Process Flow - Local processing vs cloud offloading
Data Generated by IoT Device
Local Processing Unit
Immediate Action/Output
Device Acts Fast
This flow shows how IoT data is either processed locally on the device or sent to the cloud for processing, depending on the decision point.
Execution Sample
IOT Protocols
data = sensor.read()
if data > threshold:
    device.process(data)
else:
    cloud.send(data)
This code reads sensor data and decides to process it locally if above a threshold, otherwise sends it to the cloud.

Key Moments - 2 Insights
Why does the device sometimes process data locally and other times send it to the cloud?
Because the condition 'data > threshold' decides the path. If true, local processing happens (see execution_table row 2), else data is sent to the cloud (row 6).
What happens after data is sent to the cloud?
The cloud receives the data for further analysis or storage, as shown in execution_table row 7, unlike immediate local action.
Visual Quiz - 3 Questions
Test your understanding
Look at the execution_table, what is the value of 'data' after Step 1?
A50
B75 or 30
Cundefined
DProcessed
💡 Hint
Check the 'Data Value' column in Step 1 of the execution_table.
At which step does the device decide to send data to the cloud?
AStep 2
BStep 3
CStep 6
DStep 7
💡 Hint
Look at the 'Branch Taken' column where the condition is false and cloud.send is called.
If the threshold changes to 80, what happens to data value 75 in Step 2?
ASent to cloud
BProcessed locally
CIgnored
DError
💡 Hint
Compare the condition 'data > threshold' with new threshold 80 for data 75 in execution_table.
Concept Snapshot
Local processing vs cloud offloading:
- IoT devices generate data.
- If data meets criteria (e.g., > threshold), process locally for fast response.
- Otherwise, send data to cloud for heavy analysis/storage.
- Local = quick, limited power; Cloud = powerful, latency involved.
- Decision depends on data and device capability.
Full Transcript
This visual execution shows how IoT devices decide between local processing and cloud offloading. The device reads sensor data, then checks if the data exceeds a threshold. If yes, it processes data locally for immediate action. If not, it sends data to the cloud for further analysis. Variables like 'data' change as sensor readings are taken and actions are decided. Key moments include understanding the decision point and what happens after sending data to the cloud. The quiz tests understanding of data values, decision steps, and effects of changing thresholds.
