Google Cloud SQL
What Google Cloud SQL is
Google Cloud SQL is a fully managed cloud relational database service for MySQL, PostgreSQL, and SQL Server. It supports automated backups, high availability, read replicas, scaling, and point-in-time restoration. Backup retention can extend up to 35 days, though plan details specify different recovery-log retention periods. Database Migration Service supports migrations from on-premises systems, Compute Engine, and other clouds; lift-and-shift migrations to Cloud SQL are available at no additional charge. Integrations include Compute Engine, Cloud Run, Google Kubernetes Engine, Cloud IAM, BigQuery, and Datastream, as well as Looker and Terraform. Cloud SQL encrypts data in transit on Google’s internal networks and at rest, and supports private VPC connectivity and network firewalls. The paid service is listed from $0.04, with no free plan and a free trial. The dedicated trial provides PostgreSQL and MySQL Enterprise Plus instances for 30 days without automatic charges, followed by a 90-day stopped state. MySQL supports only InnoDB.
