"Looking at the screen of my laptop, I realized that it was full of code that didn't let me understand what it did regarding business logic. From that moment I began to search until I discovered the architecture that decouples the business logic from the Hexagonal Architecture, more correctly called Ports & Adapters. From that moment until now, I haven't stopped reading and learning about this pattern."

Simple yet good. Explanation what Ports and adapters is and what it isn't from the first hand. I like the style how Alistair explains the history behind the pattern and the trade-offs with naming conventions.
