Overview: An Enterprise Service Bus (ESB) is a distributed, message-based integration solution based on open standards. The role of an ESB is to facilitate reliable communications between IT resources such as applications, platforms and services that are distributed in multiple systems throughout an enterprise. As IT departments increasingly focus on designing SOAs to lower development costs and increase business agility, ESBs are a key first step in setting up an enterprise SOA. ESBs form the foundation of the SOA. This paper briefs about the requirements for an ESB that can address the needs of an enterprise-ready SOA.
