Enterprise Service Bus - A Backbone for SOA

摘要

Nowadays, enterprises are using multiple specialized applications to solve different aspects of their business, from simple content management systems to complex financial or business intelligence applications. These different specialized applications were developed using different communication protocols and programming languages. During time, business requirements and goals are changing continuously and along with them the application complexity is also raising. Many applications have to be integrated together in order to communicate and to share resources and data. A big help in dealing with these challenges is the new architectural style called SOA. The SOA, which can be extended also at business level, ease the bridge between business requirements and software. In order to assure a neutral language communication and resource sharing, the Enterprise Service Bus (ESB) pattern is used. In this paper we describe the main advantages of an ESB model along with its importance for a SOA approach.
