1. When the Microservices Dream Becomes an Operational Nightmare
Premature microservices introduce distributed transaction failures, network latency tax, and massive DevOps overhead. The Saga pattern and distributed tracing add immense complexity without tangible business value.
2. The Stilmerce Solution: NestJS Modular Monolith
A Modular Monolith enforces strict domain boundaries, private data access, and decoupled interfaces, while executing inside a unified, zero-latency runtime.
3. Code-Level Domain Isolation and Boundary Enforcement
NestJS module boundaries guarantee that private entity repositories cannot be accessed across domain boundaries, maintaining pure architectural decoupling.
4. Architectural Comparison: Microservices vs Modular Monolith
A modular monolith provides sub-millisecond inter-module communication, true ACID transactions, and zero developer friction during local debugging.
