Domain-Driven Design for a Modular Monolith: Bridging the Gap Between Microservices and Monoliths

Trying to migrate but don’t know how to get started? Maybe a modular monolith, aka Modulith, is the answer. A modular monolith is a monolith that is divided into modules, each with its own bounded context, and designed to be loosely coupled with other modules. In this article, we’ll discuss the challenges of transitioning from a monolithic to a microservices architecture, how a modular monolith can help, and how Domain-Driven Design (DDD) can be used to support it. Challenges of transitioning include complexity, distributed system, data management, and testing and deployment.
