Enterprise Service Bus (ESB) is a standards-based integration platform that combines messaging, web services, data transformation, and intelligent routing to reliably connect and coordinate the interaction of significant numbers of diverse applications across extended enterprises with transactional integrity.

ESB software tools are extremely complex, striving to openly connect a wide diversity of Web services, back-end corporate processes and data-driven applications. All ESBs are heavily based on open Web and XML standards, and they use open methodologies to provide a connective layer to multiple endpoints. All ESB software tools support for core SOA (service-oriented architecture) standards.

Among ESBs on the market, there is no fundamental difference. Everything an ESB does functionality-wise is similar because it is created based on open standards. However, ESB vendors are trying to differentiate themselves on the margins through better developer-oriented tools or easier integration with common back-end enterprise systems, or aggressive support of early drafts of proposed Web service and integration standards. The following ESBs are power players:

Sonic ESB (Sonic Software)

Although everyone is talking about SOA, there are in fact few SOA projects going on, therefore not many techies actually got hands-on experience on SOA.

However it is time now to grab some knowledge on SOA in order to stay ahead of the crowd. Here’s just brief instruction of SOA. You can search tons of info on the web for this topic.

A service-oriented architecture (SOA) is an application framework that takes everyday business applications and breaks them down into individual business functions and process, called services. An SOA let you build, deploy, and integrate these services independent of applications and the computing platforms on which they run.

It is a big advantage for you to talk about your knowledge, or even better, – hands-on experience on ESB during an interview. If your goal is to get a high-end enterprise architect position, it’s time now to obtain some skills on ESB. Here is just a brief description of ESB:

Enterprise Service Bus (ESB) is a standards-based integration platform that combines messaging, web services, data transformation, and intelligent routing to reliably connect and coordinate the interaction of significant numbers of diverse applications across extended enterprises with transactional integrity.

In ESB, applications and event-driven services are tied together in a Service-Oriented Architecture (SOA) in a loosely coupled fashion. This allows them to operate independently from one another while still providing value to a broader business function.

Note: In J2EE (now called Java EE) world, Java Specification JSR 208 Java Business Integration (JBI) can be considered a Java standard for an enterprise service bus (ESB).
