Moving from cloud to fog: scenarios and security concerns

Abstract

ARTICLE INFO ABSTRACTWith the increasing needs of on demand availability of data and ubiquitous access to shared pools of system resources cloud computing has emerged as a successful paradigm to meet dynamic user demands. In addition to this the rise in usage of mobile devices, Internet of Things has gained popularity due to its huge potential to connect physical devices to the internet and thus enabling each device to share data with the surrounding devices and virtualized technologies in real time environment. Consequently skyrocketing data access needs require a new paradigm that can provide wide spread geographical distribution, location awareness and low latency. As a result Fog Computing has been recently introduced to provide real time analytics in heterogeneous environments. This paper gives a close look on FC paradigm and investigates its applications in real life. We discuss security and privacy issues in FC and state of the art of Fog Computing.
