When do I need Mule ESB vs. Mule iBeans?
Mule ESB provides a standards-based and vendor-neutral ESB that enables seamless integration with existing applications, web services, business processes, and messages services. Includes a simplified programming model designed with the Java developer in mind that can easily handle the most advanced and complex integration scenarios. Mule iBeans provides very simple integration for sending a message between two services. If you do not require advanced routing, Mule iBeans are the best solution for you.
