This video was BEYOND HELPFUL omg because I was lost in the mffff sauce !! That pyramid diagram really gave me a great visual to understand what was going on because just reading had me so confused ! Thank you so so much!
Great video !! .. but I have a question: imagine I have ESP32 connected to a temp sensor and I want to make analytics for the temp readings as in the example you've mentioned. I have the ESP32 as the edge computer, right ? and I have - for example - the Arduino IoT core as the cloud server that makes these analytics and graphs etc... what example of a Fog computer can be used in this case? Thanks
Thanks for the kind words and for the question! You can definitely look at the ESP32 as the edge computer in that scenario (it's doing the data collection right where the sensor is picking it up). In that instance, you could simply connect the ESP32 with the Arduino cloud without the need for a fog computer if you wanted, here's a tutorial for that with the caveat that we have not verified it: docs.arduino.cc/arduino-cloud/getting-started/esp-32-cloud. However, if you first wanted to batch your temperature information, do preliminary analysis on it, and then only send the relevant data you choose to the cloud for additional analytics and graph creation, you could insert a fog layer/device. For temperature measurement data a lower powered gateway would do the trick, but other factors like environment, space constraints, budget, and power draw play into the decision as well. If you used something like an IoT Gateway (www.onlogic.com/computers/iot-gateways/), you could probably use it for other tasks in addition to your fog-level computing.
