Overview
Cloud SQL for MySQL is a fully-managed database service that makes it easy to
set up, maintain, manage, and administer your MySQL relational databases on
Google Cloud. For information specific to MySQL, see theMySQL documentation.
Many configuration settings go into the creation of a Cloud SQL instance.
Your needs may vary from the defaults.
See theCreating instancesandInstance settingspages for
more information.
Connectivity
Cloud SQL offersconnectivitythroughpublicIP addresses,privateIP addresses, or both
public and private addresses.
Cloud SQL recommends usingSSL/TLS
certificateswhen connecting to a Cloud SQL instance.
Cloud SQL users
The first time you connect to a new Cloud SQL instance, use therootaccount.
Because it's a managed service, Cloud SQL doesn't allow MySQL users to haveSUPERprivileges.
Cascading read replicas
Database Migration Service lets you migrate data to a Cloud SQL destination instance,
and then set up cascading read replicas for that instance. For more information,
seeSet up cascading read replicas.
High availability
After youpromotea Cloud SQL replica to become a primary instance, you can configure it forhigh availability (HA). If your
HA-configured instance becomes unresponsive, then Cloud SQL automatically
switches to serving data from a standby instance.
