A curated List of project that migrated to microservices

A curated list of Open Source projects developed with a microservices architectural style

Table of Contents

Introduction

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
