    Also, if you want a nice way to encapsulate data, look at ArduinoJson (https://arduinojson.org/). All your information can be stored as easily identifiable strings in a JSON format. I use it all the time and it removes a lot of the mucking about with figuring out how to parse your data to/from file.

    I'd suggest sending data directly to AWS IoT Core (Free tier eligible) with the MQTT protocol. You can send data in JSON format. You could then use a serverless function to send that data to a DynamoDB (noSQL) database as the API is easy to use.

    I'm using arduino-json for my JSON serialization. I use SPIFFS.h as my SPIFFS foundation (I may move to FATFS in the future...). The JSON object stores the access point name, uid, password, etc. in text form. There are SPIFFS downloaders as well that integrate into PlatformIO and Arduino IDEs to preload the JSON file. Other JSON files on the device store application parameters and state information.
