A development team is building a new application that requires a relational database. The database will be deployed in a single region, needs to support up to 10 TB of data, and requires automated backups and high availability. Which GCP service should you recommend?

Cloud SQL is the ideal choice for regional relational database workloads up to 64 TB. It provides fully managed MySQL, PostgreSQL, and SQL Server with built-in high availability (regional failover) and automated backups. Cloud Spanner would be used if the requirement was for global horizontal scaling or > 64 TB.
