Design and implementation analysis of microservices architecture for enterprise management software based on DevOps

This study explores the design and implementation of DevOps-based microservice architecture for smart city enterprise management software. In the context of smart city construction, the digital transformation of enterprises puts forward higher requirements for the flexibility and scalability of system architecture, and the traditional monolithic architecture can no longer meet the business needs of modern enterprises. The research adopts Spring Cloud framework to develop the system and realizes a three-tier microservice architecture design for smart city enterprise services and divides the business tier into 12 core microservices through domain-driven design methodology. The system adopts MySQL parent-child cluster for data management and is deployed on Kubernetes platform. Jenkins is used to achieve continuous integration and deployment, and the environment consistency is ensured by Docker containerization technology, which realizes the DevOps practice of full process automation. Functional testing verifies that the functional integrity of the system reaches 99.5%, and performance testing shows that the system supports 10,000 concurrent users with an average response time of 200ms, and system availability reaches 99.95%. With the read-write separation strategy, database query performance was improved by 62% and order processing time was reduced from 15 minutes to three minutes. The system provides replicable technical solutions and practical experience for the digital transformation of smart city enterprises, and has important theoretical and practical value for promoting the construction of smart cities.
