I'm building server software for my startup. My development environment is a linux docker container running on a linux vm running on an x86 mac. Its running the same binary as the docker container running in kubernetes on an x86 aws server.
The fact that apple is making arm mainstream means if I switch to arm, so are a lot of others working to make the arm port of my stack a first class consideration.
Suddenly the gavatron cores aws has are becoming a whole lot more viable. I personally plan to move our api instances over to them once the erlang vm's arm port matures a bit.
