EEPROM is not infinite.

Personally, I would output the data locally to an SD card using the SD library at the same time you upload it to the cloud. This means you will have your data and as sensor data, a large flash card will store huge amounts of data readings.

Your code could then send the file to a local machine at defined intervals for merging into a local DB, or simply merged to an Excel spreadsheet.
