1. Basic concepts and technical principles of edge computing
Edge computing, also known as distributed computing, is a computing method that pushes computing tasks from the cloud to the edge of the network. In edge computing, devices or terminals near the data source have computing power, and some or all computing tasks can be processed locally without transferring data to the cloud. This computing mode has the advantages of low latency, high bandwidth, and high privacy protection, and provides a better solution for many real-time applications.
The main technical principle of edge computing is to decompose computing tasks into multiple sub-tasks and assign these sub-tasks to each edge node for distributed computing. Edge nodes can be peer nodes, or devices with strong computing capabilities such as gateways and servers. Through this distributed computing method, edge computing can improve computing efficiency and response speed, while reducing the data processing burden on the cloud.
