Enterprise Integration with Messaging

Abstract

Integration architects and developers are faced with many challenges when integrating disparate enterprise applications. First off, it is necessary to come up with the integration solution that meets organization’s business needs. At the same time, they need to make sure that the solution requires minimum or no changes to the existing applications, so that cost of integration is minimal to the organization. This means the integration solution has to be technology neutral so that applications and systems built using different platforms and languages can be easily integrated. In addition, the systems integrated need to be loosely coupled so that changes to one system can be handled easily without impacting others. In order to tackle integration challenges like these, knowing and applying the appropriate integration styles and patterns is necessary. In addition, architects and developers need to be able to map different architectural design to appropriate technology and products. This thesis essay conducts a review on many of the integration architectures and patterns and how they help solve some of these challenges. It also reviews some of the technologies and products that are used to implement enterprise integration. More specifically, the essay takes an in-depth look into enterprise integration with respect to messaging by reviewing various messaging architectures, patterns, and technology. So, there are three main objectives for this thesis. The first objective is to research and evaluate some of the common integration architectures. The second objective is to review and analyze various integration patterns, specifically messaging and interaction patterns, and discuss how they help solve many common integration problems. The third objective is to discuss current technologies and products that are being used to implement enterprise integration based on proven architectures and patterns.
