The book describes in detail the middleware models and technologies that support these different approaches, including: To address the problem of architectural foresight, many organizations have created the role of the enterprise architect. EAI answers the problem of integrating systems and applications. First, implementing EAI requires that someone thoroughly understand the business processes in the enterprise. Before we make the business case for EAI, bt number of things should be understood.

In the past, this has been low-level play with developers working at the network protocol layer or just above, then moving to true middleware intefration such as RPCs, MOM, and transactional middleware.

The need for EAI is the direct result of this architectural foresight, or rather, the lack of it. Read more Read less. It is, at its foundation, a response to decades of creating distributed monolithic, single-purpose applications leveraging a hodgepodge of platforms and development approaches.

While the business case for EAI is clear to most people versed in the technical aspects of this discussion, it might not be as clear to those who really need to understand its value. This is due to the fact that the point-to-point middleware layer only provides a program interface, and thus the programs must change to accommodate the middleware.

Enterprise Application Integration

When using the point-to-point approach, integrating applications comes down to altering each application to be able to send and receive messages. Comprehensive, practical, and clearly written, this essential resource will help anyone involved in this important business area understand the nature of EAI, its tools and techniques, and how to apply it for a significant business advantage. The success of these smaller, more open systems was that they met the requirement of commodity computing but with a steep price–the need for integration with the existing, older system.

The “order solution” to this chaos is twofold. These 2 locations in Victoria: Perhaps more importantly, the press trumpeted the claim that the cost of applying and maintaining the newer platforms was less than traditional systems. The book describes in detail the middleware models and technologies that support these different approaches, including: An additional complication to this scenario is that IT managers must perform integration projects inside fluid environments using rapidly advancing technology.

It is not unusual for these systems to support thousands of users concurrently accessing the same application. While enterprise resource-planning applications are the leaders in the packaged applications market, many other types of packaged applications are finding their way into the enterprises.

As a result, integrating the data and processes that may exist on these desktops within the enterprise could prove to be a nightmare. I do not fault the author for not covering what didn’t exist when he wrote the book, just consider these things before making your purchase decision.

Because a sound EAI solution often requires a change in organization, the psychological considerations of the workforce and the flow chart structures of the enterprise must be handled appropriately. Most enterprises leverage many different technologies.

Indeed, that “ancient” technology has probably remained critical to the workings of your enterprise. While many different types of technologies can do this, message brokers seem to be the preferred solution.

As a result, there were no open application programming interfaces APIsopen architectures, or other mechanisms that allowed for ready access to the processes and data that existed within these stovepipe systems.
