Cloud SQL offers meaningful insights and manageability features, significantly reducing user toil.\n\nAs a Cloud SQL customer, you are responsible for configuring and operating Cloud SQL for your workload needs to get the most value from the service.\n\nGoogle's responsibilities\n-------------------------\n\n- Provision and maintain the underlying infrastructure, including hardware, firmware, kernel, OS, storage, network and more:\n - [Secure](/docs/security/infrastructure/design#secure_low_level_infrastructure) the low-level infrastructure, which includes the physical premises, the hardware in Google data centers, and the low-level software stack running on the machines.\n - Encrypt data in a Cloud SQL instance [at rest](/docs/security/encryption/default-encryption) by default and enable customer-managed encryption [in transit](/docs/security/encryption-in-transit).\n- Install and [maintain](/sql/docs/mysql/maintenance) the database software.\n - Provide configuration and tools to secure your Cloud SQL instance.\n - Provide limited access to database-specific functionality available to customers using flags, stored procedures, and plugins.\n - Increase instance storage capacity for instances configured to [enable automatic storage increase](/sql/docs/mysql/instance-settings#automatic-storage-increase-2ndgen).\n - Provide maintenance notifications, allow maintenance deferrals, and set maintenance denial periods.\n - Apply database vendor-provided fixes to instances as part of scheduled maintenance.\n - Make database vendor-provided fixes for known security vulnerabilities available for customers to apply proactively using self-service maintenance\n- Provide monitoring telemetry for various instance components including but not limited to:\n - CPU\n - Storage\n - Network\n - Memory\n - User connections\n- Provide [disaster recovery](/sql/docs/mysql/intro-to-cloud-sql-disaster-recovery) capabilities in case of region outages for instances configured with cross-region read replicas and instances configured with multi-region backups.\n- Provide high availability in case of zonal outages on instances configured for [high availability (HA)](/sql/docs/mysql/high-availability).\n- Provide actionable insights into instance sizing and idleness for cost optimization with the [Recommender service](/sql/docs/mysql/recommender-sql-idle).\n- Provide Google Cloud integrations for [Identity and Access Management (IAM)](/sql/docs/mysql/iam-overview), [tags](/sql/docs/mysql/tags), [Cloud Logging](/sql/docs/mysql/logging), [Cloud Key Management Service](/sql/docs/mysql/configure-cmek) and [Network Intelligence Center](/network-intelligence-center/docs).\n\nCustomer responsibilities\n-------------------------\n\n- [Create](/sql/docs/mysql/create-instance) instances with the appropriate version, location, size and [database flags](/sql/docs/mysql/flags).\n- Create and administer databases and any user-created code on the instance.\n- [Secure](/sql/docs/mysql/instance-access-control) access, authentication, and authorization using appropriate controls.\n- Configure and troubleshoot connectivity from client-side tooling to the Cloud SQL instance.\n- Configure the Cloud SQL instance for [high availability](/sql/docs/mysql/high-availability) and zonal/regional [disaster recovery](/sql/docs/mysql/intro-to-cloud-sql-disaster-recovery).\n- Use the [maintenance features](/sql/docs/mysql/maintenance) to control the business impact from maintenance events.\n- Manage, tune, and optimize the database performance based on the workload and instance configuration.\n- Configure [storage capacity](/sql/docs/mysql/instance-settings#storage-capacity-2ndgen) to accommodate future growth necessary for critical database maintenance events."]]
