In today's world, the Internet of Things i.e IoT has possessed a great impact in our life. Almost everything from electrical to electronic gadgets have become a part of IoT due to which the data production and consumption have increased. Cloud computing due to its centralized architecture is not enough to handle this exponential growth of data it suffers from and thus certain limitations. Due to the drawbacks of cloud computing, a decentralized computing paradigm called fog computing was coined where computation of data used to happen near to the network edge. But due to some limitations of fog computing a similar type but an advancement over fog came into existence called edge computing which could resolve all the major drawbacks and challenges of cloud and fog to a large extent. Certain issues regarding high latency, high response time, high bandwidth cost, high energy consumption and high security threat are now resolved by edge computing to a large extent with lots of popular emerging fields and applications running on this concept. So the overall journey of this paper focuses on what exactly edge computing is and the need of edge computing in this growing world of data and how edge computing introduces the technology world with some of the emerging applications being widely used nowadays.
