IoT use cases span a variety of sectors and businesses. A typical Internet of Things (IoT) solution consists of a large number of heterogeneous IoT devices with sensors that generate data in a variety of formats at varying rates, which is then processed and analyzed to derive insights. In addition, IoT devices can connect to a network directly or through a gateway device, allowing them to communicate with one another and with cloud services and applications.
Create a layered architecture
An organization's IoT solution's architecture
outlines its overall layout, including its physical components (such as sensors and actuators) and virtual components (like services and communication protocols). IoT system complexity can be managed by utilizing a modular strategy that divides the architecture into several layers and focuses on each tier separately.
IoT architectures have a tendency to outsource work to the edges of IoT networks (where the physical devices connect to the cloud). This aids data-driven IoT applications
by lowering latency, enhancing privacy, and lowering bandwidth costs.
The device layer components include physical sensors and actuators that link to IoT devices and the IoT devices themselves. Although sensors and actuators are often not considered "smart" devices, they frequently connect to the architectural elements with higher computing power, either directly or indirectly (with the aid of gateway devices).
These devices often use over-the-wire protocols like Ethernet or wireless protocols like Bluetooth, Zigbee, WiFi, LTE, or RFID to transmit data.
The analytics and pre-processing services that are offered at the network's edge are included in the concept of the edge layer. This layer acts as a central integration point for subsequent layers (devices layer). For the upstream layers, it offers routing and device control features. In addition, this layer can be connected to pub-sub systems to convey events and listen in on them.
The size and heterogeneity of the devices and connectivity involved make designing data-driven IoT solutions hard. This article discusses some techniques for creating safe, adaptable, and scalable IoT architectures.
