The current web service exposure design results in a 1:1 ratio of process/ object to resource. This results in limited resiliency and reduces the overall usability of the Web Service functionality in an Enterprise setting.
Ideally processes & objects should be exposable onto a number of resources to provide additional resiliency - and also enable the ability to load balance any incoming requests across the various resources exposed.
Alternatively, the process/ objects should be exposed via the Application Server - where it would then be possible to select which resources could receive an incoming request.
