Enhancing the Successful Microservices Implementation

Despite the widespread adoption of microservices across major global companies, a knowledge gap persists between best practices and real-world implementation challenges faced by practitioners. While existing literature provides extensive coverage of microservices patterns, limited evidence exists regarding how the practices are actually implemented in various organizational contexts. Thus, this study aims to address this gap through a systematic synthesis of empirically-validated microservices practices from recent peer-reviewed literature. We conducted a comprehensive systematic literature review and ultimately included thirty-four high-quality articles published between 2021 and 2025. We extracted 114 microservice practices and classified them into eight domains, which are Architecture and Design, Communication and Integration, Development and Deployment, Monitoring and Observability, Testing and Quality Assurance, Migration and Legacy Modernization, Security and Access Control, and Team Organization and Development Process. Architecture and Design practices and Team Organization and Process collectively account for nearly half of all identified practices, while Security and Access Control emerged as a significant research gap, with only 5.9 per cent of studies addressing this domain. To the best of our knowledge, this is the first systematic literature review that comprehensively synthesizes microservice implementation practices across multiple domains with explicit empirical validation in real-world contexts as inclusion criteria. This study provides a comprehensive catalogue of empirically-validated practices, offering structured guidance for practitioners and a foundation for future development of microservice implementation guidelines, contributing to more successful microservice projects and mitigated implementation risks.
