>"Use One Big Database."

I do, it is running on the same big (relatively) server as my native C++ backend talking to the database. The performance smokes your standard cloudy setup big time. Serving thousand requests per second on 16 core without breaking sweat. I am all for monoliths running on real no cloudy hardware. As long as the business scale is reasonable and does not approach FAANG (like for 90% of the businesses) this solution is superior to everything else money, maintenance, development time wise.
