Fog computing: An emerging paradigm

Fog computing also termed as edge cloud is an emerging paradigm. It adds another layer between edge devices and the Cloud Core. Besides the functionalities of compute, storage, and networking, it caters the need of low latency and real-time interactive applications, which Cloud Computing lacks. It offers limited analytic services due to constraints and capabilities of connected devices. However it can communicate with core cloud for services requiring extensive computing resources. This paper discusses the key characteristics of Fog computing, looks into ongoing research of this paradigm, and highlights the challenges and issues in the development of its architecture.
