Provided is an edge-based load shedding system. The edge-based load shedding system includes an analysis server configured to determine to perform server or edge separation execution, transmit an operational module of an analysis application, issue a request to offload the transmitted operational module, and receive and analyze data obtained through preprocessing and an edge machine configured to receive and offload the operational module from the analysis server, preprocess raw data collected from a sensor by using the offloaded operational module, and transmit the data obtained through the preprocessing to the analysis server.
