And to further add to this. When he says "same benefits of microservices within a single app", that's because there's this concept of an "Umbrella app".

Basically you could split up your apps and hack on them independently (but actually have a good way to share dependencies if needed) and at deploy time you could choose to deploy all of them, or just the ones you want.

Phoenix (Elixir's goto web framework) also tries to nudge you in a good direction to split up your code base in a way that allows you to separate the specific pieces of your app. This is really good for people who just want to make maintainable projects. It's sort of like the first step in splitting up your application without dealing with any type of real additional complexity since changing things around just involves renaming and moving files.
