"Edge computing" can sound like one of those technology buzzwords.
The basic idea is actually pretty simple.
Instead of sending everything to a remote cloud server, process some information closer to where it was generated.
Imagine a machine producing sensor data.
If something goes seriously wrong, you might not want to wait for the data to travel to a cloud server, get processed, and come back.
An edge device could make the first decision locally.
Something like:
Sensor
↓
Edge device
↓
Immediate decision
↓
Cloud
The cloud can still handle the heavy stuff:
Historical storage
Analytics
Model training
Reporting
So I don't really see edge and cloud as competing technologies.
They're often just different parts of the same system.
The interesting question is:
Which decisions need to happen locally, and which ones can wait?
