After several questions opened in Quora[4,5,6], StackOverflow [2,3], ResearchGate [1], I decided to report the list of projects that migrated to microservices or that are implemented from scratch with a microservice architectural style. In our previous work, we investigated several microservices issues, including migration issues[10], architectural patterns[9], and bad smells or antipatterns[8]. The availability of a common data-set of projects implemented with a microservice architectural style, would be very useful to validate our results, but also to anyone who need to learn how to develop microservices-based applications or to researchers that want to study how these systems are architected.

The list could be useful to anyone who need to learn how to develop microservices-based applications or to researchers tha t want to study how these systems are architected. If you are interested to the Architecture related principles, tools and technologies, please consider this github page https://github.com/mfornos/awesome-microservices

I am still looking for a real legacy project (5-10 years old) where I can study how it evolved from Monolithic to microservices. I think this is a common issue of most of the researchers working on microservices, and if we will manage to find at least one, it could be a very good starting point.

Feel free to contribute suggesting other projects. You can send recommendations for new projects making a pull request to this page, or sending an email to davide [dot] taibi [at] tuni [dot] fi

This is the extended version of the Microservice Dataset V1.

This list is based on the feedbacks received in the different platforms [1][2][3][4][5][6] and on the list of microservices-based projects listed in scientific papers[7], and of several pull requests submitted buy different authors. I'd like to thank all the participants to the discussions and all the authors of the papers that contributed to populate this list.
