Explanation:
* An enterprise service bus (ESB) is a software architecture model used fordesigning 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
thefeatures 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.
