Fog Computing vs Cloud Computing: Understand the Difference?

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. Fog computing works as an intermediate layer between a traditional centralized data storage system and edge devices.

Cloud has different parts like front end platform (e.g. mobile device), back end platforms , cloud delivery, and network . The fog has some additional features other than the ones provided by the cloud’s components which enhance its storage and performance at the end gateways. Firstly the signal is transmitted from an IoT device, and then data is sent through a protocol gateway at each node. Intelligent data management concepts are opening new avenues for organizations to make better data-centric decisions and extract … Quantum computing has lots of potential for high compute applications.

Improved User Experience

For data processing and storage, it depends on remote servers. Fog computing is when all of the processing happens at the edge of the network, close to where the data originated. This means that all of the computation doesn’t need to be done in the cloud—it can happen right where the data lives. It helps reduce latency, which makes it ideal for IoT applications like autonomous vehicles or smart buildings.

  • But the present cloud model lags in dealing with the evolved IoT.
  • It is an architecture that extends services offered by the cloud to edge devices.
  • Now, all the prominent cloud service providers offer you a high level of security.
  • Fog computing extends from the cloud to the edge of the network.
  • Fog computing addresses this problem by inserting a processing layer between the edge and the cloud.

With the right technology, medical services can be moved to the home of the patient. It uses local game centers to ensure low latency and a better experience during multiplayer online gaming. The most prominent use of fog computing in IoT is video surveillance which is used in shopping malls, streets, and other large public areas. The nodes can instantly detect anomalies in the crowd and alert authorities automatically in case of any sign of violence. To use the facilities of cloud computing, businesses can choose pay-as-you-go pricing. It also functions as a mediator that decides which information to process locally and which should be sent to the cloud.


Cloud providers have stringent security protocols that collectively reduce cyberattack risks. It’s not always possible to apply similar measures to edge devices. Shortening the overall travel time with edge and fog computing makes IoT workload handling safer. However, as Arquilla discussed, edge and fog computing support data decentralization, keeping the information safer. Operation at the extreme edge allows mist computing to gather resources with cloud networks and communication facilities accessible on the sensor. A mist device is an enhanced edge computing & fog device with qualities like professional cloud servers.

The data can be stored locally or pulled up from local drives — such storage combines online and offline access. High Security – because the data is processed by multiple nodes in a complex distributed system. But still, there is a difference between cloud and fog computing on certain parameters.

Finally, if there is no internet connection, the cloud becomes inaccessible. Fog technologies apply dozens of protocols to avoid system failure, maximizing availability globally. You could say that it is a very good enhancement to cloud computing that generates a better user experience. Low latency – Fog tends to be closer to users and can provide a quicker response. 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.

Cloud computing in IoT environment

Fog computing mainly provides low latency in the network by providing instant response while working with the devices interconnected with each other. With fog computing, you see a decentralized approach that utilizes the edge of the network for data storage and processing. Arquilla continued, “The fog is a form of edge computing and consists of those structures between systems that produce data and the cloud.

The second benefit of cloud computing is that it makes it much easier to share data with others. Since there’s no need for everyone involved in a project or email chain to have a copy of all the data, only one person needs to be given exclusive permission. The other people just need read-only access to be able to view files as needed. This is especially useful when multiple people are working on a project together and need access to one another’s files without compromising security. Cloud computing and fog computing are two forms of distributed computing.

As the Cloud operates on the Internet, it is more likely to collapse in case of unknown network connections. Fog is a more secure system with different protocols and standards, which minimizes the chances of it collapsing during networking. No problems with bandwidth — pieces of information are aggregated at different points instead of sending them together to one center via one channel. Check out this quick guide to understand and implement the process in a simple way. Fog is a more secure system as it has various protocols and standards which reduces its chance of being collapsed while networking.

Fog Computing vs Cloud Computing: all you need to know in one place

This feature is highly beneficial for companies with a hybrid or remote team. With cloud computing, you can scale up and down the resource and infrastructure usage according to your requirements. Using fog computing means no complaints about the loss of connection. It uses multiple interconnected channels to ensure the best connectivity for any activity. Fog computing is a part of cloud computing, and hence, these are interconnected.

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. Edge computing processes data away from centralized storage, keeping information on the local parts of the network — edge devices and gateways.

Some companies are already using fog computing to more efficiently store data and provide services. The US Navy, for example, is using this concept to power its ships with more efficient storage without sacrificing any security or functionality. 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. However, concerns around the security of the data, once it is in motion between the endpoint and the data center, are not completely unwarranted.

fog computing vs cloud computing

We’ve already got used to the technical term cloud, which is a network of multiple devices, computers and servers connected to each other over the Internet. The main benefits that can be obtained are from Fog computing compared to cloud computing. Fog computing has low latency and provides a high response rate and has become most recommended compared to cloud computing. It supports the Internet of Things as well as compared to Cloud Computing.

The technology landscape for IoT and big data has been changing rapidly in the last several years. Adoption of cloud and other forms of computing for IoT requires skills and expertise. Cloud technology already brings multiple benefits to the Internet of Things, but progress doesn’t stop here. Right now, cloud, fog and edge technologies provide irreplaceable solutions to many Internet of Things challenges.

How Edge Computing vs. Fog Computing are Deployed

Cloud computing requires that all data is processed in the final server. It also helps with latency – the fog has a much lower latency than the cloud. Infrastructure as a Service or IaaSThis is when you rent all kinds of infrastructure, from servers to storage. Fog can also include cloudlets – small-scale and rather powerful data centers located at the network’s edge.

Flexibility in Network Bandwidth

Most edge and cloud computing architectures need components to make their data processes possible. Typically, cloud computing uses IoT gateways to organize and transport data through the network and route traffic while applying security protocols. Edge nodes create data from IoT devices with many different communication protocols usable by cloud computing. The problem is that gateways and edge nodes are no longer enough for IoT applications, such as a facial recognition system, that need real-time analysis at the edge.

#6. Power Distribution

For one, it makes it easier for data to be processed locally due to its proximity to the end-user. This allows the use of cheaper power sources and may lead to more efficient processing. This article will discuss Fog Computing Vs Cloud Computing, how this new concept in computing might be able to change the future of cloud computing. We’ll cover what fog computing is, why it’s important, and what it can do for cloud applications. Cloud computing is a model for providing scalable IT capabilities using off-site servers and other resources that are accessed through a web-based interface (e.g., via an API).

Enabling autonomous operations

While these two services can complement each other, none of it is replaceable by another one. Using fog and cloud computing, one can optimize the connected devices further in terms of data collection, storage, and processing. However, it takes substantial time and effort to design a serverless architecture that performs well and is easily maintained.

Here’s a cloud vs. fog vs. edge computing comparison chart that gives a quick overview of these and other differences between these approaches. If you want to start developing IoT software and make it accessible via fog computing, feel free to contact the Global Cloud Team at any time. Our specialists will assist with any question and provide valuable insights. We have previously mentioned that fog computing is an enhancement of the cloud version. High latency – More and more IoT apps require very low latency, but the Cloud cannot guarantee this due to the distance between client devices and data processing centers. We provide leading-edge IoT development services for companies looking to transform their business.

The back end is the system cloud section which is responsible for securing and storing data. Both these components are integrated to provide the user with a seamless networking platform and manage traffic on the ground. It provides access to the entry point of the different service providers to compute, store, communicate, and process data over the networking area. Most edge and fog computing use cases relate to the Internet of Things. That’s probably because most research on the matter has so far centered on IoT possibilities.

In comparison, Mist computing is the lightweight computing in the network web using simply micro-controllers and micro-chips. Fog computing relies upon many links to move data from the physical asset chain to the digital layer, which is a potential issue. Two such fog computing vs cloud computing cloud architecture is Fog Computing and Mist Computing architectures. Needs to review the security of your connection before proceeding. The information starts to finish encryption, so even specialist organizations have no admittance to the client’s substance.

When one talks about Cloud Computing vs. edge computing, the main difference worth looking at is how data processing occurs. Most of the data processing through the existing IoT systems is performed within the cloud, using a series of centralized servers. As a result of this, all the low-end devices and the gateway ones are used for aggregating data to perform low-level processing. Also require the processing of large volumes of real-time data to allow for efficient management. The sensors and other edge devices used in these applications are numerous and greatly dispersed.
