What is the relationship between bounded contexts and modules in the Architecture Canvas?

The relationship between bounded contexts and modules in the Architecture Canvas is that bounded contexts define logical boundaries while modules implement functionality. Bounded contexts are a core concept in Domain-Driven Design (DDD) and help clarify the scope of different parts of the system by establishing clear boundaries for the models, business rules, and language used. Each bounded context encompasses a specific part of the domain and allows teams to work independently on the different contexts.

On the other hand, modules serve as implementation units that contain the actual code and functionality needed to fulfill the requirements of the bounded context. They can be seen as the tangible realization of the logic and operations defined within a bounded context. Therefore, while bounded contexts focus on the conceptual architecture and separation of concerns, modules deal with the practical implementation of features and services that reside within those boundaries. This relationship ensures that the system remains modular and maintains clear separation between different aspects of the business domain.

The other options do not accurately capture the essence of the interaction between bounded contexts and modules and fail to reflect the principles of DDD and architectural design.
