There is a good discussion related to this topic here:
Personally I am a big fan of Dave’s approach - it just ‘makes sense’ to me.
I think Dave’s point is that if you go with an Umbrella app, it is still coupled, whereas his approach of totally independent apps, are, totally independent.
I’ve not heard him call it this, but I like to refer to it (or class it as) The Replaceable Component Architecture.
I can’t wait for his next course, which I hope ties in Ecto, deployment and goes more into sharing of or interacting with various data/components etc i.e. something more typical of a bigger real life app.
