Fog computing (FC) is an budding computing
platform pursuits at bringing computation
approximately to its facts resources, which may
additionally reduce the latency and cost of delivering
statistics to a far away cloud. These characteristic and
related advantages are applicable for plenty Internet-of-
Things programs, especially latency sensitive and task in
depth services. With comparisons to other computing
technologies, the definition and architecture of FC are
offered in this paper.
The framework of useful resource allocation for
latency discount combined with reliability, fault
tolerance, privateness, and underlying optimization
issues also are mentioned. The resulting analysis
generates a few vital insights on the scalability of the FC
