Building Moduliths That Last: Patterns for Sustainable Module Integration

Christoph Kober

Are shared database schemas turning your backend into a big ball of mud? Discover resilient integration patterns to build a modular monolith that actually lasts.

#1 about 3 min

The challenge of preventing modular monoliths from degrading

Why initially well-structured monolithic applications often collapse into unmaintainable architectures over time.

#2 about 2 min

Rule zero requires strict database schema separation

Why sharing a single persistent database schema undermines software architecture despite modularization efforts on the code level.

#3 about 4 min

Identifying tight coupling from direct module calls

An example application demonstrates how implicitly coupled elements leak internal logic and create structural rigidity.

#4 about 2 min

Using facade patterns to define explicit modular boundaries

Refactoring direct cross-module connections into explicit facades simplifies integration intent and reduces tightly linked code.

#5 about 2 min

Decoupling direct connections using the mediator pattern

Implementing an intercepting mediator routes module commands without revealing inner dependencies or operational details.

#6 about 5 min

Extracting business logic into an orchestration layer

Separating peer-to-peer relationships into a centralized coordinator clarifies long-running procedural workflows and standardizes data consistency.

#7 about 3 min

Visualizing technical integrations with standalone process engines

Adopting visual process engines abstracts away complex technical execution details but risks relocating critical business rules.

#8 about 5 min

Integrating changing module states via domain events

Using an asynchronous in-memory event stream establishes strongly isolated and highly evolvable module interactions.

#9 about 5 min

Solving display requirements through user interface combinations

Combining module elements via explicit hyperlinks and dynamic templates prevents unnecessary backend events while advancing self-contained architectures.

#10 about 3 min

Choosing optimal integration patterns for domain modularity

Practical heuristics detail how mixing explicit software contracts supports domain-specific capabilities rather than rigidly mandating a single architectural trend.
