The Sonic ESB: An Architecture and Lifecycle Definition
Enterprise service buses (ESBs) are essential to the IT infrastructure supporting service-oriented architectures (SOA). ESBs connect, mediate and control all communications and interactions between services, and provide error and exception processing.
Given the importance of the ESB to SOA implementation, it is important to understand the functions and structure of the ESB and how its design permits rapid change, easy connections, and clear visibility and control of services and processes in SOA-based applications. This whitepaper provides a thorough definition of the ESB, including complete UML diagrams that provide a conceptual view of the ESB components.
