Open Host Services in Domain-Driven Design | Strategic DDD & Context Mapping Explained
In this video, we break down the concept of Open Host Services in Domain-Driven Design (DDD), a powerful pattern within Strategic Design and Context Mapping.
Open Host Service refers to a well-defined, shared interface offered by one bounded context for use by others. It allows external systems to interact in a standardized, decoupled way—promoting scalability and clarity in integration boundaries.
You'll learn:
What Open Host Services are in DDD
When and why to use them between bounded contexts
How they enable extensibility without tight coupling
Real-world examples and practical guidance
This is ideal for system architects and backend developers working with APIs, modular systems, or service boundaries in complex domains.
