An exemplary system includes a cloud server configured to provide a service to a client device by way of a network. The cloud server implements a batch layer of a data-processing architecture. The system further includes an edge computing device configured to provide a latency-sensitive task of the service to the client device by way of the network in response to a request from the client device to offload the latency-sensitive task. The edge computing device is separate from and communicatively coupled to the cloud server, is located at an edge of the network such that a latency of data communications between the edge computing device and the client device is lower than a latency of data communications between the cloud server and the client device, and implements a speed layer of the data-processing architecture at the edge of the network.
