Implementing Enterprise Service Bus (ESB) Architecture as a Business Model for Electronic-Commerce System

Abstract

Enterprise Service Bus (ESB) architecture is considered a platform to realize a service-oriented
architecture. An ESB brings flow-related concepts such as transformation and routing to a ServiceOriented Architecture (SOA). An ESB can also provide an abstraction for endpoints. To achieve these
objectives, this paper considered the Enterprise Service Architecture that represented the piece of
software that lives between the business applications and enables communication among them. Ideally,
the ESB should be able to replace all direct contact with the applications on the bus, so that all
communication takes place via the ESB. To achieve this objective, the ESB must encapsulate the
functionality offered by its component applications in a meaningful way. This typically occurs through
the use of an enterprise message model. The message model defines a standard set of messages that the
ESB will both transmit and receive. In an enterprise architecture making use of an ESB, an application
will communicate via the bus, which acts as a message broker between applications. Such an approach
has the primary advantage of reducing the number of point-to-point connections required to allow
applications to communicate (Erl et al, 2005).
