Open Source Enterprise Service Bus Why and which one should you choose?

by Attune World Wide / /

Data exchanges between the companies have increased significantly and the number of organizational applications which must be integrated has also increased significantly. As a solution, companies prefer to use ESB (Enterprise Service Bus) in almost every sort of integration project, no matter which data formats, transport protocols, technologies or environments such as .Net or Java are used. Though the decision to implement and use ESB is an easy one to make, the difficulty arises when one has to decide which ESB to use?

This blog is intended to help you by explaining why should you choose to use ESB and which one to choose.

Oracle Service Bus

It is a proprietary ESB from oracle. It is a component of the OFM (Oracle Fusion Middleware) Stack. There is hardly any functionality which Oracle has not provided in its ESB. The tools are quite stable and powerful while for most of the products graphical editors are there. Support is also provided by the database giant for the most conceivable SLAs (Service Level Agreements).

The OFM is based on the industry standards such as SCA, SOAP, BPEL, or Java EE. These products are proprietary and hail from multiple acquisitions that Oracle has made over time. This proprietary ESB suite can offer almost every conceivable function and covers almost all the SLAs. However, many of these SLAs or functionalities are not required in most of the projects.

Mule ESB

It is an open source ESB which possesses a broad array of features including intuitive Eclipse based tooling and simple installation. It is very lightweight and extensible ESB solution, and part from its open source version also comes in commercial enterprise version. Some imperative advantages offered by Mule ESB include availability of B2B product connectors such as for Salesforce or SAP, and efficient implementation of the integration scenarios through graphical editors.  However, it misses on the functionality of a suite. Another negative aspect of Mule ESB is the small community.

Fuse ESB

Like Mule ESB, Fuse ESB is also a pure ESB and is not a suite. Its basis lies in the actual standards in the integration environment like Apache Camel and Apache CFX. Fuse ESB was earlier a part of FuseSource, but after Redhat’s acquisition it has come under JBOSS division. In order to become a unified suite Fuse ESB has to wait for some more time and it will be integrated into JBOSS Enterprise SOA platform.


There is no silver bullet which can solve all your integration problems. Out of the above mentioned three Enterprise Service Bus Solutions proprietary solution from Oracle can be a good choice for those who can afford a perceived higher complexity and higher costs in lieu of strong support and high functionality. On the other hand, open source solution like MuleESB can be a wise choice as it offers a rich set of features, flexibility, and ease of use and relatively lower costs.
