Example scenario

Features of Make A Trip

Jagadeesh.mri@gmail.com

Login into MakeATrip

Search flights and book tickets

Registration module

Jagadeesh.mri@gmail.com

In order to login, customer must register into the MakeATrip

Registration process is very tedious.

Login Module

Jagadeesh.mri@gmail.com

Customers expect flexible authentication like Login through Google and Facebook.

APIs to be used

Jagadeesh.mri@gmail.com

Facebook API and Google API need to be used in MakeATrip application in order to incorporate the Login through Social media option.

Search and Book tickets

Jagadeesh.mri@gmail.com

To Search and book tickets, customer must enter the origination, destination and date of travel.

On click of search button, MakeATrip app should internally contact various flight operators, gather all flights information and render the response to the customer.

So MakeATrip App must be integrated with various types of other applications like Indigo, GoAir and AirIndia in this case.

All Integrations

Jagadeesh.mri@gmail.com

• Make sure the client code never requires to be changed Loose coupling Logical coupling

Best way to integrate

Jagadeesh.mri@gmail.com

• Integrate two applications with a contract

• As long as the contract remains same, the client should not change its code though the code is changed on service side.

• i.e. The service is free to change its logic as well as the implementation.

• Service can be implemented by C or C++, it is free to migrate to Java or .NET as long as it follows the contract.

Loose coupling

Change in the contract

Jagadeesh.mri@gmail.com

• Though the contract is changed, the client side code is not required to be change.

• To achieve this, the client should not know any details about the service and vice versa.

• So the client and service should be completely isolated by using a middleware server i.e. MOM (Message Oriented Middleware).

Logical coupling

• Implement lot of JMS listeners

• Implement various connectors like Facebook connector, Google connector, SOAP, RESTful, Database connector.

• The overhead of JMS middleware.

• Implement lot of JMS listeners

• Implement various connectors like Facebook connector, Google connector, SOAP, RESTful, Database connector.

• Implement various payload transformers

• Implement various filters and routers

• Using JMS queues to interconnect multiple components is costly.

• The overhead of JMS middleware.

Issues to be faced by developers

Jagadeesh.mri@gmail.com

• Connectors More than 120 predefined connectors

Endpoint based connectors

Operation based connectors

How mule makes developers life easy

Jagadeesh.mri@gmail.com

• Filters Mule provides so many predefined filter to filter the requests based

on conditions.

Jagadeesh.mri@gmail.com

• Transformers Mule provides various transformers to transform the payload from

one representation to other

Jagadeesh.mri@gmail.com

• Routers To perform unicasting To perform multicasting

• In-memory queues To reduce the overhead cased by JMS interactions

Jagadeesh.mri@gmail.com

• Error handling

• Enterprise services like security

• A way to expose RESTful web services

• Batch processing

• Cloud deployments

• On-premises deployments

Mule ESB

Jagadeesh.mri@gmail.com

Mule ESB contains set of message processors interconnected through in-memory queues

So it is called as BUS

But Mule provides enterprise services as well so called as ESB (Enterprise Service BUS)
