Erlang process are inherently stateful, which makes it hard to fit it into modern deployment infrastructure such as kubernetes that works best with a stateless process. The process model also makes it very tempting to build a monolithic-microservices and build an erlang VM cluster which can add complexity if you already have an infrastructure like kubernetes or works with other languages. FWIW, these things I just mentioned can also be considered as Erlang/Elixir's strengths depending on your requirements.
