fog computing

Fog computing or fogging computing works like cloud computing or edge computing with a decentralized infrastructure. Fog computers are functionally comparable to edge servers, which operate at the edge of the Internet, take over tasks for the network and the application, and thus reduce data traffic to and from the cloud.

In fog computing, applications and services are stored directly at the edge of the network, making them directly available to applications. In addition, unlike edge servers, Fog computers can also perform real-time virtualization across multiple systems. Real-time performance is one of the most important criteria of Fog computing.

The difference between Fog computing and cloud computing can be seen in the location where the services are provided. Fog computing is performed at the edge of the network near the application, whereas cloud computing is performed in data centers at the network center. The servers for Fog computing are located in close proximity to the end users, which results in lower quality of service latency. The strategic location for Fog computing improves efficiency and reduces the amount of data that must be transported across the network to the cloud, where it is processed, analyzed, and stored.

Fog computing is used in the Internet of Things( IoT) and the Internet of Everything( IoE), where devices are connected to many other devices and components and where they perform control and management functions for applications.
