Data flows from IoT devices to the edge gateway, which processes and filters it before sending to the cloud.

Execution Sample

IOT Protocols

IoT Device -> Edge Gateway -> Process -> Filter -> Cloud

Shows the path data takes from devices through the edge gateway to the cloud.

Process Table

Step	Action	Data State	Result
1	IoT devices collect sensor data	Raw sensor data	Data ready to send
2	Send data to edge gateway	Raw sensor data	Data received by gateway
3	Edge gateway processes data	Raw sensor data	Data filtered and aggregated
4	Translate protocols if needed	Filtered and aggregated data	Data in cloud-compatible format
5	Store data locally if offline	Processed data	Data saved locally
6	Send processed data to cloud	Processed data	Data available in cloud
7	Cloud platform receives data	Processed data	Data ready for analysis
8	End	N/A	Data flow complete

💡 Data successfully processed and sent to cloud platform

Key Moments - 2 Insights

Why does the edge gateway process data before sending it to the cloud?

The edge gateway filters and aggregates data locally to reduce the amount sent to the cloud, saving bandwidth and improving response time, as shown in steps 3 and 6 of the execution table.

What happens if the cloud connection is lost?

The edge gateway stores processed data locally (step 5) until the connection is restored, ensuring no data loss.

Visual Quiz - 3 Questions

A Step 3

B Step 5

C Step 7

D Step 8

💡 Hint

Refer to the 'Action' column where local storage is mentioned.

Full Transcript

Edge gateway architecture involves IoT devices collecting data and sending it to an edge gateway. The gateway processes this data by filtering and aggregating it, then translates protocols if needed to make it compatible with the cloud platform. If the cloud connection is unavailable, the gateway stores data locally. Finally, the processed data is sent to the cloud for further analysis. This flow reduces bandwidth use and improves response times.
