Edge computing: A technological advancement in Internet of Things and cloud computing.

Internet of Things (IoT) is emerging technologies these days which generates high volume of data. Efficient use of data analytics techniques on discrete data using Cloud Computing provides significant and precise information. In view of the traditional applications, an IoT application such as environmental monitoring, smart navigation and smart healthcare comes with separate requirements such as mobility, quick and real-time response etc. However, the typical cloud computing architecture cannot satisfy and fulfil these requirements due to processing of the data being distributed across the world remotely from physical location of installed IoT devices. Hence, the concept of edge computing emerged to perform data storage and processing at the extreme end of the networks, which is closer to data collection sources than the cloud storage. This makes applications computationally efficient and location-aware. But edge computing brings many security and privacy challenges when applied to data analytics in association with IoT devices.
