Onion, Hexagonal, Clean or Fractal Architecture? All of them, and more! - Urs Enzler

Onion, Hexagonal, Clean, or Fractal Architectures aim to organize how we deal with dependencies in our software architectures. But which one should we choose? After distilling the essence of each approach and comparing the advantages and challenges, I’ll show how to combine all of them into an approach to use evolutionary steps towards an architecture that fits your needs from day one until the software dies. You’ll see that layers and slices aren’t enough. A modularisation that fits the domain and simplifies understandability, changeability, and extensibility must go beyond these concepts.
