Edge computing processes data closer to where it is created or used instead of sending every task to a distant data centre. The edge may be a sensor, gateway, local server or nearby network facility.
Edge vs cloud computing
Cloud computing provides scalable computing and storage in data centres. Edge computing moves selected processing closer to devices and users. The two approaches often work together: local systems handle time-sensitive tasks while the cloud supports storage and broader analysis.
Examples
- Factories detect equipment anomalies locally.
- Retail systems process selected inventory events in-store.
- Vehicles process sensor information onboard.
- Smart buildings respond to local sensors.
Benefits
Potential benefits include lower latency, reduced bandwidth use and resilience when connectivity is limited. These outcomes depend on the design.
Challenges
Distributed devices increase the systems that must be secured and maintained. Plan for device identity, encryption, patching, physical protection and data synchronisation.
FAQs
Is edge computing the same as IoT?
No. IoT describes connected devices; edge computing is one way to process their data.
Does it replace cloud services?
No, many deployments combine both.
