{"id":"edge-computing","model_id":"NIST SP 500-325","name":"NIST SP 500-325 Fog Computing Conceptual Model","summary":"NIST Special Publication 500-325 is a conceptual model document that defines fog computing and mist computing and describes how they relate to cloud-based computing models for the Internet of Things. It characterizes properties of fog computing, including service models and deployment strategies, as a baseline for what fog computing is and how it may be used. The model addresses limits of traditional cloud-based IoT systems, such as large scale, heterogeneity and high latency, by decentralizing applications, management and data analytics into the network itself.","study_notes":["Fog computing is described as a distributed and federated computer model that decentralizes applications, management and data analytics into the network itself.","The document presents definitions of both fog computing and mist computing.","Fog and mist computing are presented in relation to cloud-based computing models for IoT.","Traditional cloud-based IoT systems are described as challenged by large scale, heterogeneity and high latency in some cloud ecosystems.","The document characterizes fog computing properties including service models and deployment strategies.","Keywords listed include cloud computing, cloudlet, edge computing, fluid computing, fog computing, Internet of Things (IoT) and mist computing.","Published as NIST Special Publication (NIST SP) 500-325, report number 500-325, in 2018.","Authors listed: Michaela Iorga, Larry Feldman, Robert Barton, Michael J.
