IoT Edge refers to the edge of a network where IoT devices and sensors collect, process, and transmit data. The edge is the first place where data from any IoT device is processed, before it is sent to the cloud (see the importance of IoT) for further analysis and storage.
To put it in simple terms, the edge can be thought of as a network of IoT products that are capable of doing certain tasks and decisions locally, without intervention of the cloud.
Security of IoT edge devices
IoT edge devices move data processing from cloud servers to the edge of a network. This helps reduce the amount of sensitive data transmitted and processed centrally, lowering the risk of data leaks.
It also spreads data processing over multiple devices at the edge, improving reliability but making security more difficult. To address security concerns, IoT gateways and security solutions provide security directly to devices at the edge, improving overall security.
Advantages of using IoT Edge
One of the main benefits of the IoT edge is that it allows companies and users for faster decision making and reduced latency, as well as reducing the amount of data that needs to be transmitted to the cloud, which can improve overall network efficiency and reliability.
Another advantage of the IoT edge is that it allows for more secure and privacy-sensitive data processing. When an IoT device processes the data locally, that is, at the edge, sensitive information can be kept out of the cloud (see IoT clouds), and this reduces the risk of data breaches and privacy violations.
Cost savings. Among the advantages of using IoT edge devices, we find out these technologies are ideal for saving costs. This is very useful for the deployment and maintenance of several IoT devices around specific areas.
Improved efficiency and reliability. If a company is using IoT devices to process data at the edge, they can improve the efficiency of the network by reducing the amount of data that needs to be transferred over it. By doing so, the response times of the IoT technology is faster than if needed to transmit first the data to a cloud.
An example of IoT edge could be IoT sensors, which usually run on low-power microprocessors, and are designed to be low-cost, and low-power. These sensors can be installed almost anywhere, and they can gather information from their environment without problems.
What is the goal of IoT edge devices?
We could say the goal of IoT edge devices is to provide an architecture that is decentralized, and that ensures the local collection, processing, and analysis of data generated by IoT devices and sensors.
