Fog Computing Defined
4 likes2,039 views
The document, crafted by Angelo Corsaro, discusses fog computing and its necessity in the context of the growing number of IoT devices, which are often incompatible with cloud-centric architectures. It defines fog computing as a system-level architecture that brings computing closer to users to enhance performance and reduce latency, particularly for industrial applications. Additionally, it compares fog computing with mobile edge computing (MEC) and highlights the importance of developing infrastructure that can effectively handle the demands of the Internet of Things.
