Information processing can reside anywhere in a network. Traditionally it has been in the data center and now the cloud. The Internet of Things (IoT) is forcing a reconsideration of centralized processing. When processing is performed at the network edge near the location of information production, it is called fog computing.
Is Fog Computing Right for Your IoT?
The Internet of Things (IoT) will involve millions to billions of endpoints in fixed and mobile situations. The processing of IoT data output can be accomplished in a data center or in the cloud.
