In a smart city infrastructure, edge computing is utilized to process data from various IoT devices, such as traffic cameras and environmental sensors. A city planner is evaluating the performance of two edge computing solutions: Solution X processes data locally at the edge with a latency of 20 milliseconds, while Solution Y sends data to a centralized cloud server, resulting in a latency of 100 milliseconds. If the city experiences a peak traffic load where 500 devices are generating data every second, calculate the total latency for processing data from all devices using both solutions over a period of 10 seconds. Which solution would provide a more efficient data processing strategy for real-time applications in this scenario?
