Elixir Architecture
Good Elixir architecture separates business contexts, process boundaries, and delivery concerns so OTP can do its job cleanly.
Service boundaries
Keep business logic in clear contexts and use processes for state that must live at runtime.
Umbrella apps
Umbrella projects help organize large systems into reusable apps with smaller dependency surfaces.
Deployment layout
Make release and environment decisions explicit so production behavior is predictable.
Practice
- Sketch one context boundary for an Elixir service.
- Decide whether an umbrella app fits a sample system.
- Write one note about why process boundaries matter in production.
