Research on Evaluation Model of Microservice Transformation Based on Business Consistency

When enterprises transition to microservices architecture, ensuring business integrity and service interaction consistency is crucial. However, traditional approaches lack systematic evaluation of governance strategies and fault tolerance mechanisms. This paper proposes a business consistency-oriented evaluation framework integrating three core modules: business contract mapping, service stub validation, and environment simulation testing. By defining service interaction rules through YAML contracts, we implement automated traffic management testing using Istio. Network latency and service downtime are injected through Chaos Mesh to verify circuit breaking accuracy and recovery efficiency. Experimental results demonstrate that our framework effectively safeguards business process integrity, ensures service interaction accuracy, and significantly enhances fault recovery capabilities. This research provides quantifiable assessment tools and reproducible implementation schemes for microservice transitions.
