The speaker shares her 15-year journey with Domain-Driven Design and introduces the core goal of creating sustainable software architectures that last.
Sustainable architecture enables teams to consistently deliver new features over time by avoiding the structural decay that slows down development.
Splitting a monolithic application into microservices without first establishing clear modules creates a distributed big ball of mud, which is worse than the original system.
The primary goal of software architecture is to achieve high cohesion within modules and low coupling between them, which is best accomplished through a domain-driven approach.
A common anti-pattern is a single, shared domain model that creates tight coupling across the entire system, making it impossible to separate into independent modules.
Domain-Driven Design's strategic design provides a framework for decomposing a system into bounded contexts that align with business subdomains, enabling independent development.
The Domain Storytelling technique helps identify natural boundaries within a business process by mapping out actors, work objects, and activities.
A good architecture is structured around business capabilities (bounded contexts), while a poor, entity-driven architecture creates unnecessary coupling between services.
Identify potential domain boundaries by looking for one-way information flows, different process rhythms, varying definitions of key concepts, and existing organizational structures.
The Modularity Maturity Index (MMI) offers a concrete metric to evaluate a system's architectural health, which can be analyzed using specialized tools.
The speaker answers audience questions about avoiding copy-paste models, handling shared functionality, starting new projects, and event-driven architecture.
