S. Haselböck, R. Weinreich, G. Buchgeher: An Expert Interview Study on Areas of Microservice Design, 11th IEEE International Conference on Service Oriented Computing and Applications (IEEE SOCA 2018), Paris, France, November 20-22, 2018, doi: 10.1109/SOCA.2018.00028


Microservices are an architectural style focusing on single-responsibility units that are implemented in various technologies by independent cross-cutting teams. A shift to microservices therefore touches many different areas, including system design, organizational structures, and runtime infrastructure. To investigate the importance of different areas of microservice design, we performed an interview study with 10 microservice domain experts. We tried to find out which design areas are relevant for microservices, how important they are, and why they are important. In this paper, we present the resulting microservice design areas, the assessments of their importance, and rationales for the provided assessments.
