Fog Computing is a paradigm where cloud computing is extended to the edge of the network. This creates a highly virtualized platform that provides compute, storage, and networking services between end devices and traditional cloud computing data centers.

These services are the building blocks of both the cloud and the fog. They're also critical for supporting the emerging wave of Internet deployments—most notably the Internet of Everything (IoE). Internet deployments require mobility support and geo-distribution, location awareness, real-time interactions, and low latency. Also important is the ability to support a very large number of nodes in highly heterogeneous environments.
