The principles of service-orientation are independent of any vendor, product or technology. 

EAI: Enterprise Application Integration (EAI) is an integration framework composed of a collection of technologies and services which form a middleware or “middleware framework” to enable integration of systems and applications across an enterprise.

ESB: An enterprise service bus (ESB) is implementing a communication system between mutually interacting software applications in a service-oriented architecture (SOA).
