How to set up a canton domain in different machine and connect participant nodes sequencer to that domain?

Hi, @harikrishna_sri_ramo and welcome to the forums! Yours sounds like an exciting project.

I wonder if this post would be of any help. It does not include the Besu piece, but at least it has some example config files. Getting three Canton nodes up-and-running within Docker containers really helped me work through some of those details.
