In our article presented in ECSA (12th European Conference on Software Architecture) 2018, we show a pattern language for scalable microservices-based systems. This research is focused on organizing the existing design patterns for scalability of microservice-based systems. The following figure represents our pattern language:

The main idea to create this pattern language is to understand how architectural patterns satisfy the scalability dimensions. We realized that communication and services are the most significant components related to scalability.

We used out pattern language in a Chilean in a real-time vehicle position capturing project, obtaining encouraging results. As future work, we want to expand this pattern language considering specific design-time solutions (aka architectural tactics) as a part of the language.
