2.Filter non-actionable data.

3.Perform action on data.

4.Send critical data and action performed on data to cloud for storing.

B.

1. Acquire sensor data.

2.Send data to cloud for processing and to determine action.

3.Send required action back to edge for action completion.

4.Perform action on data.

C.

1. Acquire sensor data.

2.Filter non-actionable data.

3.Perform action on data.

D.

1. Acquire sensor data.

2.Perform action on data.
