This page discusses the two levels of access control for Cloud SQL instances. You must configure both levels of access control before you can manage your instance.
Levels of access control
Configuring access control involves controlling who or what can access the instance. Access control occurs on two levels:
- Instance-level access
- Instance-level access authorizes access to your Cloud SQL instance from an application or client (running on an App Engine standard environment or externally) or from another Google Cloud service, such as Compute Engine.
- Database access
- Database access uses MySQL's access control system to allow MySQL users to have access to the data in your instance.
Instance-level accessConfiguring instance-level access depends on the connection source:
|Connection source||Configuration method||More information|
|App Engine standard environment||
|App Engine flexible environment||
|Google Kubernetes Engine||
After a user or application connects to a database instance, the user or application must log in with a user or service account. As part of creating a Cloud SQL instance, you set up the default user (root) account. You can also create more users to give you finer-grained control over access to your instance.
