A Unified Messaging-Based Architectural Pattern for Building Scalable Enterprise Service Bus

Abstract

Service-oriented architecture (SOA) has become the popular methodology to build large enterprise systems. Inside an enterprise, an enterprise service bus (ESB) has provided a reliable and efficient solution to have services and applications communicate with each other. This paper proposes a unified architectural pattern for building a scalable enterprise service bus which relies on messaging middleware that aims at fulfilling the different requirements of the business, while maintaining compatibility of the already deployed services. By analyzing different scenarios and business requirements, the proposed architectural pattern can save time, funds, and development effort needed to extend the currently deployed services in the enterprise.
