In the DataOps Platform, all pipeline state is managed by Control Hub. As a result, the main reason to divide up Dev/UAT/Prod/etc. is to mitigate issues where one environment affects another (e.g., a Dev SDC going down won’t affect your Prod jobs). Having one server host two environments opens you up to the very problem you’re trying to solve, so don’t do it.

thanks for reply.

1 DC install for 1 server. is the best option. correct ?

Yep.
