A good microservice architecture won't have an external call result in multiple serde bounces between other microservices before a response is returned. At worst it should wrap access to something slow like a database or another complicated backend service. >Functional programming lets you achieve the same isolation benefits as microservices without the overhead. Isolation benefits, sure. Performance benefits, no, because you still run into https://en.wikipedia.org/wiki/Amdahl%27s_law https://en.wikipedia.org/wiki/Amdahl%27s_law
