Because the Erlang VM can run multiple different fully independent applications, it seems tedious to spin up 5 different Erlang VM’s to do different things when it could all be accomplished on one.

I wonder in Erlang terms of 'application',  if running multiple
applications in one single Erlang VM,   are there any ways to
configure resource restrictions to each application,  at OTP
Supervisor tree level  ?   like how much memory can it use at most,
and CPU, network, ... etc
