* An enterprise service bus (ESB) is a software architecture model used for designing and implementing the interaction and communication between mutually interacting software applications in service-oriented architecture (SOA). As a software architecture model for distributed computing it is a specialty variant of the more general client server software architecture model and promotes agility and flexibility with regards to communication and interaction between applications. Its primary use is in enterprise application integration (EAI) of heterogeneous and complex landscapes.
* An enterprise service bus (ESB) is a software architecture for middleware that provides fundamental services for more complex architectures. For example, an ESB incorporates the features required to implement a service-oriented architecture (SOA). In a general sense, an ESB can be thought of as a mechanism that manages access to applications and services (especially legacy versions) to present a single, simple, and consistent interface to end-users via Web- or forms-based client-side front ends.
