What Is Edge Computing? Everything You Need to Know

Edge computing provides solutions where traditional cloud infrastructure may fall short. A user’s physical proximity to a data center often has a direct impact on how quickly that user’s tools and apps can send and receive information, a factor known as latency. Streaming video services, for example, might experience latency delays of a few milliseconds, which aren’t likely to be perceptible to most users. 5G networks, which can clock in 10x faster than 4G ones, are built to allow each node to serve hundreds of edge devices, increasing the possibilities for AI-enabled services at edge locations.

NVIDIA also offers a host of other cloud-native technologies to help with edge developments. Often, edge computing is referred to as any computing outside of a cloud or traditional data center. Edge computing reduces data processing latency, increases response speed, and enables better network traffic management and compliance with jurisdictional requirements for security and privacy. One of the critical requirements for online as well as cloud gaming requires high-speed functioning. These often struggle with high lag and latency issues, causing major delays in gamers’ reactions. Edge computing can benefit gaming by creating edge servers closer to the gamers, thereby reducing latency and providing a rich and immersive gaming experience.

Edge computing definitions

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. But this virtual flood of data is also changing the way businesses handle computing. The traditional computing paradigm built on a centralized data center and everyday internet isn't well suited to moving endlessly growing rivers of real-world data. Bandwidth limitations, latency issues and unpredictable network disruptions can all conspire to impair such efforts.

This will allow organizations to take a view on their initiative of adopting edge computing technology. Increasing computing power at the edge is the foundation needed to establish autonomous systems, enabling companies to increase efficiency and productivity while enabling personnel to focus on higher value activities within the operation. Retailers can use edge nodes as an in-store clearinghouse for a host of different functionality, tying point-of-sale data together with targeted promotions, tracking foot traffic, and more for a unified store management application.

How does edge computing work?

That enormous data volume requires edge computing to apply automation and machine learning to access the data, ignore "normal" data and identify problem data so that clinicians can take immediate action to help patients avoid health incidents in real time. Edge computing puts storage and servers where the data is, often requiring little more than a partial rack of gear to operate on the remote LAN to collect and process the data locally. In many cases, the computing gear is deployed in shielded or hardened enclosures to protect the gear from extremes of temperature, moisture and other environmental conditions. Processing often involves normalizing and analyzing the data stream to look for business intelligence, and only the results of the analysis are sent back to the principal data center. In traditional enterprise computing, data is produced at a client endpoint, such as a user's computer.

Another great option is to invest in those technologies that can work from anywhere, be it on-premise, cloud, or at the edge. Containers and Kubernetes are examples of lightweight application technologies that promote application development from cloud to edge. Contrary to popular belief, edge and cloud are not fighting among themselves for the top spot.

The idea is that your toaster should be as difficult to hack, and as centrally updated and managed, as your Xbox. Voice assistants typically need to resolve your requests in the cloud, and the roundtrip time can be very noticeable. Then, in the Unix era, we learned how to connect to that computer using dumb terminals. Next we had personal computers, which was the first time regular people really owned the hardware that did the work. Stephanie Overby is an award-winning reporter and editor with more than twenty years of professional journalism experience. For the last decade, her work has focused on the intersection of business and technology.

  • The biggest problem of cloud computing is latency because of the distance between users and the data centers that host the cloud services.
  • Contrary to popular belief, edge and cloud are not fighting among themselves for the top spot.
  • These challenges can be addressed by working with knowledgeable system integrators and using the right edge technology.
  • Now more companies than ever before can harness comprehensive data analysis without the IT infrastructure needed in previous generations.
  • Sensitive information doesn’t need to pass through a network, and should a cyberattack to the cloud occur, the impact would likely be less dramatic than if the data was in flux.

On the factory floor, Internet of Things sensors generate a steady stream of data that can be used to prevent breakdowns and improve operations. By one estimate, a modern plant with 2,000 pieces of equipment can generate 2,200 terabytes of data a month. It’s faster—and less costly—to process that trove of data close to the equipment, rather than transmit it to a remote datacenter first. But it’s still desirable for the equipment to be linked through a centralized data platform.

Containers can be deployed on various hardware, regardless of device capabilities, settings and configurations. Management.The remote and often inhospitable locations of edge deployments make remote provisioning and management essential. IT managers must be able to see what's happening at the edge and be able to control the deployment when necessary.

Why Use Edge Computing?

Edge computing is a distributed IT architecture which moves computing resources from clouds and data centers as close as possible to the originating source. The main goal of edge computing is to reduce latency requirements while processing data and saving network costs. By the mid-2000s, large companies started renting computing and data storage resources to end users via public clouds. As cloud-based applications and businesses working from many locations grew in popularity, processing data as efficiently as possible became increasingly important.

Sensitive information doesn’t need to pass through a network, and should a cyberattack to the cloud occur, the impact would likely be less dramatic than if the data was in flux. Relying less on the cloud also means certain devices can operate reliably offline. This is especially useful in locations where internet connectivity is limited — whether in specific geographies with little access or remote, definition of edge computing often inaccessible sites like oil fields. Thus, it’s important to understand that while edge computing complements cloud computing and works very closely with fog computing, it is by no means here to replace either. Additionally, they came to realize that the infrastructure for transferring, storing and processing large volumes of data can be extremely expensive and difficult to manage.

This has led to the development of a new technology called edge computing moves computing closer to end users. Edge cloud computing augments cloud computing with edge computing for certain types of workloads. Compared to traditional forms of compute,edge computingoffers businesses and other organizations a faster, more efficient way to process data using enterprise-grade applications. In the past, edge points generated massive amounts of data that often went unused.

For example, a train may contain sensors that can immediately provide the status of its engine. In this scenario, sensor data does not need to travel to a data center, whether on the train or in the cloud, to see whether something is impacting operations or not. The evolution of AI, IoT and 5G will continue to catalyze the adoption of edge computing. The number of use cases and the types of workloads deployed at the edge will grow.

The main difference is that, with edge computing, you’re distributing software and code instead of static assets, as you would with a CDN. Alibaba Cloud IoT platform provides edge computing and other capacities to empower various IoT scenarios and industry developers. However, a clear distinction needs to be made between devices with computer power and edge computing serving many devices simultaneously. It will continue to enable many new use cases and open up opportunities for telecom providers to develop new services that reach more people. Immediate revenue models include any that benefit from greater data speed and computational power near the user. Edge computing can either use existing devices (routers, servers, gateways, switches,…), telecom base stations or dedicated physical components known as cloudlets (‘data centre in a box’) with the extensive use of virtualisation techniques.

Applications running close to the end user in a mobile network also reduce latency and allow providers to offer new services. Yet, with more end users demanding cloud-based applications and more businesses working from multiple locations, it became necessary to process more data outside of the data center right at the source and manage it from one central location. One definition of edge computing is the use of any type of computer program that delivers low latency nearer to the requests. In his definition, cloud computing operates on big data while edge computing operates on "instant data" that is real-time data generated by sensors or users.

What is edge computing

It's critical to design an edge deployment that accommodates poor or erratic connectivity and consider what happens at the edge when connectivity is lost. Autonomy, AI and graceful failure planning in the wake of connectivity problems are essential to successful edge computing. Compare edge cloud, cloud computing and edge computing to determine which model is best for you. Choosing which data to monitor and act on can be a difficult task for conventional system architectures. To keep up with the speed of business today, data must be processed and analyzed where it is most effective, on the edge.

The Cloud and the Edge

Retailers are also leveraging edge computing to make shopping a safer experience amid the Covid-19 pandemic. AT&T’s CTO of Network Services, Andre Fuetsch, said at the Wells Fargo 5G Forum in June 2020, these technologies could help retailers comply with social distancing regulations via real-time feedback using cameras with computer vision technology. Swans Trail Farm in Snohomish, WA, has embarked on a similar initiative to increase efficiency as part of the Food Resiliency Project spearheaded by the University of Oregon. Right now, smart farms wanting to improve connectivity are investing in expensive fiber, microwave connections, or having a full-time satellite; edge computing provides a suitable cost-effective alternative.

Since edge computing processes data locally — on the edge of the network, instead of in the cloud or a centralized data center — it minimizes latency and data transit costs, allowing for real-time feedback and decision-making. The origins of edge computing lie in content distributed networks that were created in the late 1990s to serve web and video content from edge servers that were deployed close to users. Banks may need edge to analyze ATM video feeds in real-time in order to increase consumer safety. Mining companies can use their data to optimize their operations, improve worker safety, reduce energy consumption and increase productivity. Retailers can personalize the shopping experiences for their customers and rapidly communicate specialized offers.

Why edge computing is the future of cloud

Data's journey across national and regional boundaries can pose additional problems for data security, privacy and other legal issues. Edge computing can be used to keep data close to its source and within the bounds of prevailing data sovereignty laws, such as the European Union's GDPR, which defines how data should be stored, processed and exposed. https://globalcloudteam.com/ This can allow raw data to be processed locally, obscuring or securing any sensitive data before sending anything to the cloud or primary data center, which can be in other jurisdictions. Improved healthcare.The healthcare industry has dramatically expanded the amount of patient data collected from devices, sensors and other medical equipment.

Considering that IoT and edge computing are still in their relative infancy, their maximum potential is far from full realization. At the same time, they are already accelerating digital transformation across many verticals, as well as changing day-to-day lives around the world. If a Computer A needs to ask Computer B, half a globe away, before it can do anything, the user of Computer A perceives this delay as latency. The brief moments after you click a link before your web browser starts to actually show anything is in large part due to the speed of light.

Location of the edge

Breaking down silos is crucial in this case, as one party cannot understand the requirements or perform the duties of the other. Edge computing is a frequent and popular means of enhancing networks to promote efficiency. Security optimization - the security risk footprint is reduced because less unencrypted data is sent over the network. Roadmap.sh Community created roadmaps, articles, resources and journeys for developers to help you choose your path and grow in your career. This approach has the advantage of being easy and relatively headache-free in terms of deployment, but heavily managed services like this might not be available for every use case.

But to truly capture the benefit of the massive amounts of data being collected, real-time analysis may be necessary — and while many wearable devices connect to the cloud directly, others can operate offline. But it’s not just autonomous vehicles that generate a significant amount of data and require real-time processing. It’s also planes, trains, and other forms of transportation — driverless or not. Despite significant advances in edge computing and other autonomous vehicle technologies, fully automated vehicles remain highly ambitious.

Intel® Edge Computing Technology and Solutions

Transportation.Autonomous vehicles require and produce anywhere from 5 TB to 20 TB per day, gathering information about location, speed, vehicle condition, road conditions, traffic conditions and other vehicles. And the data must be aggregated and analyzed in real time, while the vehicle is in motion. This requires significant onboard computing -- each autonomous vehicle becomes an "edge." In addition, the data can help authorities and businesses manage vehicle fleets based on actual conditions on the ground. In other cases, network outages can exacerbate congestion and even sever communication to some internet users entirely - making the internet of things useless during outages. Analysis occurs locally, on large sets of data without incurring the latency overhead that would be experienced if this analysis needed to be done in the cloud. Local connectivity also adds higher resiliency and ensures better responsiveness to critical situations, ensuring large volumes of data can be analyzed and scrubbed with only interesting data being sent to the cloud for additional analysis.
