What Is Fog Computing? NIST Publication Presents This Complex Model That Supports Internet of Things Devices
NIST is releasing Special Publication 500-325, Fog Computing Conceptual Model, which presents the conceptual models of fog and mist computing and how they relate to cloud-based computing models for the Internet of Things (IoT). Until recently, much of the data from IoT devices has been managed and stored through cloud computing, a centralized network of computers and servers connected together over the Internet. But access to data through the cloud can be slow at times, because the data needs to be transported to the cloud for processing, analysis and storage. An alternative to cloud computing is fog computing, a decentralized infrastructure in which data is accessed locally, which significantly reduces the amount of time it takes to access the data. The publication presents the conceptual model of fog computing and an alternative model called mist computing and how they relate to cloud-based computing models for IoT. The document also characterizes important properties and aspects of fog computing, including service models and deployment strategies, and provides a baseline of what fog computing is and how it may be used.
