Don't get too comfortable with Google or any big cloud provider (including Digital Ocean). They have their own reasons for doing what they do and those reasons are not at all aligned with you or any small/startup company.

I'll paraphrase a comment I saw on HN recently:

"The old advice 'save often in case of loss' has now become 'save often to prepare for when Google shuts you off'."

Use big cloud technology to learn and further your projects BUT DO NOT RELY ON IT (unless you like to gamble).
