In the traditional software development and deployment, the centralized monolithic is always adopted, as the modules are tightly coupled, which caused many inconvenience in software DevOps. The modules with bottlenecks in monolithic application cannot be extend separately as the application is an integral part, and different module cannot use different technology stack. To prolong the lifecycle of the monolithic applications, its need to migrated it to microservice architecture. Due to the complex logic and large number of third party framework libraries depended, get an accurate comprehensive of the application characteristics is challenging. The existing research mostly based on the static characteristics, lack of consideration of the runtime dynamic characteristics, and the completeness and accuracy of the static analysis is inadequate. To resolve above problems, we combined static and dynamic analysis to get static structure and runtime behavior characteristics of monolithic application. We employed the coupling among functions to evaluate the degree of dependence, and through function clustering to achieve the migration of legacy monolithic applications and its data to microservices architecture. Through the empirical study of migrate the typical legacy project to microservices, it is proved that we proposed method can offer precise guidance and assistance in the migration procedure. Experiments show that the method has high accuracy and low performance cost.
