Your monolith, Elixir, and you

Elixir is great, so clearly we'll all rewrite our applications in Elixir.

Mostly, you can't and shouldn't do that.

This presentation will show you another path. You’ll see how at Liefery, Tobias and his team have started with small steps instead of rewriting everything. This allowed them to reap the benefits earlier and get comfortable before getting deeper into it.

Tobias will examine in detail the tactics they used to create two Elixir apps for new requirements, and how they integrated them with their existing Rails code base.


Join Tobias on his tale of adopting Elixir and Phoenix and see what he learned, what he loved, and what bumps he hit along the road.
