A study of fog computing technology serving internet of things (IOT)

The Internet of Things (IoT) is producing a massive amount and diversity of data that has never been seen before. However, by the time the data reaches the cloud for processing, the chance to act on it may have passed. This white paper describes a new paradigm for evaluating and acting on IoT data for IT and operational technology experts. Edge computing or fog computing are two terms for the same thing. Instead of transmitting huge quantities of IoT data to the cloud, analyzes the most time-sensitive data at the network edge, near to where it is produced; acts on IoT data in milliseconds, depending on rules; Sends chosen data to the cloud for longer-term storage and historical analysis. In certain IoT applications, it's critical to speed up data processing in order to obtain real-time results. CISCO developed fog computing, a next-generation networking technology, to achieve this goal. It's similar to the cloud, but smaller, and it serves the network's edge from a closer geographical location. It has the potential to increase the yields of ubiquitous smart networks and is a step toward a smarter world. The goal of this article is to explain the fundamental idea of fog computing technology and compare it to other comparable technologies. The difficulties of this technology are addressed, as well as current work done to solve them.
