Towards the Detection of Microservice Patterns Based on Metrics.

Microservices is a popular architectural approach for complex systems in companies, despite its nature of decentralization. There is a comprehensive set of microservices architectural patterns that guides implementations and helps developers to overcome issues. However, the community still scarcely adopts these patterns and only has a theoretical understanding of them. In this work, in order to increase awareness of such patterns and provide aid to developers to better understand an architecture based on microservices, we propose a detection approach based on metrics for microservices patterns. We focused on structural or architectural patterns, and implemented detection for five of them. We conducted two case studies with real-world applications and evaluated the accuracy and applicability of our approach with the developers of those applications.
