What’s edge computing?
Edge computing moves data storage and computing closer to the devices that generate and consume it. Applications have traditionally sent sensor and smartphone data to a data center for processing.
Why Do Businesses Use Edge Computing?
Edge computing enables businesses to enhance remote device response times and gain faster, more valuable data insights. By removing network and datacenter bottlenecks, it supports real-time processing in remote locations. Without this technology, data from IoT devices can overwhelm company networks, causing slowdowns, rising IT costs, and poor system performance. This can lead to customer dissatisfaction and equipment failures. More importantly, companies relying on advanced sensors for worker safety could inadvertently compromise it without proper edge solutions in place.
How does edge computing work?
To allow real-time smart app and IoT sensor capabilities, edge computing tackles three interrelated issues:
- Connecting a device to a network from a remote location.
- Slow data processing due to network or computing limitations.
- Edge devices causing network bandwidth issues.
Why This Technology matter?
The benefits of edge computing include workplace safety, security, and efficiency.
1. Enhanced efficiency
Edge computing helps firms streamline daily operations by swiftly processing vast volumes of data near data gathering sites. This is more efficient than sending all data to a centralized cloud or core datacenter several time zones away, which would slow network performance.
2. Reduced IT costs
Edge computing reduces IT expenditures by processing data locally instead of in the cloud. This computing minimizes transmission, cloud processing, and storage costs by removing unnecessary data near collection.
3. Data sovereignty
While moving data to the cloud or a major datacenter across national borders may make data sovereignty compliance difficult, edge computing allows organizations to process and store data near its origin.
4. Enhanced employee productivity
Edge computing accelerates data delivery, boosting worker productivity. By enabling automation and predictive maintenance, it helps prevent equipment failures and minimizes disruptions in smart workplaces.
5. Improved workplace safety
Workers may avoid equipment failure and workplace changes with IoT sensors and edge computing. On offshore oil rigs, oil pipelines, and other remote industrial use cases, predictive maintenance and real-time data processing can improve worker safety and reduce environmental consequences.
6. Function remotely
Edge computing simplifies data utilization on remote locations with intermittent internet connectivity or poor network bandwidth, such as a Bering Sea fishing vessel or an Italian vineyard. Sensors continuously monitor and act on operational data like water or soil quality. A datacenter with internet access can process and analyze data.
7. Improved security
Adding thousands of internet-connected sensors and gadgets to a company network is risky. Edge computing lets businesses process and store data offline, lowering risk. This decreases network data and security risks.
8. Faster response times
Edge computing lets companies process data almost immediately without depending on cloud or datacenter infrastructure. Data from many sensors, cameras, and smart devices can be sent to a central location and cause latency, network congestion, and degraded data quality. Devices that process data at the edge of the network can instantly notify staff and equipment to mechanical problems, security concerns, or other important events, therefore guaranteeing prompt response.
Edge Computing Hardware and Networking
Edge devices include smart cameras, thermometers, robots, drones, vibration sensors, and other IoT devices. Although some devices have built-in compute, memory, and storage capabilities, not all do. Here are some components.
- Processors, including CPUs, GPUs, and their associated memory, drive IoT devices. The more powerful the CPU, the faster the system can handle tasks and support a higher volume of workloads.
- Clusters/servers are groups of servers that process data at an edge location, such as on a factory floor or at a commercial fishery. Enterprise apps, enterprise workloads, and an organization’s shared services often run on edge clusters/servers.
- Gateways are edge clusters/servers that perform essential network functions like enabling wireless connectivity, providing firewall protection, and processing and transmitting edge device data.
- Routers are edge devices that connect networks. For instance, an enterprise’s LANs can connect to a WAN or the internet through a router at the edge.
- Switches, also known as access nodes, link multiple devices to form a network.
- The term “nodes” encompasses the edge devices, servers, and gateways that facilitate IoT devices.
Edge computing characteristics
1. Fanless and ventless
Protecting edge hardware from dust, dirt, moisture, and other pollutants is crucial for maintaining reliability, particularly in industries where equipment failures can halt production and pose a risk to workers.
2. Temperature-resistant
We use outdoor edge hardware in cold, hot, and damp climates. It’s underwater sometimes. Many applications need sub-zero and near-boiling resistance.
3. Impervious to sudden movements
Hardware must tolerate environmental and mechanical disturbances. Building components without fans, cables, and other fragile interior parts is essential.
4. Small form factor
Compactness is crucial for edge computers. Must fit in narrow areas. Examples include smart shipping box thermometers, as well as wall, shelf, and ceiling cameras.
5. Equipped with ample storage
Edge computers that handle a large amount of data from edge devices may require a significant amount of storage capacity. They must instantly access and transfer enormous data sets.
6. Compatible with old and new gear
Production and factory edge computers have USB, COM, Ethernet, and general-purpose I/O. They can connect new and existing production equipment, machines, gadgets, sensors, and alarms.
7. Multiple connections
Edge computers are usually wired and wireless. The computer can communicate data even without wireless internet connectivity at a remote commercial site like a farm or ship at sea.
8. Several power inputs
Edge computers occasionally require multiple power inputs to provide remote power. Surge, overvoltage, and power protection are ways to avoid electrical damage.
9. Safe from cyberattacks
Attackers target edge devices, which network managers cannot control, as well as on-premises and cloud devices. Edge devices need firewalls and network-based IDSs to prevent malware and other intrusions.
10. Tamper resistant
Require protection from theft, damage, and unauthorized access due to their use in remote, unmonitored areas.
Edge computing uses and examples
IoT and edge computing are driving a transformation in global data management. Below are key use cases of this computing in the corporate world:
1. Branch office
Smart devices and sensors reduce secondary office resources. Security cameras, copier repair sensors, and HVAC controls are internet-connected. Edge computing sends only the most important device alarms to a company’s core datacenter, reducing server congestion and lag and speeding up facility issue response.
2. Manufacturing
Factory floor sensors can monitor equipment maintenance and worker safety. Smart factory and warehouse equipment improves efficiency, quality, and cost. Avoid costly and harmful delays by keeping data and analysis on the manufacturing floor.
3. Energy
Power and utility firms use IoT sensors and edge computing to automate the power grid, streamline maintenance, and solve remote connectivity issues. Built for tough locations like utility towers, wind farms, and oil rigs, these devices process data locally and only send pertinent data to datacenters. IoT sensors provide real-time insights to warn staff of equipment failures and safety threats.
4. Agricultural
Edge computing boosts agricultural efficiency. Farmers may employ weatherproof IoT sensors and drones to monitor equipment temperature and performance, soil, light, and other environmental data, optimize crop water and nutrient use, and time harvests. This technology lowers IoT costs in rural locations with inadequate networks.
