Re: [google-cloud-sql-discuss] GCE connecting to MYSQL Cloud over internal address

For the Cloud SQL 1st generation instances the traffic to GCE VMs incurs no charges. The [1] says:

Network usage between Google App Engine applications, Google Compute Engine, or Google Cloud Storage and Cloud SQL are not charged.

The pricing for the network traffic for the Cloud SQL 2nd generation instances follows the GCE model [2].

The big downside is we have to pay Network traffic charges, right?  So if I read and write a lot of data to my Cloud SQL instance, I would have a bandwidth bill because I hit the public IP?  Or is Cloud SQL somehow excluded from the "public IP = bandwidth charge" rule?

FYI this is issue 113 on code.google.com. I don't know what the plan for this issue is, although we will update this issue when we have a solution. Perhaps someone from the Cloud SQL team can comment on the dev plans.

Until then we recommend using the external IP address of your Cloud SQL instance. You can achieve good access control by only authorizing the external IP addresses of your GCE instances. You can achieve encryption by using SSL. Additionally you should know that traffic between GCE instances and Cloud SQL instances does not exit Google's network at any time, even with external IP addresses.

I am trying to find information to see if Google is going to make this change. There is a message asking this question from 2013 and the google person was saying it was something they want to do. Is it still on the roadmap to be able to connect a GCE VM to the Google SQL Cloud over the Google private network. This would allow the data to be encrypted since it is on the private network and the Google SQL cloud would not even need an external IP address.
