Meta-Model Approach of Applied Devops on Internet of Things Ecosystem

摘要

DevOps is a software development and distribution process. It combines an entire culture of collaboration and fusion between management approach, technologies of coding and technics of integration. DevOps is a new paradigm and novel concept that is introduced in different industries that concerns software and embedded development like robotics and smart agent.The ecosystem of the Internet of Things is a set of physical devices such as sensors and actuators. It includes a set of servers and gateways that provide connectivity. These devices can be installed at three levels: the edge level, the fog level and the cloud level. Applications that monitor things and collect data from sensors are deployed at the edge, fog and cloud levels. These applications can be containerized and deployed in different devices by Docker, which takes advantage of its advantage to create executable containers that are isolated from each other. This paper presents a generic metamodel of the Internet of Things ecosystem based on microservices and supported by Docker as a containerization tool and Ansible as a monitoring tool. This metamodel allows us to generate a system of connected objects that can be deployed on three levels: Fog, Edge, Cloud. This metamodel can be used in different types of domains such as Smart Home - Smart City - Smart Vehicle - Smart Health - Smart Farm - Smart Factory. The metamodel proposed in this article is a fusion between 5 metamodels: Internet of Things - Microservices - Ansible - Docker - Kubernetes.
