An IT edge is where end devices connect to a network to deliver data and receive instructions from a central server, either a data center or the cloud. While this model worked in the past, modern devices generate so much data that companies require expensive equipment to maintain optimal performance. Companies, for example, can use a biometric security product with optical technologies to perform iris scans with edge devices instantly analyzing those images to confirm matches of workers with authorized access. Meanwhile, consumer security products, such as video doorbells and security cameras, likewise benefit from the real-time analysis that edge computing — often in the form of fog nodes deployed in the home network — delivers. While edge computing works very much like regular cloud computing for the end-user, edge devices share the computing task with servers. Furthermore, differing device requirements for processing power, electricity and network connectivity can have an impact on the reliability of an edge device.
Through their sensors, devices in the device layer collect and capture data used to help products achieve the purposes they are designed for. Equipment in a hospital collecting vital signs of patients and autonomous vehicles capturing data of other nearby vehicles are all such examples. For the longest time, centralized cloud computing has been a standard in the IT industry and continues to be the undisputed leader. A predecessor to edge, cloud computing is a huge tool for storing and processing computer resources in a central data center. On the other hand, edge computing is a distributed model that is most likely to be used by those applications and devices that require quick responses, real-time data processing, and key insights.
Enhanced customer services
In the mobile edge computing model, computing resources are deployed in service access point (SAP) locations or other locations in the core. Applications running on these edge computing servers can be accessed from mobile endpoints through 4G or 5G connections. Ranging from devices that are as small as our mobile phones or computers to ones that are as large as buses and factories, these devices are all examples of components in the device layer.
This process can cause between 10 to 65 milliseconds of latency depending on the quality of the infrastructure. In a setup with edge centers, the traffic is much lower than with a centralized system, so there are no bottleneck issues. Edge computing solves this problem by bringing processing closer to the device that generates data.
How Does Edge Computing Work
Traditional cloud setups are vulnerable to distributed denial of service (DDoS) attacks and power outages. As edge computing distributes processing and storage, systems are less prone to disruptions and downtime. Similar to the use of edge with augmented and virtual reality use cases, edge computing supports the low-latency requirements of video streaming and content delivery. Furthermore, it enables a good user experience for both existing and emerging features such as search functions, content suggestions, personalized experiences and interactive capabilities. Civic authorities are also using edge computing to create smart communities and run their roadways with capabilities such as intelligent traffic controls. For example, edge computing platforms deployed to process vehicle data can determine which areas are experiencing congestion and then reroute vehicles to lighten traffic.
An autonomous vehicle driving down the road needs to collect and process real-time data about traffic, pedestrians, street signs and stop lights, as well as monitor the vehicle’s systems. In terms of edge computing equipment, power consumption is an inevitable issue. That is, the more functions there are, the higher the power consumption will be. In terms of the wattage of power supply units (PSU), the equipment size and PSU size and wattage are proportional, i.e., the bigger the equipment is, the greater the wattage is required, and the larger the PSU size will be.
Edge Computing Examples Across Vertical Industries
By processing data locally, the amount of data to be sent can be vastly reduced, requiring far less bandwidth or connectivity time than might otherwise be necessary. Computing tasks demand suitable architectures, and the architecture that suits one type of computing task doesn’t necessarily fit all types of computing tasks. Edge computing has emerged as a viable and important architecture that supports distributed computing to deploy compute and storage resources closer to — ideally in the same physical location as — the data source.
This is especially true for facilities in remote or rugged units with low connectivity and poor infrastructure. When selecting a platform, it is necessary to target the ones with simplified security and lesser downtime. Companies can now harness the power of comprehensive data analysis by adopting a massively decentralized computer infrastructure in edge computing. The edge computing framework keeps data https://www.globalcloudteam.com/ close to the source, whereas 5G technology’s lightning-fast speed gets the data to its desired location as quickly as possible. Elements that change rapidly and require more processing power are processed on the cloud. Companies such as Nvidia continue to develop hardware that recognizes the need for more processing at the edge, which includes modules that include AI functionality built into them.

Learn about dedicated servers for gaming, servers that allow players to customize and control their gaming experience. Edge devices can serve as a point of entry for cyberattacks through which an attacker can inject malicious software and infect the network. This approach has the advantage of being easy and relatively headache-free in terms of deployment, but heavily managed services like this might not definition of edge computing be available for every use case. That’s a lot of work and would require a considerable amount of in-house expertise on the IT side, but it could still be an attractive option for a large organization that wants a fully customized edge deployment. Red Hat Enterprise Linux provides a large ecosystem of tools, applications, frameworks, and libraries for building and running applications and containers.
Benefits of Edge Computing
In simplest terms, edge computing moves some portion of storage and compute resources out of the central data center and closer to the source of the data itself. Only the result of that computing work at the edge, such as real-time business insights, equipment maintenance predictions or other actionable answers, is sent back to the main data center for review and other human interactions. It offers some unique advantages over traditional models, where computing power is centralized at an on-premise data center. Putting compute at the edge allows companies to improve how they manage and use physical assets and create new interactive, human experiences. Some examples of edge use cases include self-driving cars, autonomous robots, smart equipment data and automated retail. Sending large quantities of data from its origin to centralized data centers is expensive because it requires more bandwidth.
Today, less than 10 percent of enterprise-generated data is created and processed at the edge, according to Gartner; but by 2025, that will grow to 75 percent, Gartner predicts. In a traditional setting, data is produced on a user’s computer or any other client application. It is then moved to the server through channels like the internet, intranet, LAN, etc., where the data is stored and worked upon. Therefore, the machine operators must integrate any edge compute device right into the machine. That way they can leverage edge compute to pre-process and evaluate the data from all sensors directly on the machine.
Will Edge Computing Take Off?
From cable to streaming, the means of consuming content have rapidly changed over the years. While HD video streaming requires high bandwidth, consumers, on the other end, need a smooth streaming experience. Content delivery can be improved significantly by moving the load nearby and caching content on edge.
