Cloud computing provides a pretty new and efficient way to deploy scalable web application. In this way, it can allocate their computing resource on business requirements for enterprise applications. Micro-service architecture is used to split large applications into a series of small modules that can be developed, tested, deployed, operated and upgraded independently. Micro-service architecture provides a more efficient way for a large number of Internet companies to expand their applications in the cloud, reduce complexity of application development and gain agility. In this paper we analyze and test the micro-service architecture model in a specific case-we develop and deploy the enterprise application system in the cloud to implement performance tests of two architectures (single-mode architecture and micro-service architecture mode), and we can acquire the evaluation result. These results have some guiding significance for solving the problems that may be encountered in the micro-service application of enterprise application.
