Arquitetura orientada a eventos: mapeamento sistemático e estudo de caso de aplicação prática

Abstract

According to recent studies, event-driven architecture (EDA) has been widely adopted by the software industry in recent years, a phenomenon boosted by the growing use of microservice architecture in software development. In this context, EDA is used as a communication mechanism between system components, based on the emission of events. An example of this is the company Spotify, which uses this approach to deliver events. In view of this, with the aim of exploring the applicability scenarios of EDA, as well as the tools used in its implementation, this study carries out a systematic mapping of the literature, structured in three stages: planning, conducting and reporting. To answer the research questions, 200 papers were analyzed, identifying that the architecture can be applied in scenarios that require real-time processing, systems that require scalability or modularity, integration of distributed systems and the Internet of Things (IoT), as well as management of complex workfl ows, simulations and modeling in dynamic environments. In addition, the study shows that the three most common tools for implementing EDA are Apache Kafka, RabbitMQ and Mosquitto, respectively. As a practical contribution, the work includes an open-source project containing tutorials that demonstrate examples of the use of these tools in the application of EDA, with the aim of helping students in the fi eld
