The term "Enterprise Integration Patterns (EIPs)" refers to a vocabulary of solutions to common problems in the integration of enterprise systems. Of such vocabularies pattern languages may be constituted to allow complex business flows of diverse form to be described and handled in a uniform way. Apache Camel is a framework that implements EIPs around a common interface based on Java Message Objects. Camel also provides an IDE-friendly declarative Domain Specific Language (DSL) oriented around this interface, which enables integration flows between disparate systems ("Camel routes") to be described neatly as Java Messages passed around between chained camel methods. The specifics of the underlying communication protocols (FTP, http, ActiveMessageQueue etc) are abstracted away and the flow of information is cleanly described, leaving such considerations as availability, load balancing, validation, security as the primary factors influencing the middleware's architectural complexity. In this thesis production deployments of Java Spring middleware utilizing Apache Camel will be studied. The most commonly used EIPs' Camel implementations will be inspected, and a comparison with more established integration tooling will be made when convenient, to ascertain the benefits of the Message-Oriented Middleware (MOM)-backed Camel DSL approach.
