World is developing at a quick pace as is data. The boom of smart phones and Internet of Things (IoT) enable more
users to access data as well as computation power in real-time. The constraints of current distributed computing is a subject of
more prevalent concern. In response to these rising difficulties in computing, as new requirements and challenges spring up day
by day, especially in cloud computing scenario, computing paradigms that can meet these challenges are sought after. In order
to expand the efficiency and to decrease the quantity of the data to be sent to the cloud for processing, numerous solutions have
been proposed for the edge-centric network. In this paper, an elaborate study of computing architectures proposed for edge
paradigms is carried out and application areas in the Internet of Things are ascertained
