I would like to have an elaborate explanation for my below queries:-
Does XI has the ability to integrate with a Webservice with minimum changes to out of the box application?
Does XI has the ability to prove robust performance and scalability characteristics. If so what are those?
If XI and R/3 are installed in the same box, how does a RFC scenario need to be designed.
Why should XI be installed in a separate box, if it can still be installed within R/3 or CRM or SRM or etc.....
Appreciate elaborate answers with examples.
