Abstract

This paper is a comprehensive introduction to the Enterprise Service Bus (ESB), which is a new type of integration infrastructure. Therefore it gives a detailed introduction into the background of Enterprise Application Integration (EAI) and explains Message-Oriented Middleware (MOM) and Service- Oriented Architecture (SOA) which are the technologies the Enterprise Service Bus evolved out of. After discussing core ESB concepts and typical features, the open source ESB solution Mule will be presented. An example application will demonstrate how different features of an ESB are used.
