Low latency – Fog tends to be closer to users and can provide a quicker response. Unfortunately, nothing is spotless, and cloud technology has some drawbacks, especially for Internet of Things services. PaaS – A development platform with tools and components to build, test, and launch applications. Fog computing uses different protocols and standards, so the risk of failure is very low. Fog does short-term edge analysis due to the immediate response, while Cloud aims for a deeper, longer-term analysis due to a slower response. On the other hand, Cloud servers communicate only with IP and not with the endless other protocols used by IoT devices.

Cloud Computing Vs Fog Computing

In this post, we went through the definitions and characteristics of main computing and storage approaches — cloud, fog and edge computing. We described how each of them works with data and made a quick cloud computing vs. fog computing vs. edge computing comparison to show where each approach works best. Fog is an intermediary between computing hardware and a remote server.

High security — because data is processed by a huge number of nodes in a complex distributed system. Fog computing allows us to locate data over each node on local resources and thus making the analysis of data more accessible. However, fog computing is a more viable option in terms of managing a high degree of security patches and reducing bandwidth issues. Cloud computing can be applied to e-commerce software, word processing application, online file storage, web application, creating image albums, diverse applications, etc. The fog has a decentralized architecture where information is located over different nodes at the user’s closest source. The back end is the system cloud section which is responsible for securing and storing data.

Fog Computing vs Cloud Computing

The cloud architecture is centralized and consists of large data centers located around the world over a thousand miles away from client devices. Although these tools are resource-constrained compared to cloud servers, the geological spread and decentralized nature help provide reliable services with coverage over a wide area. Fog is the physical location of computing devices much closer to users than cloud servers. The integration of the Internet of Things with the cloud is a cost-effective way to do business.

The Architecture That Brings The Cloud To The Edge

Fog computing builds a bridge between local drives and third-party cloud services, allowing a smooth transition to fully decentralized data storage. These computing technologies differ in their design and purpose but often complement each other. Let’s take a look at the key benefits of cloud, fog and edge computing to better understand where to use each of these approaches.

Mobility – Fog computing supports the mobility of IoT devices to a certain extent. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. It lags in providing resources where there is an extensive network involved.

One of the approaches that can satisfy the demands of an ever-increasing number of connected devices is fog computing. It utilizes the local rather than remote computer resources, making the performance more efficient and powerful and reducing bandwidth issues. IaaS — a remote data center with resources such as data storage capacity, processing power and networking. The term fog computing was created by Cisco—but originally it had nothing to do with the IoT. A decade or so ago, hybrid cloud architectures combining existing on-premises computing power with public cloud resources were increasingly popular. Cisco presented fog computing as a way of reducing latency between local and remote computing resources, but had trouble getting uptake in the market.


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. In simple terms, fog computing is cloud computing plus the Internet of Things. But still, there is a difference between cloud and fog computing on certain parameters. Devices at the fog layer typically perform networking-related operations such as routers, gateways, bridges, and hubs. The researchers envision these devices to perform both computational and networking tasks simultaneously. The solution is to move some computing power to the edges of the system, something known as fog computing.

Fog Computing vs Cloud Computing

It can store more data storage than fog computing with limited processing. When smart devices generate data, everything is piled on and transferred to the cloud for further processing. When this happens, the cloud’s data centers and networks are overloaded.

Pros Of Cloud For Iot

Log analysis and wireless management are common AI use cases in networking. Fog Computing shifts the edge computing tasks connected to the LAN hardware or for LAN direct to be more distant to the sensors. The reason being that cloud is at a distance from the point of origin whereas, in fog computing, it analyzes and reacts to the data in less than a second. 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. By connecting your company to the Cloud, you can access the services mentioned above from any location and through various devices.

Fog Computing vs Cloud Computing

Will be interesting to see how the advancements in 5G technology will impact fog computing. Because as 5G continues to roll out, more and more devices will have the power and speed levels to become interconnected. A more complicated system — fog is an additional layer in the data processing and storage system.

The CEO of the data streaming vendor discusses the direction Hazelcast is heading in as it launches a serverless platform for … Data privacy concerns stemming from data collection practices of social media platforms means corporate leadership should be … is an ambitious publication dedicated to the evolving landscape of marketing and technology in business and in life. Another use case is the application on smart grids along with usage in real-time analytics. Rather than saving data to the nearby hard drive on a solitary PC, clients store it on outsider online workers. Portability – The IoT devices can be moved around in the general area covered by ‘edge’.

It controls what information should be sent to the server and can be processed locally. In this way, Fog is an intelligent gateway that dispels the clouds, enabling more efficient data storage, processing, and analysis. IaaS – A remote data center with data storage capacity, processing power, and networking resources.

WINSYSTEMS’ expertise in industrial embedded computer systems can leverage the power of the IIoT to enable the successful design of high-performing industrial applications. This article gives an overview of what Fog computing is, it’s uses and the comparison between Fog computing and Cloud computing. Cloud is performing well in today’s World and boosting the ability to use the internet more than ever. Cloud computing gradually developed a method to use the benefits of it in most of the organizations. Fog computing can be apparent both in big data structures and large cloud systems, making reference to the growing complications in retrieving the data accurately.

For example, facial recognition in a security system requires AI; a camera system in the field would therefore need fog nodes to do the heavy lifting. IoT is a new frontier when it comes to infrastructure, and it’s not always as simple as edge vs. cloud computing. Organizations must determine whether edge or cloud computing will best distribute processing resources for optimal performance and then weigh the challenges. In the case of this technology, computing happens at the edge of a device’s network. This essentially means that the computer is connected to the network located in the device.

Difference Between Fog Computing And Cloud Computing:

Developers can leverage IoT cloud platforms and benefit from third-party computing power, data management services, inbuilt security, etc. The decentralized data storage approaches correspond with some of the main IoT needs, such as accessibility, safety, mobility, and real-time processing. Cloud is the centralized storage situated further from the endpoints than fog vs cloud computing any other type of storage. This explains the highest latency, bandwidth cost, and network requirements. On the other hand, cloud is a powerful global solution that can handle huge amounts of data and scale effectively by engaging more computing resources and server space. It works great for big data analytics, long-term data storage and historical data analysis.

Using this technology, the data is instantly processed and transmitted to the device. The only catch here is that the edge nodes will transmit all types of data, even if it is of low or no significance. Compared to edge computing, the process power and storage capacity are even lesser than cloud computing for IoT devices and sensors. Cloud computing provides high level and very advanced processing technology capabilities.

Fog and edge computing can be useful for offline communication and micro-operations performed at the edge where this data is produced (sensor/actuator), reducing operating costs and increasing speed. In cloud computing, third-party servers are fully disconnected from local networks, leaving little to no control over data. In fog computing, users can manage a lot of information locally and rely on their security measures.

Cloud Computing

Many people use fog computing and edge computing interchangeably because both involve bringing intelligence and processing closer to where the data is created. Since cloud computing deals with resources in remote locations, the collection and processing of data experiences a time lag. This time lag, although negligible in most cases, becomes a serious issue with real-time projects or time-sensitive applications like online gaming, e-commerce sites, etc. Even knowing the difference between cloud, fog and edge computing, it can be challenging to figure out which approach to pick and how to extract real benefits from it. The technology landscape for IoT and big data has been changing rapidly in the last several years.

It is less expensive to operate with fog computing as data is hosted and analyzed on local devices rather than transferring it to any cloud device. The data is processed at the end of the nodes on the smart devices to segregate information from different sources at each user’s gateways or routers. It provides access to the entry point of the different service providers to compute, store, communicate, and process data over the networking area. The cloud is all powerful and scales, but the fog is its obedient and highly capable servant. Exactly how computing at the edge will finally be implemented will come out of a competition between various vendors, consortiums, and standards. The result will be a complex hybrid system that puts computing power and decision making at whatever location is optimal.

Cloud Tutorial

Fog computing cascades system failure by reducing latency in operation. It analyzes the data close to the device and helps in averting any disaster. Cloud has different parts such as frontend platform (e.g., mobile device), backend platform , cloud delivery, and network . Fog performs short-term edge analysis due to instant responsiveness, while the cloud aims for long-term deep analysis due to slower responsiveness. Unfortunately, there is nothing immaculate, and cloud technology has some downsides, especially for the Internet of Things services. PaaS — a development platform with tools and components for creating, testing and launching applications.

Flexibility In Network Bandwidth

Fog computing is useful when the Internet connection isn’t always stable. For instance, on connected trains, fog can pull up locally stored data in areas where the Internet connection can’t be maintained. It also allows implementing data processing at the local network closer to edge nodes, which is important for time-sensitive operations and real-time data analytics. This is what makes this approach more efficient and fast when comparing cloud vs fog computing.

Improved User Experience – Quick responses and no downtime make users satisfied. According to Statista, by 2020, there will be 30 billion IoT devices worldwide, and by 2025 this number will exceed 75 billion connected things. It increases cost savings as workloads can be transferred from one Cloud to another cloud platform. Cloud users can quickly increase their efficiency by accessing data from anywhere, as long as they have net connectivity. It works on a pay-per-use model, where users have to pay only for the services they are receiving for a specified period.
