The microservice architecture provides an efficient manner to allocate computational resources since each microservice can be individually scaled. Despite its benefits, there are still challenges regarding the cooperation among different microservices in order to provide elaborated business processes. In this paper, we propose Beethoven, an event-driven lightweight platform for microservice orchestration that eases the creation of complex applications that use microservice data flows. The platform is composed of a reference architecture and an orchestration language. The reference architecture has been instantiated by using the Spring Cloud Netflix ecosystem. To demonstrate the feasibility of the Beethoven platform, an example application has been developed. All artifacts produced as part of this work are available.
