Abstract
Nowadays, the concept of “Everything is connected to Everything” has spread to reach increasingly diverse scenarios, due to the benefits of constantly being able to know, in real-time, the status of your factory, your city, your health or your smallholding. This wide variety of scenarios creates different challenges such as the heterogeneity of IoT devices, support for large numbers of connected devices, reliable and safe systems, energy efficiency and the possibility of using this system by third-parties in other scenarios. A transversal middleware in all IoT solutions is called an IoT platform. the IoT platform is a piece of software that works like a kind of “glue” to combine platforms and orchestrate capabilities that connect devices, users and applications/services in a “cyber-physical” world. In this way, the IoT platform can help solve the challenges listed above. This paper proposes an IoT agnostic architecture, highlighting the role of the IoT platform, within a broader ecosystem of interconnected tools, aiming at increasing scalability, stability, interoperability and reusability. For that purpose, different paradigms of computing will be used, such as microservices architecture and serverless computing. Additionally, a technological proposal of the architecture, called SEnviro Connect, is presented. This proposal is validated in the IoT scenario of smart farming, where five IoT devices (SEnviro nodes) have been deployed to improve wine production. A comprehensive performance evaluation is carried out to guarantee a scalable and stable platform.
Highlights
Over the last decade, the Internet of Things (IoT) paradigm has been applied to a wide variety of scenarios, including smart cities [1], health [2], transportation, industry and agriculture, among others [3,4]. the authors of [5] note that the number of devices connected to the Internet will reach2.3 trillion by 2025
We can see that the maximum value (2472 msg/sec) and maximum average (1994 msg/sec) are reached with 25 IoT devices and a rate of 200 msg/sec sent from each IoT device
From 25 IoT devices, the number of messages is decreased, and other rates follow this pattern. This is not due to lack of scalability of the IoT platform, because, as we will see in the CPU and RAM tests, they are not affected excessively. the reason is that the computer used to run the experiment cannot compete against the observations ingestion rate of the server
Summary
The Internet of Things (IoT) paradigm has been applied to a wide variety of scenarios, including smart cities [1], health [2], transportation, industry and agriculture, among others [3,4]. the authors of [5] note that the number of devices connected to the Internet will reach2.3 trillion by 2025. The authors of [5] note that the number of devices connected to the Internet will reach. The platforms that manage IoT solutions are inherently distributed due to the existence of a vastly diverse range of devices [8]. Such devices carry certain limitations in terms of energy and processing capacity, as well as low storage capacity [9]. Usually each device has a simple task, such as Act or Observe, behind them, there are business applications with more ambitious objectives These business applications configure and deploy IoT devices to follow a strategy in order to reach a final goal
