WPS server and Rules Server

I need to connect to Rules Server through WPS server(Single server located at offshore).

we have single process server that is being used by all to test the process components.
when we test the process components that invokes the rule service we have to use this WPS Server (Test Server) and I have not idea how we are going to use this, whether we have to deploy all process components here in the Test Server or we have to make a call to this Test Server by other system i.e. is being used during development.

how to manage payload if we use single process server?

pls suggest me better technical solution on above mentioned context.

Thanks in advance.
