Software industrial practices decouple legacy software systems into microservice architectures to improve software maintainability and to achieve faster market delivery. Evaluating microservice code maintainability is a critical issue, facing the difficulties of multi-sourced data and diverse concerns of maintainability. By analyzing source code, code execution trace, and code revision history, we propose a multi-sourced feature space model to unify the representation of software multi-sourced data. Based on this model, we establish a microservice maintainability measurement system with comprehensive metrics, in terms of the concerns of functionality, modularity, modifiability, and interaction complexity. Accordingly, we also implement a tool prototype called MicroEvaluator, and carry out experimental analysis on open-source software systems.

Please see our paper for details: Jin WX, Zhong DH, Zhang YY, Yang MF, Liu T. Microservice Maintainability Measurement Based on Multi-sourced Feature Space[J]. Journal of Software, 2021, 32(5): 1322-1340
