Please note this architecture diagram is not tied up with implementations of Microsoft, IBM etc. It’s a general architecture. Any vendor who implements SOA needs to fulfill the below SOA components. How they do it is completely their own technological implementation.

The main goal of SOA is to CONNECT disparate systems. In order that these disparate systems WORK they should message each other. ESB (Enterprise Service Bus) acts like a reliable post office which guarantees the delivery of messages between systems in a loosely coupled manner. ESB is a SPECIAL layer which delivers messages between applications. In the figure we have shown a huge plump pipe. It’s not hardware or some wire etc. It’s a group of components/software which helps you send and receive messages between the disparate applications. Do not try to CODE your own ESB, you can think of buying one from Microsoft, IBM, Oracle, Progress, etc.
