Information integration is as old as Information Technology (IT) itself. We have been doing it in multiple ways and using multiple technology stacks. But, what is more important is that, at the end of the day, the integrated solution should be solving more existing problems and introducing less new problems. This is where selecting and choosing appropriate integration architecture is most important in the IT landscape.

We have seen what ESB architecture is and how it is different from other peer integration architectures. So far so good, and today, you can read any number of documents on ESB from the Internet. We, as architects and developers now, also need to implement them in our code, not just in sketches in white papers and presentations. How can we do that using Java?

In the next chapter (Java Business Integration), we will see exactly what Java has to offer in defining ESB architectures.
