What is Edge Computing & What are its Benefits?

Last updated on November 17th, 2022

People are now more likely to look into emerging possibilities that will, ideally, help them live better lives. The most recent technical developments have led to the development of new data processing techniques. Not only that but the data storage, processing, data analysis, and transportation of data are now transformed by edge computing. A great number of IoT and other devices are being adapted to this type of computing to deliver the best possible experience.

The goal of initial edge computing was mainly to minimize the amount of bandwidth needed to carry raw information from the point of origin. It could originate from a cloud or a commercial data center. Latest developments in real-world applications with minimal latency have helped to advance this approach. Examples include multi-camera video surveillance or automated driving.

On the other hand, due to 5G’s capability to speed up processing for such cutting-edge, low-latency use cases and applications, edge computing is closely associated with the current global undertaking of the 5G wireless benchmark.

Therefore in this article, we would go much deeper into the vital aspects of edge computing. A detailed view of its benefits and differences with cloud and fog computing will assist in getting a broader perspective.

What is Edge Computing? (Explained in Simple Terms)

Edge computing is a portion of a distributed computing method in which information processing gets placed near the edge location. To reduce latency levels, this is the place where objects and individuals generate or receive important data.

The underlying concept that edge computing is based on is that it lessens dependency on a central establishment that can be present thousands of miles away. It can bring processing and data storage nearer to the devices where information is being assembled. This is done to ensure that latency issues don’t affect an application’s ability to handle data, especially real-time data, without compromising its efficiency. Local processing makes it possible for companies to save money by lowering the amount of information that must be transferred to a centralized or cloud-based facility.

Take into account software that tracks manufacturing equipment on a company’s manufacturing plant or an internet webcam that transmits longer video from a distant workplace. Even when a piece of singular data-producing equipment could broadcast its information across a network with no difficulty, difficulties begin to arise as more devices begin to communicate information at the same time. Imagine, for instance, a large number of devices streaming live footage rather than a single camera. Due to major latency issues, the quality will eventually degrade, whereas bandwidth expenses can also soar without any warning signs.

You could give devices access to a nearby source of data processing and storage to solve this problem. By simply sending the significant information back to the cloud, an edge platform can quickly process information coming from an edge device. The capability to send information back to the edge device is accessible whenever a real-time application needs it.

How Does Edge Computing Work?

Although understanding the edge’s physical architecture can get somewhat complex, however, the essential concept is much simpler to grasp. Generally, client devices will get linked to neighboring edge modules for more rapid processing and more seamless movements. Now to recognize edge devices, think of various IoT sensors. It could be a worker’s computer or cellphone, surveillance cameras, or even microwaves that are also connected to the network.

A self-reliant roaming robot or a robot arm in an automotive plant is a model of edge devices in an industrial background. In the medical industry, it could allude to modern surgical equipment that allows doctors to operate remotely. An edge computing framework contains edge gateways as edge devices working to simplify the data processing method. Edge servers and edge gateways are buzzwords that may have come up in a discussion. However, even though the terminology differs, the basic concept of working remains the same.

What is the difference between Edge Computing, Cloud Computing, and Fog Computing?

Many distinguishing factors can separate each of these approaches from one another. The key differences, in particular, are the circumstances around where, when, and how endpoints equipment process and maintain data. However, to get a much-detailed look let us explore more:

Cloud computing 

When you compare it to any other type of storage, it is the one that gets located away from the endpoints. As the centralized storage gets located at a distance, it can be expensive yet effective. Not only that but there are the issues of larger latency, higher bandwidth expense, and network conditions, all of such can get lowered by this factor. The cloud functions as an effective, all-encompassing platform that can effectively scale to meet your specific requirements. It can handle huge volumes of information while utilizing more computational resources and server capacity. Additionally, this approach can be quite helpful for big data analytics, short or medium information processing, and archival data processing.

Fog computing

It functions as a transitional layer between the cloud and the edge while also offering the advantages of both. When distributing data that does not require quick processing, it can use the cloud as well as interact with it straight. Additionally, at the same time, fog is positioned closer to the edge. It employs local processing and storage resources as required for real-time analytics and quick reaction. It is a decentralized approach, suggesting it has numerous nodes, just as an edge. Fog, in comparison to the edge, includes network architecture. In order to allocate storage and computing resources more efficiently and to perform certain activities, the stations on Fog are often interlinked.

Edge computing

Due to its proximity to end equipment, it responds to data with the least latencies and within the quickest possible time. This method facilitates processing to get accomplished quickly. Additionally, some data is kept temporarily on computers, software programs, and edge portals. This kind of structure is commonly associated, with allowing edge nodes to manage data on their own. This factor alone sets edge fog apart from a network-based fog.

Edge Computing Technology Combined with IoT and 5G

Edge Computing Architecture

Edge integrates distributed and centralized structures quite effectively. To enable more new experiences, cloud and edge are now collaborating to deliver the best results. Within such a context, data will get created or gathered across several places and transported to the cloud. This is where computing will get consolidated and then processed at scale also at a lower expense. Edge computing handles sensitive data and reduces the expenditure of data transmission to the cloud while facilitating real-time responsiveness to create new experiences. By completing the work close to the source rather than sending it to a faraway cloud and then waiting for a response, Edge reduces latency. Therefore, developing technologies like 5G will push the edge to remain more productive, dependable, and manageable:

  • 5G will make edge implementations more seamless. It can guarantee the transfer of critical control messages that allow devices to make autonomous decisions. By connecting the edge to the internet backhaul, this technology makes sure that edge devices have the appropriate software-defined network configurations to carry out the necessary duties.
  • The IoT and linked devices are separate data sources that must get protected and recorded in the cloud. These data sources will be nearby or on Edge.

What are the Benefits of Edge Computing?

Businesses will be competent to reinvent experiences with the service of edge and cloud. Manufacturing and the Internet of Things are only a small portion of the possible uses for edge computing. Edge can get employed to facilitate quick decisions and enhance user experiences by boosting relevancy at every touchpoint. Nowadays, with the support of the more all-around cloud backbone, the edge is helping in the invention of new insights and experiences. Among some of the key advantages of edge computing are:

Rapid response

Transmission of data demands time. In other use scenarios, such as telesurgery or self-driving automobiles, there isn’t sufficient time to wait for data to journey back and forth from the cloud. In such circumstances, where real-time or highly immediate results are needed, Edge pushes the actions at a much faster speed.

The high volume of data

Although the cloud can accommodate tremendous amounts of data, there are some oversized transmission costs and physical restrictions on network capacity that need careful consideration. Processing the data at the edge is more beneficial in some circumstances because of the low expenses of handling a high quantity of data.

Easy remote utilization

Edge computing is valuable for someone who wants remote access to data processing. It can deliver faster responses and handle complicated data management efficiently.

Positive user experience

Edge makes vital data accessible to navigate future innovation and new business opportunities. This method of processing data is among the quickest, most dependable, and safest ones.
