You have a MySQL schema with high read/write volume, need backups and capacity planning, and limited DBA time. How should you host the database?

Cloud SQL is the fully managed relational database service on Google Cloud, making it the ideal choice for a MySQL schema with high read/write volume when DBA time is limited. It handles backups, replication, patching, and capacity planning automatically, reducing operational overhead. Importing the existing MySQL schema directly into Cloud SQL is straightforward. Deploying MySQL from the Google Cloud Marketplace would require you to manage the underlying virtual machines, backups, and scaling yourself, which contradicts the goal of limited DBA time. Bigtable and Firestore are NoSQL databases and are not suitable for directly hosting a relational MySQL schema. Cloud Spanner is a globally distributed relational database, but it's typically used for applications requiring global consistency and massive scale beyond what a single-region MySQL instance can provide, and migrating a MySQL schema to Spanner would involve significant schema changes.
