RESUMO:

The Internet of Things has changed the scope of the Internet and it has become a network connecting a myriad of devices of different types. The integration of these heterogeneous devices fosters novel services and applications, generates value-added information and actionable knowledge for the end user.  Developing IoT applications and services and fulfill their quality of service requirements, such as confidentiality, interoperability, scalability, evolvability, adaptability, and reliability pose multiple challenges. These challenges are imposed mainly by the ultra large scale of the IoT, the heterogeneous nature of applications and devices, and the highly dynamic environment. Nowadays, the microservices pattern has been successfully applied by companies such as Netflix and SoundCloud to address some of these issues in the context of cloud computing applications.  However, in the IoT field, the wide adoption of this Microservices still faces some obstacles to be solved in order to achieve the potential benefits of such approach. The goal of this work is to propose an architecture based on reactive Microservices for the development of IoT applications. The proposed architecture consists of a set of software components, tailored to meet the typical requirements of IoT applications that demand high availability. In addition, the proposal includes a software platform that materializes several of its components and help, at runtime, to meet the availability requirement of IoT applications. We applied our proposal in a real-world scenario in the field of Smart Agriculture and in a simulated scenario in the field of Smart Water. The experimental results conclude that our approach improves availability, minimizes latency and maximizes throughput, and increases accuracy significantly, in comparison to another study. We also carried out a performance evaluation from two perspectives. The first perspective is related to the evaluation of the IoT application through different deployment policies, which aimed to show how the architecture components used in microservices can impact the use of computational resources. The second perspective is related to the evaluation of the IoT application that uses the components of the proposed architecture in a scenario in which we increased the traffic of IoT data. The results of the performance evaluation in the two perspectives show that the IoT application remained functional during the analysis performed.
