Just to be clear, this would be a managed service and you wouldn't need to create a droplet for your CloudSQL instance. It's a separate SQL package that is run externally to your droplets that you can access from your droplets, just like https://cloud.google.com/sql/docs/

Seems like a good idea, that would be very convenient for SQL based applications.

This is a big thing that’s holding me back from moving my entire infrastructure from GCP to DO. We had previous issues managing SQL on bare metal, and these managed solutions are super convenient.

Upvoting this, but I'm in need to a NoSQL service - hopefully building out the infrastructure for one would make the other easier anyway.
