It’s all about the domain, honey ! Experiences from 15 years of Domain-Driven Design

Carola Lilienthal

Are your microservices just a poorly managed distributed monolith? Discover why fifteen years of Domain-Driven Design proves that intentional boundaries are the true key to sustainable software architecture.

#1 about 8 min

Building and maintaining sustainable software architectures

Maintaining a steady stream of feature delivery over multiple releases requires continuous attention to structural health and refactoring.

#2 about 4 min

Microservices and the distributed big ball of mud

Cutting a highly coupled monolith into networked pieces fails unless internal modularity and dependencies are properly resolved beforehand.

#3 about 2 min

Designing for high cohesion and loose coupling

Dependency control forms the core of sustainable design by defining a clear separation of concerns within and across modules.

#4 about 6 min

Resolving entangled domain models in legacy applications

Grouping software by use cases instead of business capabilities often results in deeply tangled core domain classes.

#5 about 4 min

Defining subdomains and bounded contexts in software

Strategic design sets explicit boundaries around small domain components to isolate requirements and empower independent engineering teams.

#6 about 5 min

Using domain storytelling to discover architectural boundaries

Recognizing distinct business triggers and one-way information flows helps locate natural architectural cuts in complex organizational workflows.

#7 about 6 min

Implementing distinct domain boundaries without tight coupling

Restricting module communication to asynchronous updates prevents the operational tight coupling caused by shared synchronous entity services.

#8 about 5 min

Evaluating codebases using the Modularity Maturity Index

Quantifying code structure provides an objective metric for evaluating how effectively an application separates independent business concepts.

#9 about 8 min

Managing domain duplication and evolving early architectures

Starting projects as well-structured monoliths allows domains to mature before teams implement complex microservices or event-driven communication layers.
