I don't know Rails. I know Python and Golang. Worked in a data-intensive, data heavy startup, throwing microservices, nanoservices in a haphazard fashion with K8S backing the "throw and see something sticks" approach.

Elixir, and Phoenix makes me think. About three years ago, when we started the company, if we had these two tech... we could've been saved so much dev time focusing on the core tech, instead of making scaffolding work.

Same here. Microservices have their place if you expect to have to scale like craaaaazzzzy or if you know that your platform will be huge with many different parts but you can go a LONG way with a Phoenix monolith while being "happier" and more productive.

From my (limited) experience it's an ideal framework for startups or new web apps. I've also heard excellent things about replacing painful microservice setups with one Phoenix app.

There is just so much you can do with it at scale and also so much you don't have to do (e.g. channels + integrated pub/sub are a godsend). Definitely my new favorite framework (+ language) for web dev.
