I have never heard of ESP before. What is it, what are benefits of using ESP, and how does it relate to SOA?

I think you are referring to ESB (Enterprise Service Bus). You can get more info @

I believe he's referring to Event Stream Processing (ESP), which is really just another term for Complex Event Processing (CEP). In my book I document the usage of Esper, which is an outstanding open source CEP implementation. How does CEP pertain to SOA? An excellent discussion of this is provided in this  article[/url].

In the book, I describe an approach to service-enable Esper so that it can receive events via a web services call (such as through SOAP, REST, JMS etc). While SOA brings with it many benefits, one of the downsides is how to manage a proliferation of services distributed throughout the cloud. If the services emit events to a CEP as they are invoked/consumed, this helps manage your services infrastructure by identifying when anything abnormal occurs. It can also provide critical insights as to what services are being used most, and by whom.

Hope that helps!

Thanks, I'll have a look the article. So in short does it mean using ESP in SOA is for monitoring services?
