In order to provide complex and elaborated functionalities, Microservices may cooperate with each other either by following a centralized (orchestration) or decentralized (choreography) approach. It seems that the decentralized nature of microservices makes the choreography approach more appropriate to achieve such cooperation, where lighter solutions based on events and message queues are used. However, orchestration through the usage of a process model makes it is easier to analyze the flow of the composition when modifications are required. In order to benefit from the goodness of these two approaches, this paper presents a hybrid solution based on the choreography of business process pieces, that are obtained from a previously defined description of the complete microservice composition. To support this solution, the EUCalipTool platform is presented.
