Mule ESB

Mule ESB™ is the world's most widely used open source ESB (enterprise service bus)


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. Mule ESB enables easy integration of existing systems, regardless of the different technologies that the applications use, including JMS, Web Services, JDBC, HTTP, and more.


The key advantage of an ESB is that it allows different applications to communicate with each other by acting as a transit system for carrying data between applications within your enterprise or across the Internet. Mule ESB includes powerful capabilities that include:


  • Service creation and hosting — expose and host reusable services, using Mule ESB as a lightweight service container
  • Service mediation — shield services from message formats and protocols, separate business logic from messaging, and enable location-independent service calls
  • Message routing — route, filter, aggregate, and re-sequence messages based on content and rules
  • Data transformation — exchange data across varying formats and transport protocols

An ESB functions as a transit layer for carrying information, providing connectivity to a wide range of heterogeneous technology assets. The bus provides a set of capabilities to enable integration and service-oriented architecture (SOA), including service creation and mediation, routing, data transformation, and management of messages between endpoints.

With Mule ESB, there is no need to embark on a top-down transformative SOA initiative with a lengthy payback horizon. Instead, Mule ESB works with any existing infrastructure, and IT organizations can immediately see value from the service-orientation and decoupled integration that Mule ESB provides. At the same time, the Mule ESB Enterprise suite includes enterprise-class features and tools that enable Mule ESB to scale up and meet the most demanding performance or reliability challenges posed by even the largest SOA implementations.

Do I need an ESB?


 Mule and other ESBs offer real value in scenarios where there are at least a few integration points or at least 3 applications to integrate. They are also well suited to scenarios where loose coupling, scalability and robustness are required. This simple checklist can help aid a quick analysis on whether an ESB is right for you:

1. Are you integrating 3 or more applications/services?
2. Will you need to plug in more applications in the future?
3. Do you need to use more than one type of communication protocol?
4. Do you need message routing capabilities such as forking and aggregating message flows, or content-based routing?
5. Do you need to publish services for consumption by other applications?
