ESA & XI BPM??

Question

Hi,
I have been reading through the discussions on ESA and I have few questions...
As per my understanding ESA is an architecture from SAP to integrate a internal business process (between different systems with in an organization) OR an external business process which invloves external partners. This integration is made possible via implementing services which will communicate with each other. If this is true, we have XIs BPM available right now which actually takes care of this kind of integration. How is ESA or SOA going to be different or how will this new architecture make this process more robust???
Thanks

Hi
XI BPM can be used for service Orchestration  and XI BPM is modelling tool to implement ESA  .ESA and SOA goes hand in hand for an example  at more granular level  for creating a purchase order  you are converting it to a webservice then it is SOA but at enterprise level where you use this webservice as a reusable component to do process orchestration or service orchestration as in your case to achieve a more complex task then it is  ESA .The strength of ESA can be harvested best through composite application framework known as CAF  where your different datasources ,different processes can be brought together to suffice the needs of  business requirement for e.g if industry verticals you have XIEP for oil and gas,XMMI  etc so basically strength of ESA is in building composites using modelling tools where even a business analyst can work out solution using modelling tools like visual composer,guided procedures etc.It is paradigm shift to break a monolithic application to usable component block by building enterprise services which is composite of various webservices ,Hope thi helps you please do not forget to give points it inspires
