Lesson notes
Key points
- Edge computing processes data on devices or local servers near where it is generated, instead of a distant data centre.
- The main gain is lower latency, meaning less delay, because data does not travel far before a decision is made.
- In a mine, a local gateway can detect dangerous gas readings and trigger alarms instantly, then send summaries to the cloud.
Definitions
- Edge computing
- Running computation close to the data source, on local devices or gateways, rather than only in remote cloud data centres.
Takeaway: Edge computing moves processing close to data for faster decisions.
