Google Cloud SQL provides a cloud-based MySQL database that is recommended for small- and medium-sized applications. It offers the same abilities and functions as MySQL along with some additional features. The RESTful Google Cloud SQL API provides methods for working with instances and retrieving information. The API can be used to create, delete, restart, and restore instances as well as import and export databases. Users can also get information on instances and backup runs along with lists of project instances and available tiers of service.
