Propuesta de un patrón de arquitecturas de software para la interoperabilidad en dispositivos en la capa al borde de un ecosistema IoT
Get PDFEn los últimos años el Internet de las cosas ha generado una disrupción en el ecosistema
de soluciones para usuarios finales con aplicaciones en la salud, agroindustria, medio
ambiente y otras soluciones heterogéneas. Cada una de estas tienen su propio formato para
verbalizar los datos proporcionados por los diferentes servicios SOAP, RESTful, REST-LD en
formato JSON o XML que pueden ser entendidos por personas. Estos dispositivos se denominan
“heterogéneos” porque provienen de diferentes proveedores de manufactura, diferentes
lenguajes de programación como C, C++, Lua, Python, JavaScript, etc. Este documento se
enfoca sobre dispositivos restringidos, es decir, dispositivos con poca capacidad de procesamiento
y memoria con diferentes cadenas de datos sensados. Esta investigación propone un
patrón de arquitectura de software para la interoperabilidad entre los dispositivos al borde de
un ecosistema IoT y entre ecosistemas entre sí.In recent years, the Internet of Things has generated a disruption in the solution
ecosystem for end users with applications in health, agro-industry, environment and other
heterogeneous solutions. Each of these solutions has its own format to verbalize the data
provided by different web services, including SOAP, RESTful and REST-LD, in JSON or
XML format, so that said data can be understood by people. These devices are called “heterogeneous”
because they come from different manufacturers and use different programming
languages such as C, C++, Lua, Python, Javascript, etc. This document focuses on constrained
devices, that is, devices with little processing capacity and memory, and different chains
of acquired data. This research proposes a software architecture pattern for interoperability
between devices on the edge of an IoT ecosystem and between ecosystems
A comprehensive evaluation framework for system modernization : a case study using data services
Get PDFModernization is a solution to migrate cumbersome existing systems to a new architecture for improved longevity of business processes. Three modernization approaches exist. White-box and black-box modernization are distinct from one another. Grey-box modernization is a hybrid of the white-box and black-box approaches. Modernization can be utilised to create data services for a Service Oriented Architecture. Since it is unclear which modernization approach is more suitable for the development of data services, a comprehensive evaluation framework is proposed to evaluate which of the white- or black-box approaches is more suitable. The comprehensive framework consists of three evaluation components. Firstly, developer effort to modernize existing code is measured by acknowledged software metrics. Secondly, the quality of the data services is measured against identified Quality of Service criteria for data services in particular. Thirdly, the effectiveness of the modernized data services is measured through usability evaluations. By inspection of the combination of application of each of the evaluation components, a recommended approach is identified for the modernization of data services. The comprehensive framework was successfully employed to compare the white-box and black-box modernization approaches applied to a case study. Results indicated that had only a single evaluation component been used, inconclusive results of the more suitable approach may have been obtained. The findings of this research contribute a comprehensive evaluation framework which can be applied to compare modernization approaches and measure modernization success
