The concept of microservices in the software development industry is getting growing attention nowadays. This architectural style is widely discussed both in industry and academia. Refactoring a monolithic application into a microservice application is common practice. Nevertheless, software architects and developers often find it diffcult because they lack a structured overview of various migration approaches. Even though literature views about microservice migration were conducted [33][83], they were either obsolete or did not follow a systematic approach to ensure correctness and reproducibility of results. The goal of this study is to provide a classification framework as well as a web-based tool that can guide software architects and developers to comprehend up-to-date migration approaches and select a suitable one according to their requirements. In order to achieve this, a systematic literature review was conducted, resulting in thirty-one contributions from 2017 to 2020. Next, a web-based tool was developed based on the knowledge repository created after review. An evaluation of the developed tool by experts and students in the field revealed that it was able to serve the predefined purpose. The proposed framework, as well as the web-based tool, can provide the users a comprehensive overview of microservice migration and various practical approaches.
