The biggest thing that this does is give you first class access to the ecosystem APIs and with native setups for AppEngine (Heroku-ish), Compute Engine (do it yourself on a VM) and a provider in Gigalixir which runs on GCP that gives a Heroku-like experience but is tailored specifically to everything Elixir needs (hot loading, clustering out of the box, etc).
Between those two things, GCP is pretty strong.
I was reading up on Gigalixir thanks to this thread, is it basically a more "batteries included" version of AppEngine specifically targetted for Elixir?
It’s just nice to see a hosting option that tailors itself to the more unique needs of the BEAM when the rest of the industry is focusing on stateless containers.
