Modular monoliths offer a middle ground between traditional monoliths and microservices by organizing applications into well-defined modules within a single deployable unit. Spring Modulith provides tools for building modular Kotlin applications with enforced module boundaries, verification tests, module-level testing, and observability features. The architecture simplifies deployment and testing while maintaining structural benefits like clear interfaces and independent development workflows, making it ideal for early-stage products, complex business domains, or teams wanting to avoid distributed system complexity.
