Smart cities, Factory 4.0, autonomous cars… AI is not always enough to smoothly orchestrate numerous sensors that work differently with different linking technologies. For greater responsiveness, edge computing makes it possible to decentralize power and intelligence as close to the field as possible while ensuring network operations.
With the development of 5G, you’ll hear more and more about it, and yet, it’s not new:edgeedge Behind this mysterious expression computing lies a technology that moves part of the computing power as close to the field as possible. In this case sensorsensor In industry, for example, or smart cities, or more specifically for autonomous vehicles.
This process is also used in special cases, such as for environmental protection, such as equipment manufactured by Dell Technologies and IntelIntel : boarded tourist ships to restore photos of the Great Barrier Reef to help it BackupBackup. In this case, edge computing makes it possible to collect data autonomously and send it to the scientists’ servers as quickly as possible.
But, beyond sending raw data directly Information centerInformation center To process them, edge computing also makes it possible to analyze them directly. A practice that is intensifying with the generalization of usageArtificial intelligenceArtificial intelligence. Instead of simply monitoring and targeting conditions gathered from sensors, AI-enhanced edge computing now identifies risks of failure and predicts the future by issuing warnings before they occur too far from the data center.
Better yet, based on these predictions, the system can even automatically take corrective action if possible. To achieve this, one does not need the strike force of a data center whose connectivity is sometimes unreliable or slow due to distance. The main advantage of edge computing is to create several GatewayGateway Edge is staying close to their source. This makes it possible to pool their resources to benefit from sufficient computing power to use this AI.
In this video, Jean-Sébastien Volte, Product Manager Server France at Dell Technologies, paints a portrait of Edge Computing. For example, in Florida, Hard Rock Stadium generates 200 TB of data for each game.

Life is not just clouds
With such a mesh, we get a latency suitable for near real-time management, which is not the case when it is necessary to push data to the data center and receive instructions in response to its processing. Obviously, everything will depend on the type of data collected. Some do not require short response times. A strong data center link is essential for data collection to handle basic operations related to the system. But, when it comes to solving a concrete local situation, edge computing brings more fluidity.
Here’s the theory. In practice, setting up such a system would require a realistically small computer processing infrastructure to be deployed as close to the field as possible. It must be autonomous, robust and strong enough to withstand extreme temperatures, dust, humidity, shocks… In other words, it must work like proven military equipment.
Experts, such as Dell Technologies, determine the balance between robustness, processing power, storage density, economy constraints strengthstrength AndAutonomyAutonomy For edge units. And then, all these little worlds must sometimes be able to work together with different communication protocols, such as ADSL links, satellite, 4 or 5G, even links. RadioRadio Specific.
Under these conditions, SD-Wan is the ideal conductor for fast data routing. Finally, we must not forget that this is necessary due to the sometimes impossible location where these units are placed MaintenanceMaintenance Can be performed reliably without the need for direct intervention. And, in case of a major failure, the repair operation must be completed as soon as possible and on site. You get it: We’re not done hearing about the benefits of edge computing.
