For most organizations, the swift collection and analysis of data is crucial for streamlining operations, ensuring safety, and gaining timely IT and OT insights. Rapid computation and data management are also critically important for Industry 4.0, manufacturing automation, autonomous vehicles and other data-intensive applications. Edge computing solutions available today allow organizations to capitalize on the Internet of Things (IoT) by deploying smart devices at the network edge to reduce latency and bandwidth usage by managing data where it’s generated.
Qu'est-ce que l'informatique de périphérie ?
Edge computing is an architecture that uses a distributed computing model to eliminate data management inefficiencies and reduce latency. IoT and mobile devices within the distributed framework use IoT devices like embedded systems, cellular routers and serial servers to collect and process data at its source instead of transferring it to a central server, data center, or cloud solution for processing, as would be required with a traditional approach to cloud computing and IoT data management.
The edge computing model enables organizations to save bandwidth, time, and money. This model harnesses the power of smart edge devices, edge intelligence and cellular connectivity as a means of reducing cross-network traffic and enhancing efficiency. Artificial intelligence (AI) and machine learning (ML) can accelerate the processing speed of the IoT architecture by performing edge analytics, identifying patterns, taking actions and routing data.
IoT and Edge Computing
IoT refers to a variety of data collection devices, which may or may not process data at the edge. Some examples of IoT devices include:
- Manufacturing production monitors
- Health wearables
- Security motion sensors
- Smart lighting systems
- Self-driving vehicles
- Smart traffic light controls
- Environmental monitoring sensors
- Smart utility meters
- Fleet tracking devices
Edge computing in IoT allows devices to increase data usage efficiency and streamline operations. When coupled with edge computing technology, IoT devices can support real-time data processing to improve data routing speeds in critical applications, provide improved bandwidth management, and lower data costs.
How Does Edge Computing Work?
Edge computing solutions support a range of operational goals. The edge infrastructure can include cameras, sensors, and a range of IoT devices that perform processing immediately and locally, and route only specific data to centralized servers for further analysis, operational insights or storage. Intelligent edge devices can also take a number of actions, from performing analytics, to initiating reports or service tickets, to immediately causing machinery or operations to cease due to safety issues.
After initial processing, edge computing devices determine what data needs to transfer to other systems. As a result, the amount of data sent over the network is limited, ensuring only critical information is relayed to data centers or cloud solutions for business intelligence. A combination of purpose-built edge computing chips, device processing capabilities and remote monitoring and management tools are required to enable this sophisticated edge computing paradigm.
Edge Processing
Traditional approaches to data analysis typically rely on centralized processing solutions, such as data centers, cloud solutions, or servers. While those methods provide sufficient computing power, they require sending data from IoT devices or other collection points across the network for processing. Ultimately, that leads to latency and requires significant bandwidth, resulting in less efficiency.
With an edge deployment, mobile, IoT, and other edge computing devices have processing capabilities to analyze collected information and support automation, real-time decision-making or operational adjustments. This is accomplished using embedded edge chips and smart edge devices, allowing immediate edge processing where data is generated.
Edge computing benefits, compared with fog computing, are also considerable. With fog computing, there’s a processing layer between the edge layer and the central data center or cloud solution. While those servers assist with processing, they still require data transmission away from the collection point, and that can use substantial bandwidth and lead to latency. Distributed edge computing allows each edge device across the network to collect, store, and process data on its own. A consistent connection to the network is often not required, allowing operations to continue regardless of connection stability.
Edge Infrastructure
Edge infrastructure encompasses all network components, connected mobile devices and IoT access points within the broader system. The exact edge computing hardware and software solutions vary, and may include a range of edge computing nodes and devices:
There is also a software component to consider. For example, platforms like Digi Remote Manager® allow organizations to monitor and control hardware at the edge, making them a necessary part of the equation.
For example, Digi Remote Manager provides network-wide visibility, remote access, device configuration and security monitoring from a “single pane of glass.” Additionally, this solution provides instant alerts and notifications from the network edge, based on specified conditions, and enables out-of-band access to edge devices for remote management.
