Difference between Fog Computing and Edge Computing

Difference between Fog Computing and Edge Computing

Both fog computing and edge computing are relatively new concepts in the world of technology. Fog computing is a type of distributed cloud computing that moves the logic and processing of data closer to the sources that produce or consume it. Edge computing, on the other hand, refers to the practice of bringing computation and storage resources as close to users as possible. We will explore the key differences between fog and edge computing. We will also discuss some of their respective benefits and use cases.

What is Fog Computing?

  • Fog computing is a term for data processing that takes place at or near the edge of a network, rather than in a centralized data center. In a fog computing environment, data is gathered and processed by devices such as sensors, routers, and gateways that are located close to the point where it is generated.
  • This type of distributed computing can reduce latency and improve reliability since data does not have to travel as far to be processed. Fog computing is often used in applications such as industrial automation, smart cities, and the Internet of Things (IoT), where real-time data processing is required.
  • While fog computing can offer many advantages, it can also create new security risks, since data is more vulnerable to attack when it is spread across a larger number of devices.

What is Edge Computing?

  • Edge computing is a distributed computing model in which data is processed at the edge of the network, close to the source of the data. This is in contrast to the traditional centralized model in which data is processed in a central location. Edge computing can be used to reduce latency, improve scalability, and increase security.
  • In many cases, edge computing is used in conjunction with cloud computing to provide a hybrid solution. For example, data from connected devices may be processed at the edge of the network to reduce latency and improve responsiveness.
  • The results of the processing may then be sent to the cloud for storage and further analysis. Edge computing can also be used to improve security by processing sensitive data locally and keeping it within the control of the organization. This reduces the risk of data breaches and helps to safeguard sensitive information.

Difference between Fog Computing and Edge Computing

  • Fog computing and edge computing are two approaches to managing data processing and storage in distributed systems. Both fog and edge computing bring data processing and storage closer to the source of information, reducing latency and improving performance.
  • However, there are some key differences between the two concepts. Fog computing is designed to support real-time applications that require low latency, such as video streaming and voice-over IP.
  • Edge computing, on the other hand, is geared towards more general-purpose applications that can tolerate slightly higher latency. In addition, fog computing often relies on proprietary hardware and software, while edge computing can be implemented using standard off-the-shelf components.

Finally, fog computing is typically deployed in a limited geographical area, such as a single building or campus, while edge computing can be deployed across a wide area, such as a city or region.


Edge Computing is a term for data processing and content delivery that takes place at the edge of the network, as close to the user as possible. Edge Computing moves some or all computing functions away from centralized servers and clouds to locations closer to where the data is created or consumed. This can improve performance and reduce latency because the traffic doesn’t have so far to travel.

It can also save money by reducing bandwidth requirements and eliminating the need for expensive networking infrastructure between users and central servers. Fog Computing extends Edge Computing by adding an intermediary layer of fog nodes between end devices and cloud services.
