Understanding Domain-Driven Design (DDD) in Microservices
Domain-driven design (DDD) serves as a crucial framework for establishing effective microservices by identifying service and consistency boundaries. DDD promotes the concept of bounded contexts, which are defined areas where a specific domain model is applied, helping to clarify the meanings of terms within a project. For instance, the term 'product' can have varied interpretations depending on its context—for example, a product catalog might focus on pricing, whereas an inventory system emphasizes availability. By applying DDD principles, developers can structure microservices more effectively, making it easier to address complexity and adapt to changing business requirements.
