the same
application.
 Record variables -Apply to only to records processed as
part of a batch
 Access using MEL(Mule Expression Language).

15. MULE ENVIRONMENT
 To Editions In MuleSoft to Work With Mule Studio
IDE.
 Community Edition : 80 % of features available
for Free.
 Enterprise Edition : 20 % of features are
Licensed.
 Download Mule Studio IDE Mule Management
Console(MMC)
 The java and mule environment variables must
be setup correctly for mule to start.
 MULE_HOME - should be the location of the
mule install
 JAVA_HOME - should be the location of the JDK

16. MULE STUDIO
Mule Studio Mule ESB Runtime:
Runtime Mule Server (Standalone/Embedded)
Mule Studio:
Integrated Development Environment to develop Mule
Flows.
Eclipse with Mule ESB Plugin:
Integrated Development Environment to develop Mule
Flows.
