What is ESB Why do we go for ESB and its features?

An Enterprise Service Bus (ESB) is fundamentally an architecture.

It is a set of rules and principles for integrating numerous applications together over a bus-like infrastructure.

ESB products enable users to build this type of architecture, but vary in the way that they do it and the capabilities that they offer..
