The concept of the Internet of Things (IoT) is a reality now.

However, enabling learning from distributed data over such edge Internet of Things (IoT) systems (e. g., mobile-health and wearable technologies, involving sensitive personal/medical data) in a privacy-preserving fashion presents a major challenge mainly due to their stringent resource constraints, i. e., limited computing capacity, communication bandwidth, memory storage, and battery lifetime.
The emerging trend of edge computing has led several cloud providers to release their own platforms for performing computation at the 'edge' of the network.
