This second issue of 2017, centers on connecting fog and cloud computing. The columns and articles in this issue are focused on fog, edge and cloud computing. Fog computing was introduced sometime in 2014. Edge computing and fog computing try to achieve the same goal, but through different approaches. Fog computing moves intelligence to the IoT gateways or to the local area network. Meanwhile, edge computing pushes intelligence to the edge devices- at the bottom of the architecture hierarchy.
