Background: Seeking an appropriate architecture for a software design is always a challenge in recent decades. Although microservices as a lightweight architecture style is claimed that can improve the current practices with several characteristics, many practices are based upon the different circumstances and reflect the variant effects. An empirical inquiry brings us a systematic insight into the industrial practices on microservices. Objective: This study is to investigate the gap between the ideal visions and real industrial practices on microservices and what benefits we can gain from the industrial experiences. Method: We carried out a series of industrial interviews with thirteen different types of companies. The collected data were then codified according to the defined qualitative methods. Results: We characterized the gaps between the typical characteristics accepted in the community and the industrial practices of microservices. Furthermore, the compromise between benefits and sufferings of microservices around these nine dimensions were also investigated. Conclusion: We confirmed the benefits of the microservices that can be obtained from practice as well as their possible pains that need to be addressed with extra expense from experiences. Besides, some outlined pains, e.g., organizational transformation, decomposition, distributed monitoring, and bug localization, may inspire researchers to conduct the further research.
