Chapter 3. Enterprise-Scale Solutions in... > Enterprise Application Integration

3.4. Enterprise Application Integration

The application server is simply one piece of the solution to a much broader problem facing many organizations. In solving their IT problems, many organizations find that now their IT infrastructure consists of a puzzling collection of packaged applications, deployed mainframe systems, plus a variety of homegrown corporate and departmental utilities. Although they've solved many of their near-term IT needs, they are also finding that they face a growing problem with a key corporate IT need: connecting these solutions for a consistent view of their IT assets. One answer is to combine these isolated solutions to provide increased productivity and business intelligence to corporations. The broad term Enterprise Application Integration (EAI) covers the various aspects of this approach.

Consequently, if you open any magazine on application development, it's likely that you will see at least one article on EAI. However, as with most new approaches, the concept of EAI is a mixture of existing technologies and new perspectives, wrapped up with a large dose of marketing hype. It is important to look at a number of broad aspects of the EAI approach and their impact on enterprise-scale solutions as a whole.
