Pro Supports automatic encryption
Google Cloud SQL automatically encrypts all tables and temporary files.
Con AWFUL data integrity practice: Backup lifecycle is tied to instance lifecycle
If you are using Google CloudSQL, you are one command away from losing everything:
gcloud sql instances delete prod-instance-name
When you delete a CloudSQL instance, it also deletes the back-ups associated with that instance along with it. So if you accidentally delete your production database: Your backups? Poof. Gone.
It says this in the fine print of the on-demand backups documentation: https://cloud.google.com/sql/docs/mysql/backup-recovery/backups#about_on-dem
They persist until you delete them or until their instance is deleted.
There is also no way to mark a CloudSQL instance as "protected" so one bad CLI command can lose you your production database and all backups.
In order to get an actual backup workflow that will not affect production traffic, you must:
Don't fall for it. Protect your production data. Avoid busywork caused by poor product design. Avoid Google CloudSQL.
Con Performance limits
There are some performance limits when dealing with transactions for Google Cloud SQL.
