Painful framework migrations. Difficult unit testing. Updating business logic code when changing data sources. Sound familiar? If so, then Hexagonal Architecture can likely help!

In this talk we'll start with a simple service that is coupled to its database and refactor it, step by step, to match the Hexagonal Architecture paradigm. Along the way we'll also learn about domain modeling, system architecture, and dependency management. We'll have actionable takeaways that you can use to start designing your system in a more flexible and maintainable way.
