Architectures and technologies for enterprise application integration

摘要: Architects are faced with the problem of building enterprise scale information systems, streamlined, automated internal business processes and Web-enabled functions, all across multiple legacy applications. The underlying architectures for such systems embodied in a range diverse products known as application integration (EAI) technologies. In this paper, we highlight some major problems, approaches issues designing EAI selecting appropriate supporting technology. tutorial presents common architectural patterns frequently used It also explains service-oriented current best practice framework EAI. then describes state-or-the-art technologies that support these styles, discusses key design trade-offs involved when an technology (including buy versus build decisions).
