Google Cloud Professional Data Engineer Practice Exam 2025 – Complete Preparation

The primary function of Cloud SQL in Google Cloud is to manage and run relational databases. It is a fully-managed relational database service that supports popular database engines like MySQL and PostgreSQL. This service allows users to set up, maintain, manage, and administer relational databases in the cloud with minimal operational overhead.

Cloud SQL automates many of the routine tasks associated with database management, such as backups, patch management, and scaling, thus enabling developers and organizations to focus more on application development rather than on database maintenance. The service also provides high availability and strong security features, aligning with the needs of modern applications that require reliable and scalable database solutions.

Handling big data processing is more aligned with services like BigQuery or Dataflow, which are tailored for large-scale data analytics and transformation tasks. File storage services are generally managed by Google Cloud Storage, which is designed for object storage rather than relational data. Creating virtual machines is the function of Google Compute Engine, which focuses on infrastructure as a service; that is not the role of Cloud SQL, as it specifically addresses database needs.
