The Tiers resource represents a service configuration that can be used to define a Cloud SQL instance. Each tier has an associated RAM, maximum storage, and list of regions in which the tier can be used. Available tiers vary depending on whether you use Second Generation or First Generation instances. (Note that, for Cloud SQL Second Generation instances, machine types replace tiers.)
