Background
Compared with cloud computing, which is to intensively deploy software and hardware resources in a large data center far away from users, edge computing is to place computing resources closer to the "edge" of users or devices, thereby reducing delay and bandwidth consumption and providing real-time processing near data sources.
Edge computing moves portions of the storage and computing resources out of the central data center and closer to the data sources themselves. So that the raw data can be partially processed and analyzed where it is actually generated without having to be transmitted to a central data center. Only the results that have been processed by the edge computation will be sent back to the main data center.
The definition of "branch" has now exceeded the traditionally understood branch consisting of four-sided walls. The internet of things (IoT) and mobility are redefining the concept of branches, which may even be the agricultural domain of machines and devices with interactions. This new model increases the demand for edge services so that edges can go deeper into branches and cross local area network boundaries to support internet of things device traffic.
