Fog computing, also known as fog networking, is a decentralized computing infrastructure that is likely to emerge as next generation cloud computing. In fog computing, computing and storage of data are distributed in the most logical and efficient manner between the data source and the cloud. This is because the Internet of Things (IoT), a technology closely associated with cloud, is creating enormous volumes of data, but by the time it finds its way to the cloud for analysis, it is often late to act upon it. Fog computing helps to do away with this drawback by analyzing the most time sensitive data at the network edge, close to its generation source, instead of sending large volumes of data to the cloud for historical analysis and storage.
The two main components in the fog computing market are hardware, comprised of servers, routers, switches, gateways, and controller, and software comprised of customized application software and fog computing platform. Of the two, the software segment generates maximum revenue because of the low capital requirement. Fog computing is finding application in building and home automation, smart energy, connected health, smart manufacturing, transportation and logistics, security and emergencies systems among others.
Geographically, North America currently leads the global fog computing market and going forward too, is slated to maintain its leading position on the back of substantial investments made in the region to develop this technology. High penetration rate of the fog computing technology is primarily responsible for the growth in market of North America.

Fog computing is a computing technology which decentralizes application and computing resources in the most efficient and effective point. Fog computing technology is also known as fog networking. Fog computing enhances efficiency and helps in reducing the size of the data which would be uploaded to the cloud for the purpose of analysis, data processing and storage. Fog computing also helps in enhancing compliance and security for the end users. In fog computing atmosphere, most of the data processing is done over smart mobile devices and data hubs. Moreover, other devices like gateway and smart router are also used in fog computing. Due to this distributed approach fog computing is gaining popularity. The demand for fog computing is driven by the requirement for managing enormous amount of data which is generated by the sensors. Further fog computing enable portability, the fog enables the cloud to be more conveniently positioned to act and produce on Internet of things (IoT) data.
