Complex and heterogeneous IT infrastructures can be found in almost every larger company. The integration of these IT landscapes is an ongoing and important issue, especially against the background of dynamic market developments and the associated need for change. The elasticity of IT infrastructures in companies is limited with increasing complexity, and the management of interfaces and point-to-point connections becomes virtually impossible. With Enterprise Application Integration (EAI), we use the approach of replacing existing point-to-point connections with centralized integration, and thus significantly reduce the number of interfaces. In contrast to traditional middleware concepts, EAI provides for integration at the business process level. This decisive advantage allows companies to achieve significantly more flexibility when it comes to changing business processes.
With each system that is connected to other systems within the framework of EAI, the potential grows to realize new value in the overall system through integration. We establish the prerequisites for aligning the IT architecture of companies that focus on change as a success factor, in a process-oriented rather than a technical way. Process-oriented integration makes it possible to connect systems logically via changeable workflows. As a result, complete business processes – across system boundaries – can be controlled temporally as well as logically, and on the basis of business rules.
