Licensing might need to be considered for this - normally a DMA is licensed to a single customer. I think https://shares.dataminer.services/ would eventually allow to share screens between 2 or more customers who have already their own licensed DMS.

Wheather it's viable or not... could eventually depend on the level of "segregation" required: you can surely have each user/customer connecting to a central DMS, to land and see only the assigned set of views. SRM or Router Control modules may still be global when accessed through surveyor - worth testing if some separation can be implemented there just with user settings (e.g. showing only specific pages of the Router Control App).

The level of concurrent access may play a role - so a dashboard gateway could come in handy (it used to be a component with a separate license), as well as a load balancer (how many requests should the web server handle?).

HTH,
