Abstract

As organizations increasingly shift away from traditional monolithic architectures, the requirements for scalable, flexible, and maintainable software systems have led to microservice architecture adoption. However, microservices’ complexity and operational overhead have presented significant challenges, particularly in managing distributed systems, inter-service communication, and deployment processes. In response, modulith architecture has emerged as a middle-ground approach, offering the benefits of modularity and scalability while mitigating some of the drawbacks of monolithic and microservices architectures.This paper comprehensively reviews the factors influencing the adoption of modulith architecture over microservices. The study identifies key drivers such as dependency management, scalability, deployment efficiency, and system availability through a detailed analysis of existing literature, case studies, and expert opinions. The review reveals that modulith architecture offers a simpler, more maintainable solution that preserves modularity without the complexity of fully distributed systems. The findings offer critical insights for software architects and organizations considering architectural transitions, positioning modulith as a viable alternative in scenarios where microservices may introduce unnecessary complexity. This research contributes to the ongoing discourse on software architecture by providing a nuanced understanding of the trade-offs involved in adopting modulith architecture. It proposes a set of considerations for organizations navigating the evolving architectural landscape.
