Today’s interconnected world requires that organizations rapidly deliver flexible-integrated solutions. The conventional approach is to integrate heterogeneous applications using web services but unfortunately that tends to tightly couple those applications.

In this presentation we explore three popular architectural styles including Message Oriented, Service Oriented, and Resource Oriented Architecture that are used to achieve Enterprise Integration Agility. In addition, I provide examples of each architectural style using Apache ActiveMQ, Mule ESB, and NetKernel.
