After setup a 2nd generation mySQL failover instance in Cloud SQL, found that actually two IP addresses were provided, one for master, and another for failover instance.
From the picture above, how can we determine the "IP address X"? is it
- a separated load balancer IP?
- the IP of the master instance?
