This paper examines the evolving landscape of microservices architecture through a comparative analysis of Domain-Driven Design (DDD) and Service-Oriented Architecture (SOA). As businesses demand agility, scalability, and maintainability in software systems, microservices have emerged as a powerful solution by decomposing applications into independent, self-contained services. This study investigates how DDD and SOA influence the design, development, and deployment of microservices. While SOA emphasizes loosely coupled services and reusability, DDD focuses on modeling complex business domains and aligning software design with business strategy. Through an analytical review of existing literature, industry case studies, and practical implementations, the paper identifies the strengths and limitations of both approaches. It highlights how DDD’s strategic design principles facilitate the identification of bounded contexts and aggregate roots, which are crucial for defining clear service boundaries. Conversely, SOA’s emphasis on service contracts and standardized communication protocols promotes interoperability among heterogeneous systems.
