Increasing MOM Flexibility with Portable Rule Bases

Message-oriented middleware (MOM) provides an effective integration mechanism for distributed systems, but it must change frequently to adapt to evolving business demands. Content-based routing (CBR) can increase the flexibility of MOM-based deployments. Although centralized CBR improves a messaging solution's maintainability, it limits scalability and robustness. This article proposes an alternative, decentralized approach to CBR that uses a portable rule base to maximize MOM-based deployments' maintainability, scalability, and robustness
