Simply put, edge computing leads to fewer processes being run in the cloud. Instead, computing processes take place locally, thus reducing the need for long-distance data transfers to cloud servers, which can be expensive and slow. In traditional business applications, endpoints such as employees’ computers are used to collect or produce data. The data is then transmitted to an enterprise application using some combination of local area networks and wide area networks such as the internet. Once the data is processed, the output is transmitted back to the endpoint. However, edge computing can lead to large volumes of data being transferred directly to the cloud.
It also functions as a mediator that decides which information to process locally and which should be sent to the cloud. An IIoT environment in a manufacturing plant is an example of fog computing. Fog performs short-term edge analysis due to instant responsiveness, while the cloud aims for long-term deep analysis due to slower responsiveness.
This helps minimize processing time by removing the need for transferring data to a central processing system and back to the endpoint. As a result, data is processed more efficiently, and the need for internet bandwidth is reduced. This keeps operating costs low and enables the use of applications in remote locations that have unreliable connectivity. Security is also enhanced as the need for interaction with public cloud platforms and networks is minimized. Examples of edge devices are sensors, laptops, and smartphones. This article gives an overview of what Fog computing is, its uses and the comparison between Fog computing and Cloud computing.
On the other hand, cloud servers communicate only with IP, not with the endless other protocols used by IoT devices. The emergence of cloud computing is because of the evolution of IoT devices, and the cloud is not able to keep up with the pace. Fog computing allows for the distribution of critical core functions like storage, communication, computer, control, decision making, and application services closer to the origination of data. The new technology is likely to have the biggest impact on the development of IoT, embedded AI, and 5G solutions, as they, like never before, demand agility and seamless connections. By connecting your company to the Cloud, you can access the services mentioned above from any location and through various devices. Fogging provides users with various options to process their data on any physical device.
What Is Fog Computing?
This data can be used to improve efficiency, optimize operations and make better decisions. Gateway-level fog computingruns on devices that act as a gateway between the edge and the cloud. These devices can be used to manage traffic and ensure that only relevant data is sent to the cloud. Fog computing is an important trend to understand for anyone working in or planning to work in technology. It has many potential applications, from industrial and manufacturing settings to hospitals and other healthcare facilities. But what is fog computing, and how does it differ from cloud computing?
In cloud computing, end-users experience a quick response time with the help of dedicated data centers. While cloud computing takes more time to respond timely to each query, fog computing makes the process lot quicker. It is a distributed decentralized infrastructure that uses nodes over the network for deployment. Additionally, transmitting raw data to a remote cloud server using the internet may go against the regulations of certain jurisdictions. Fog computing addresses such concerns by ensuring a more private, secure, and compliant computing environment for processing sensitive information.

Fog can also include cloudlets — small-scale and rather powerful data centers located at the edge of the network. Their purpose is to support resource-intensive IoT apps that require low latency. Connecting your company to the cloud, you get access to the above-mentioned services from any location and via different devices. Moreover, there is no need to maintain local servers and worry about downtimes — the vendor supports everything for you, saving you money. Developers and businesses can use it to know their users better. Cloud services provide a safe environment where this data could be analyzed, managed, and stored.
Like edge computing, fog computers are not meant to replace cloud computing. Instead, ‘fogging’ complements the cloud by performing less intensive analytics and processing tasks at the edge. fog vs cloud computing This reduces the pressure on the cloud and allows it to focus on more long-term, resource-intensive tasks. Numerous fog computers process data in real time and create analytical summaries.
Naturally, edge computing is not a replacement for the cloud. In fact, these two technologies work with each other to add value through data. In edge networks, cloud computing is often dedicated to completing tasks that require more computing power, such as large-scale artificial intelligence and machine learning operations. By 2020, there will be 30 billion IoT devices worldwide, and in 2025, the number will exceed 75 billion connected things, according to Statista. All these devices will produce huge amounts of data that will have to be processed quickly and in a sustainable way.
What is the history of fog computing?
Fog brings the power of the cloud closer to the network edge and improves latency for mission-critical applications. Fog data is analyzed by a considerable number of nodes in the distribution system while in cloud computing, private information is transferred through channels that are connected globally. The fundamental issue being the latency and lesser security of data. Cloud computing is a centralized model of computer science, which makes the data and services available globally, making it a bit of a slow approach. High Security – because the data is processed by multiple nodes in a complex distributed system.
Fog computing has comparatively fewer data processing power. Besides letting people collaborate and communicate in real time, it also offers fast and easy access to data. Whether it is sending large files to your friends or working on the same file with your colleagues, flexibility, and convenience are impossible to imagine without cloud computing. Processing and StorageEdge ComputingFog ComputingIn the case of edge computing, data is processed and stored either within the edge computer itself or very close to it. A fog computer, by definition, is not capable of data collection or generation. As such, fog computing would not exist without edge computing.
What are the major differences between fog and cloud computing?
Traditional phones didn’t have enough built-in space to store the information and access various applications. Aspiring ethical hackers can get certified through EC-Council’s C|EH course. Connected health — supporting remote patient monitoring, telemedicine, and other healthcare applications.
Cloud platforms like AWS, Microsoft Azure, Google Cloud IoT service, and IBM IoT platform provide access to powerful cloud services able to handle the continuously growing volume of IoT data. Just like edge, fog is decentralized meaning that it consists of many nodes. Fog nodes are connected with each other and can redistribute computing and storage to better solve given tasks.
- IT infrastructure has evolved to bring computing resources to the point of data generation.
- Cars can transmit road condition data through fog computing to share directly with nearby drivers about potential hazards.

This can affect system capacity, efficiency, and security. Fog computing addresses this problem by inserting a processing layer between the edge and the cloud. This way, the ‘fog computer’ receives the data gathered at the edge and processes it before it reaches the cloud. I had no idea what fog computing was before reading this blog. I understood cloud computing, but fog was something I was not familiar with.
Edge computing: what is it?
Transmitting large volumes of data over long distances is not just a technical challenge. Many jurisdictions have implemented regulations that restrict the transfer and storage of data across national and regional boundaries. Such regulations dictate how organizations store, process, and use data and can impose debilitating penalties for non-compliance.
Difference between Fog Computing and Cloud Computing:
In this model, software and files are not stored on a local hard drive. Instead, a network of connected servers is used to store and answer different queries. The availability of services from any place, anytime, makes it a highly popular service in the fast-paced technology world. Fog computing brings the data storage and processing power closer to the user.
Cloud computing has a limitation of bandwidth while with fog computing, it resolves this problem by storing the data close to the ground. It doesn’t route through a centralized DC in the cloud; instead, it processes the data physically. Fog computing offers a better quality of services by processing the data of the devices that are even deployed in areas with high network density. It is a new distributed architecture, one that spans the continuum between the cloud and everything else. It makes fog computing, a common-sense architecture, and a necessary one for scenarios where latency, privacy, and other data-intensive issues are a cause for concern. When compared to fog computing, cloud computing has a significant latency.
