Are there any best practices on how to bundle them to get redundancy as well as more bandwidth ideally without needing to change anything or much in case some of the connections are flaky some of the time.
I guess there are many things to consider and to potentially get wrong (that might also be super difficult to debug without understanding everything) so I would be very very grateful for experience you can share or pointers what to look for.
This is surprisingly difficult to google for (lots of SEO spam).
