Abstract: Software industrial practices decouple legacy software systems into microservice architectures to improve software
maintainability and to achieve faster market delivery. Evaluating microservice code maintainability during the development 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, a multi-sourced feature space model is proposed to unify the representation of software multi-sourced data.
Based on this model, a microservice maintainability measurement system is established with comprehensive metrics, in terms of the
