Fog computing

Fog computing is an architecture that uses edge devices to carry out a substantial amount of computation (edge computing), storage, and communication locally and routed over the Internet backbone

Fog computing is intended for distributed computing where numerous “peripheral” devices connect to a cloud.

The word “fog” refers to its cloud-like properties, but closer to the “ground”, i.e. IoT devices1

Fog computing can be used for applications where real-time processing of data is required, such as Internet of things (IoT), game streaming, augmented reality, etc. 

Fog computing may also provide security and privacy benefits by performing cryptographic computations locally instead of remotely
