Microservice architectures are a popular approach for modernizing legacy monolithic systems. However, transforming an existing monolith into microservices is a complex task for developers. In practice, developers typically perform the decomposition iteratively, extracting one service at a time. Unfortunately, most existing tools do not adequately support such extraction tasks, as they aim to transform a monolith into microservices architecture at once. This paper presents Extract, a prototype tool that aligns with the developer's individual workflow for performing a single microservice extraction task. Extract empowers developers to analyze the particular classes and methods within the monolith that they intend to migrate to a new microservice. Moreover, it offers human-in-the-loop support, allowing developers to make well-informed decisions regarding the extraction process and explore alternative designs. We evaluate Extract with four case studies involving open-source monolithic applications. These studies serve to demonstrate how the approach aids developers in making practical decisions during the extraction process. Furthermore, we compare the outcomes of Extract's service designs with manually decomposed microservices for further analysis.
