Abstract: The microservice architecture reconstructs the enterprise-level service capability by splitting the system functions,and the problems of weak business isolation,high system coupling,high code maintenance cost and poor scalability existing in the traditional single application architecture is solved.The basic concepts,composition,advantages and implementation methods of microservice architecture is introduced,and the design and application scheme of microservice architecture in laboratory information management system is proposed.The laboratory information management system combined with the microservice architecture can effectively ensure the sustainability of enterprise business and improve enterprise management capabilities.

Key words: Microservice architecture, Spring Cloud, LIMS(Laboratory Information Management System)
