Fog Computing and its Ecosystem In relation to "cloud computing", it is bringing the computing & services to the edge of the network. "Fog computing" is simply moving some of the computing power closer to the devices so that "the cloud" doesn't have to be consulted for every little minor detail. The group released a fog computing reference architecture in February 2017. It allows these actions to be spread more evenly across the network and not just on a central node. Fog computing is the answer to the constraints which restricted the use of Cloud Computing by various companies. Fog Computing Definition(s) Using a combination of local and cloud computing resources. Fog computing is a model to manage data, conducting near field communication with a sensor. The basic idea is to shift some of the computing from the data-centre to devices which are closer to the edge of the network – so moving the cloud to the ground (hence “fog computing”). Characteristics of fog computing are as follows [1]: a) Fog computing nodes are typically located away from the main cloud datacentres, at the edge. While the fog computing is been more favored by the service providers or the data processing companies, the edge computing is favored by the telecos and middle-ware companies that actually owns. Fog computing market to witness a robust CAGR of 65% over 2017-2024, healthcare applications to drive the industry trends. Edge computing, however, might or might not use fog computing. Cisco came up with the term “fog computing”. "One very exciting potential is Fog-as-a-Service - FaaS — where a fog service provider, which could be a municipality, telecom network operator, or webscale company, deploys a network of fog nodes to blanket a regional service area," he explains. Fog may seem intuitively obvious to some but it's extremely disruptive to traditional networking. Going from the cloud into the fog Also known as Edge computing or “Fogging,” Fog computing facilitates the operations of computing, storage, and networking services between end devices and cloud computing data centers. For more information about fog computing, visit the IEEE Xplore Digital Library. More recently, Chiang et al. Fog computing, their model suggests, is more efficient and more secure than a cloud computing approach to computing infrastructure for urban video surveillance. As a result, we can expect the initial confusion about ‘what the fog is?’. Defining characteristics of the Fog are: a) Low latency and location awareness; b) Wide-spread geographical distribution; c) Mobility; d) Very large number of nodes, e) Predominant role of wireless access,. ” The basic idea of fog computing is to leverage the key new software technologies, processes, and applications built to take advantage of cloud computing infrastructure, but deployed on computing hardware closer to the edge of the network. It reduces latency and required bandwidthB. Moreover, fog computing reduces the transfer of large data of video and audio recordings generated by video and dashboard cameras. The amount of network transmission and delay are notably reduced [35]. Whereas, in fog computing, the edge computing happenings are moved to processors linked to a local area network or into the hardware of LAN. Mist computing is defined as a "lightweight" or sub-fog layer that resides in the network fabric, with its nodes placed closer to edge devices. Mist computing is not a mandatory layer of fog computing and can work separately. Also known as Edge Computing or fogging, fog computing facilitates the operation of compute, storage, and networking services between end devices and cloud computing data centers. The application of Fog Computing in businesses has just started picking up the pace as the awareness about what it can do is increasing. Editor's note: The first part of this series discussed "Why fog computing is the killer app for the IoT. Therefore, the architecture of the network plays a key role in meeting the needs of the applications that operate over it. sensors, cameras, etc) and cloud data centers, to gather, store and process data instead of using a remote cloud data center (Figure One). Fog computing – Fog computing is a term created by Cisco that refers to extending cloud computing to the edge of an enterprise’s network. ” “Edge computing pushes the intelligence, processing power and communication capabilities of an edge gateway or appliance directly into devices like programmable automation controllers (PACs). Cloud computing is the process of using remote servers or computers across the internet to perform data operations, storage and managing data instead of using a local computer or server. Fog envisions open and standards-based horizontal architectures for distributing functions (from computing to storage to control and to networking functions) closer to users, not just to any. Fog computing is seen as an alternative to cloud computing that shifts some transactions and resources to the edge of a network, rather than establishing channels for cloud storage and utilization. The term fog computing is reaching this initial state of confusion now. But by the time the data makes its way to the cloud for analysis, the opportunity to act on it might be gone. Also, we observe the difference between cloud computing, fog computing, and edge computing. This redistribution enables an IoT gateway device with sufficient CPU cycles to decide, for example, whether to remotely enable or disable the building water supply in real time without first pushing sensor data to the cloud. Fog computing generates three tier architecture (clients fog cloud). It is then aggregated, normalized, and processed according to pre-defined rules, and acted upon. One study notes substantial challenges to privacy in fog computing as "fog nodes are in vicinity of end users and can collect more sensitive information than the remote cloud lying in the core network".
