Radha,

 

I think this depends somewhat on your pricing model.  For example - if it is access based - then accounting may occur at the registry - that manages active accounts for the month / period.  If accounting occurs based on successful business transactions completed - then it would be in the backend - when the transaction is verified as complete.  If its based on the traditional VAN model of bytes transacted - then ESB hook makes sense.

 

For me - the key is to have a pluggable architecture - so its easy to add these domain specific tools in a *consistent* way that allows seemless re-use driven by simple XML-script / configuration control.

 

This takes you away from systems of today - that have hardwired coding everywhere - and therefore the infrastructure cannot easily be shared, re-purposed or quickly adapted.  Ease of change is critical factor - of course anyone can change code and re-build - given enough time, resources and testers.  What we sorely need is ability to manage and implement change easily with minimum resources.
