This document provides an overview of enterprise service buses (ESBs) and recommends WSO2 ESB as a solution. It defines an ESB and why organizations use them. Key sections explain how to select an ESB and whether an organization needs one. The document also outlines the core functionalities of ESBs in general and highlights features of WSO2 ESB like support for protocols, transformations, reliable messaging, and extensibility through the Carbon platform. It positions WSO2 ESB as a lightweight, open source solution that provides the full capabilities of an ESB.

3. ESB - What?
• Enterprise Service Bus (ESB)
• An enterprise service bus (ESB) is a software architecture for middleware
that provides fundamental services for more complex architectures.
• An ESB acts as a shared messaging layer for connecting applications
and other services throughout an enterprise computing infrastructure.
• It supplements its core asynchronous messaging backbone with
intelligent transformation and routing to ensure messages are passed
reliably.
