    Metodología para la creación de aplicaciones basadas en microservicios para soluciones de internet de las cosas en ambientes de vida asistidos
    (2018-10-29) Cabrera Alvarado, Edwin Fernando; Cárdenas Cárdenas, Paola Johana; Cedillo Orellana, Irene Priscila
    Microservices along with technologies such as Internet of Things (IoT), Cloud Computing, among others, have revolutionized the business model of companies oriented to provide assistance, monitoring and surveillance services in Ambient Assisted Living (AAL); However, the development of applications based on microservices, breaks the traditional software development scheme and even more, the organizational scheme, being an architecture that is increasingly accepted. On the other hand, the agile methodologies of software development stand out for their simplicity, both in their learning and in their application, allowing those who use them to obtain a reliable software product of quality and with a design that faces continuous changes with early deliveries; with this study the adoption of agile software development methodologies with microservices architectures is motivated and an instance of it is presented for software solutions in IoT enviroments for AAL. Consequently, this study presents MicroIoT, a methodology for the definition, creation and deployment of microservices based on agile methodologies, for IoT solutions deployed in AAL, which is aligned with the DevOps organizational approach, which adequately covers the development and operations on microservices. In addition, an IoT software system for AAL has been designed and implemented, as an instance developed with the proposed methodology. MicroIoT has been evaluated empirically through a quasi-experiment carried out with professionals and students of the Systems Engineering Carrer in the University of Cuenca.

    Towards a methodoly for creating Internet of Things (IoT) applications based on microservices
    (IEEE explore, 2020) Cabrera Alvarado, Edwin Fernando; Cardenas Cardenas, Paola Johana; Cedillo Orellana, Irene Priscila; Pesantez Cabrera, Paola Gabriela; Cedillo Orellana, Irene Priscila
    The Internet of Things (IoT) represents the new industrial revolution, in which physical and virtual objects are interconnected. On the other hand, microservices architectures have broken the monolithic and centralized way to build software, and provide systems with high-quality characteristics (e.g., resilience, availability, modularity, and portability). Therefore, the idea of merging those technologies can constitute a powerful strategy to be applied in environments that demand the distribution and management of many IoT devices using high-quality software. In this context, several studies that integrate IoT with microservices solutions have been analyzed. However, most of these studies aim to satisfy the functional requirements related to software and hardware, without taking into account software engineering methodologies and good practices that allow the creation of software for IoT devices considering their distributed nature. Thus, this paper presents the first approach to an agile methodology that i) contemplates the main characteristics of the IoT and ii) guides the development of appropriate software solutions based on microservices architectures to manage IoT environments acknowledging the serious difficulties that microservices imply.
