What is Fog Computing? Definition and FAQs

Cloud computing forms a comprehensive platform that helps businesses with the power to process important data and generate insights. Fog computing is like the express highway that supplies computing power to IoT devices which are not capable of doing it on their own. Fog computing encapsulates edge processing as well as the network connections required to bring that data from the edge to its endpoint.

Services are hosted at the network edge or even end devices such as set-top-boxes or access points. By doing so, Fog reduces service latency, and improves QoS, resulting in superior user-experience. Fog Computing supports emerging Internet of Everything applications that demand real-time/predictable latency . Thanks to its wide geographical distribution the Fog paradigm is well positioned for real time big data and real time analytics. Fog supports densely distributed data collection points, hence adding a fourth axis to the often mentioned Big Data dimensions .

A very machine way of network management

Fog nodes can detect anomalies in crowd patterns and automatically alert authorities if they notice violence in the footage. According to Domo’s ninth annual ‘Data Never Sleeps’ infographic, 65% of the world’s population — around 5.17 billion people — had access to the internet in 2021. The amount of data consumed globally was 79 zettabytes, and this is projected to grow to over 180 zettabytes by 2025. The rapid growth of wireless technology has given https://www.globalcloudteam.com/ mobile device users tremendous computing power. Another use case for fog computing is for IoT applications, such as the next generation smarter transportation network, known as V2V in the US, and the Car-To-Car Consortium in Europe. By adding the capability to process data closer to where it is created, fog computing seeks to create a network with lower latency, and with less data to upload, it increases the efficiency at which it can be processed.

Cloud computing can be applied to e-commerce software, word processing, online file storage, web applications, creating image albums, various applications, etc. In fog computing, data is received from IoT devices using any protocol. Fog computing is defined by its decentralization of computing resources and locating these resources closer to data-producing sources. This revenue stream creates value for IoT fostering highly functioning internal business services. Fog computing also provides a common framework for seamless collaboration and communication helping OT and IT teams to work together to bring cloud capabilities closer. Even though modern devices are improving, fog computing stills needs more efficient and powerful devices to tackle its requirements.

What Is Fog Computing?

Though cloud servers have the power to do this, they are often too far away to process the data and respond in a timely manner. The servers themselves would get overloaded and it would be a big problem. So instead of having cloud servers do all the processing, why don’t we have all of those edge devices handle their computing needs and only send the results back to the server? Traditional cloud computing architectures do not meet all of those needs. The prevailing traditional cloud computing approach of moving all data from the network edge to the data center or cloud for processing adds latency. The network bandwidth capacity is incapable of coping with the volume of traffic from thousands of these devices.

In contrast, Fog computing aims to improve efficiency and reduce the transformation of data or data operations from and to remote networks distributed across different locations. Fog computing is also vulnerable to cyberattacks since most of the devices connecting to the fog node are not authenticated. Large organizations utilize multiple devices, and it is a nearly impossible task to authenticate all of them. Plus, restricting access to the fog nodes detracts from the whole purpose of fog computing. Encryption can help mitigate this vulnerability, and user behavior profiling using Machine Learning can help you find irregularities in user behavior that could signal an attack.

Overcoming Zero Trust Challenges with Edge Computing

We can consider Fog computing whenever extreme edges such as railways, ships, vehicles, and roadways collect a large amount of data. Cloud computing architecture systems can be divided into two sections, a front end, and a back end, in which both will be connected as a network. In contrast, Fog computing extends cloud computing by providing features at the network’s edge.

These client PCs had more intelligence than their mainframe counterparts, but a lot of the processing power did reside with the server itself. Incidentally, during the PC client-server era, the Internet gained worldwide popularity and forever transformed every aspect of how we connect and work. It necessitates the fast transfer of data between IoT devices and nodes. Of course, different connectivity choices are available depending on the scenario. A connected factory floor sensor, for example, may require a wired connection. On the other hand, a mobile resource, such as an autonomous car or a wind turbine in the middle of a field, will necessitate another kind of connection.

Power-efficiency – Edge nodes run power-efficient protocols such as Bluetooth, Zigbee, or Z-Wave.

  • Data is not the issue; we have more of it than we can analyze or utilize already, and we’re gathering more and more every day.
  • It seems prudent then to consider how we might bring at least some of our data back down to earth until the US and other western nations have the wired and wireless Internet speeds we deserve.
  • It’s a decentralized computing platform in which data, computation, storage, and applications are stored somewhere between the data source and the cloud.
  • So, Cloud computing, as one of the main enablers of the IoT that offers centralized services, cannot solely satisfy the requirements of IoT applications.

Because the initial data processing occurs near the data, latency is reduced, and overall responsiveness is improved. The goal is to provide millisecond-level responsiveness, enabling data to be processed in near-real time. However, any device that has storage, computing, and network connectivity can also act as a fog node. When there’s a large and distributed network, these nodes are placed in various key areas to allow for essential information to be analyzed and accessed locally. Dealing with data privacy, data encryption and decryption, and data integrity, this layer makes sure that privacy is secure and preserved for data that is outsourced to the fog nodes. When it comes to fog computing, privacy can be data-based, use-based, and location-based.

Advantages of Fog Computing

Fog computing is especially important to devices connected to the internet of things . Each “smart device” is equipped with its own micro-controller, enabling basic data processing and communication with other IoT devices and sensors. fog computing vs cloud computing The marketing term “fog computing” originates from the technology company Cisco, one of the leading manufacturers of network solutions. The expression is actually a clever metaphor that refers to the difference between fog and clouds.
