Difference Between Cloud Computing And Fog Computing

Some edge computing applications do not process data right at the sensors and actuators that collect data. However, the computing is still located relatively close to the data source, such as IoT gateways or even rugged edge computers. Architecture, all the processing is happening at the edge and only delivers information to the cloud for further analytics and storage. Edge computing typically occurs directly on the sensors and devices deployed at the applications or a gateway close to the sensors.

In addition, the rich I/O features allow the AI computer to communicate with multiple IIoT devices and sensors. The edge computing model shifts computing resources from central data centers and clouds closer to devices. The goal is to support new applications with lower latency requirements while processing data more efficiently to save network cost.

What Is Fog Computing And Edge Computing?

Therefore, the benefits of fog computing and edge computing enable companies and organizations to pave the way for their digital transformation faster than ever. This blog will further explain fog computing vs edge computing and their differences. An excellent example of fog computing is an embedded application within a production line automation. Running automation within a production line will incorporate various IoT devices, sensors, and actuators. These embedded devices can include temperature sensors, humidity sensors, flow meters, water pumps, and more. Then, amid the production line, all of these edge devices and sensors are constantly measuring analog signals based on their specific function.

However, by implementing an additional layer between the cloud and the edge, fog computing is adding complexity to the IoT network architecture. Edge devices locally store and process data and work with edge data centers to overcome any intermittent connectivity issues. From a service Fog Computing provider’s perspective, as shown in the diagram, edge computing is a continuum from the enterprise edge through the service provider’s infrastructure to the public cloud. In business terms, edge computing is best located where the applications or services are optimized.

An example use case is Internet of Things , whereby billions of devices deployed each year can produce lots of data. When data is processed at the edge instead of the cloud, backhaul cost is reduced. Modeled after clouds, cloudlets are mobility enhanced small-scale data centers placed in close proximity to edge devices so they can offload processes onto the cloudlet. They are particularly designed to improve resource-intensive and interactive mobile apps through the extra availability of low-latency computing resources. However, with an additional fog layer at the edge, the fog server would reduce the traffic by processing and filtering the collected data with a specific parameter to determine if it will need to go to the cloud. Some of the information may not be sent to the cloud at all since the fog layer does have capabilities for processing at its source.

Location Of The Edge

Data is analyzed locally and protected by the security blanket of an on-premises network or the closed system of a service provider. Fog computing is a term created by Cisco in 2014 describing the decentralization of computing infrastructure, or bringing the cloud to the ground. Highly flexible micro data centers can be custom built and configured to suit the implementation requirements of unique situations. This flexibility allows data centers to be rapidly deployed to underserved areas or disaster centers, for example. It will continue to enable many new use cases and open up opportunities for telecom providers to develop new services that reach more people.

We can avoid the complexity of owning and maintaining infrastructure by using cloud computing services and pay for what we use. They provide the same components as traditional data centers but can be deployed locally near the data source. Fog computing refers to decentralizing a computing infrastructure by extending the cloud through the placement of nodes strategically between the cloud and edge devices. I would claim that cloud computing already has all the elements of fog computing and that this is mostly the creation of a new term for marketing purposes. Cisco products and solutions can help you get started with edge computing. This environment is characterized by ultra-low latency and high bandwidth as well as real-time access to radio network information that can be leveraged by applications.

These analog signals are then turned into digital signals by the IoT devices and sent to the cloud for additional processing. In a traditional cloud environment, constant data telemetry can take up bandwidth and experience more latency, a key disadvantage for constantly moving data to the cloud. Devices, sensors, and actuators are connected right on the running applications. These devices gather and compute data in the same hardware or IoT gateways that are installed at the endpoint. Edge computing can also send data immediately to the cloud for further processing and analysis.

In turn, cloud computing services providers can benefit from significant economies of scale by delivering the same services to a wide range of customers. Installing edge data centers and IoT devices can allow businesses to rapidly scale their operations. This diagram depicts where the edge is located from various vendors’ view. However, a clear distinction needs to be made between devices with computer power and edge computing serving many devices simultaneously. Fog provides unique advantages for services across several verticals such as IT, entertainment, advertising, personal computing etc.

Unlike traditional data centers, Fog devices are geographically distributed over heterogeneous platforms, spanning multiple management domains. Cisco is interested in innovative proposals that facilitate service mobility across platforms, and technologies that preserve end-user and content security and privacy across domains. Fogging enables repeatable structures in the edge computing concept so that enterprises can easily push compute power away from their centralized systems or clouds to improve scalability and performance. To be possible, specialized hardware is required for both the fog and edge to process, store, and connect critical data in real-time. Though fog and edge computing can be similar, there are some distinctions that set them apart.
