In this 7 week project: First we’ll did HTTP. Then well did MQTT Arudion with sensors, hook to core IoT which is mqtt broker, then we have rules, to dynamoDB etc. Then we got into databases: Among others we went into Timeseries databases, but mainly SQL-LITE/Postgress-SQL doesn’t enforce a lot of rules, its easy. We used AWS to run some stuff. It’s a good thing to learn. If you want to use Microsoft Azure or Google Cloud, that's great.
