Models vs Bounded Contexts for Domain Modularization

Bounded Contexts are often considered the go-to solution for modularizing business logic – a key challenge in building maintainable systems. But in practice, the concept of a “Bounded Context” is complex and not always easy to implement.

In this talk, we explore how models can serve as a practical tool for identifying the different parts of a domain. While Domain-Driven Design highlights models—placing them at the heart of Bounded Contexts—they can also be valuable beyond that. Especially when combined with concepts like modules or abstract data types, models offer a powerful approach to structuring domain logic.
