Fogxy

Abstract

Fog computing is an emergent approach that tries to overcome challenges the cloud faces by introducing a fog tier in between the cloud and the edge of the network. With the advent of the cloud, computing power shifted back again to centralized locations. In past decades, we have seen an alternation between centralization and decentralization. Although the cloud is highly scalable and performant, it exhibits limitations such as real-time capabilities. Fog computing is an approach that tries to overcome these shortcomings. The implementation guidelines for fog computing system are vague to be implemented in real-world applications. Smart objects at the edge benefit from low latency responses, location awareness, and higher availability provided by fog computing. In this paper, we present Fogxy, an architectural pattern for fog computing. It serves as an implementation guidance that describes a solution to a recurring problem in a given context. Fogxy is composed of different patterns and is based on the idea of the proxy pattern. Fogxy gives an overview of the implementation of fog computing applications and takes into account the integration of cloud computing and Internet of Things (IoT) technologies.
