EWA viewer and workspace - Source data

Hi Experts,

I am having two solution manager systems ( 7.1 & 7.2) in the landscape.

Would like to find out which is one providing data to the EWA workspace and viewer( cloud based).

what is the source of these cloud URL's..even if the managed system is not connected, can data to go these to URL's directly.

Please clarify..

Thanks in advance
