Abstract

Microservices need to be composed in order to provide their customers with valuable services. To do so, event-based choreographies are used many times since they help to maintain a lower coupling among microservices. In a previous work, we presented an approach that proposed creating the big picture of the composition in a BPMN model, splitting in into BPMN fragments and distributing these fragments among microservices. In this way, we implemented a microservice composition as an event-based choreography of BPMN fragments. Based on this approach, this work focuses on supporting the evolution of a microservice composition. We pay special attention to how a microservice composition can be evolved from the local perspective of a microservice, since changes performed locally can affect to the communication among microservices and as a result in the integrity of the whole composition. We present an evolution protocol that allows a microservice composition implemented as an event-based choreography of BPMN fragments to evolve from the local perspective of the composed microservices.
