Edge computing, also known as fog architecture, is a distributed computing paradigm that allows processing, storage, and communication to take place at the network's edge rather than in a centralized cloud environment. This means that rather than sending data to a remote data center for processing, the processing is done locally on devices closer to the source of the data.
Fog architecture can provide several benefits in the context of IoT
Because data is processed locally, the time it takes for data to travel from the device to the cloud and back is reduced, resulting in lower latency.
With fog architecture, devices can continue to operate even if connectivity to the cloud is lost. This is due to the network's distributed processing and storage capabilities.
By distributing processing and storage capabilities across the network, fog architecture can help reduce the load on the cloud. As a result, the network's scalability improves because it can handle more devices and data.
By allowing data to be processed locally rather than sending it to the cloud, fog architecture can provide enhanced security. This reduces the possibility of data breaches while also ensuring that sensitive data remains on the device.
Broadly speaking, fog architecture has the potential to significantly benefit IoT by allowing devices to process and analyze data locally while still having access to cloud-based services when necessary.
