Abstract
Cloud computing with its three key facets (i.e.,
Infrastructure-as-a-Service, Platform-as-a-Service, and Softwareas-
a-Service) and its inherent advantages (e.g., elasticity and
scalability) still faces several challenges. The distance between
the cloud and the end devices might be an issue for latencysensitive
applications such as disaster management and content
delivery applications. Service level agreements (SLAs) may also
impose processing at locations where the cloud provider does not
have data centers. Fog computing is a novel paradigm to address
such issues. It enables provisioning resources and services outside
the cloud, at the edge of the network, closer to end devices, or
eventually, at locations stipulated by SLAs. Fog computing is not
a substitute for cloud computing but a powerful complement. It
enables processing at the edge while still offering the possibility
to interact with the cloud. This paper presents a comprehensive
survey on fog computing. It critically reviews the state of
the art in the light of a concise set of evaluation criteria. We
cover both the architectures and the algorithms that make fog
systems. Challenges and research directions are also introduced.
In addition, the lessons learned are reviewed and the prospects
are discussed in terms of the key role fog is likely to play in
emerging technologies such as tactile Internet.
