I believe most people are familiar with edge computing and cloud computing. They seem to be the same, but in fact, there are big differences. So this article will help you understand the difference between edge computing and cloud computing. First of all, we need to understand the concept, so let’s first understand the concept of edge computing.
The concept of edge computing: Edge computing is an open platform that integrates core capabilities such as connection, computing, storage, control, and application at edge nodes close to terminal devices or data sources to meet users’ real-time, intelligence, data aggregation, and security needs. The collected data is calculated and processed in the local gateway, and then uploaded to the cloud server.
Cloud computing concept: Cloud computing here needs to be understood in this way, which is to collect sensor data from the terminal, transmit it to the cloud server, and then calculate and process it through the cloud server, and present and display the data in front of the user.
Let’s use an example to illustrate. When a person accidentally touches a fire, he will subconsciously retract his hand, and then he will feel some pain when he touches the fire. This action of retracting his hand is caused by the central nervous system of the spinal cord. out response. The feeling of pain when touching fire is the response of the brain. If there is no central nervous system in the spinal cord to respond first to the brain. Then we will feel the pain first, and then retract our hand. At this time, the hand may be burnt. So here, we compare edge computing to the central nervous system of the spinal cord, and cloud computing to the brain.
In the past, data from terminal devices had to be transmitted to the server for processing through the gateway. With edge computing, the local gateway provides computing power, data storage, and some warning responses. Reduce latency and improves reliability. The above is about the difference between edge computing and cloud computing. Hope it helps you!
Resuma
Cloud computing transfers the data collected by the terminal to the cloud server for processing. Edge computing transfers the data collected by the terminal to the local dispositivo de puerta de enlace for direct processing, and then uploads it to the cloud.
Extensions
The concept of edge computing has been introduced above. In industrial applications, edge computing is not only about data transmission but also about local processing and real-time control.
For example, IOTRouter’s EM300 Modular Industrial Edge Controller combines data acquisition, protocol conversion, and edge control in one device. With 4× isolated RS485, DI/DO interfaces, Ethernet, and optional wireless connectivity, EM300 can connect with PLCs, CNC machines, sensors, and meters.
Supporting protocols such as Modbus, BACnet, IEC104, MQTT, and HTTP, EM300 enables local logic execution, automatic data collection, and cloud connectivity. By processing critical data at the edge before uploading, it improves response speed, reduces cloud workload, and helps upgrade traditional industrial systems into Industrial IoT solutions.
