Re-architecting OO Software into Microservices

Due to its tremendous advantages, microservice architectural style has become an essential element for the development of applications deployed on the cloud and for those adopting the DevOps practices. Migrating existing applications to microservices allow them to benefit from these advantages. Thus, in this paper, we propose an approach to automatically identify microservices from OO source code. The approach is based on a quality function that measures both the structural and behavioral validity of microservices and their data autonomy. Unlike existing works, ours is based on a well-defined function measuring the quality of microservices and use the source code as the main source of information.
